+provide legal services or legal advice. Distribution of Creative Commons public 
+licenses does not create a lawyer-client or other relationship. Creative Commons 
+makes its licenses and related information available on an “as-is” basis.

+
+### Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and conditions 
+that creators and other rights holders may use to share original works of 
+authorship and other material subject to copyright and certain other rights 
+specified in the public license below. The following considerations are for 
+informational purposes only, are not exhaustive, and do not form part of our 
+licenses.
+
+* __Considerations for licensors:__ Our public licenses are intended for use by 
+those authorized to give the public permission to use material in ways otherwise
+restricted by copyright and certain other rights. Our licenses are irrevocable. 
+Licensors should read and understand the terms and conditions of the license 
+they choose before applying it. Licensors should also secure all rights 
+necessary before applying our licenses so that the public can reuse the material
+as expected. Licensors should clearly mark any material not subject to the license. 
+This includes other CC-licensed material, or material used under an exception or
+limitation to copyright. 
+[More considerations for licensors](http://wiki.creativecommons.org/Considerations_for_licensors_and_licensees#Considerations_for_licensors).
+
+* __Considerations for the public:__ By using one of our public licenses, a 
+licensor grants the public permission to use the licensed material under 
+specified terms and conditions. If the licensor’s permission is not necessary 
+for any reason–for example, because of any applicable exception or limitation 
+to copyright–then that use is not regulated by the license. Our licenses grant 
+only permissions under copyright and certain other rights that a licensor has 
+authority to grant. Use of the licensed material may still be restricted for 
+other reasons, including because others have copyright or other rights in the 
+material. A licensor may make special requests, such as asking that all changes
+be marked or described. Although not required by our licenses, you are 
+encouraged to respect those requests where reasonable. 
+[More considerations for the public](http://wiki.creativecommons.org/Considerations_for_licensors_and_licensees#Considerations_for_licensees).
+
+## Creative Commons Attribution 4.0 International Public License
+
+By exercising the Licensed Rights (defined below), You accept and agree to be 
+bound by the terms and conditions of this Creative Commons Attribution 4.0 
+International Public License ("Public License"). To the extent this Public 
+License may be interpreted as a contract, You are granted the Licensed Rights in
+consideration of Your acceptance of these terms and conditions, and the Licensor
+grants You such rights in consideration of benefits the Licensor receives from
+making the Licensed Material available under these terms and conditions.
+
+### Section 1 – Definitions.
+
+a. __Adapted Material__ means material subject to Copyright and Similar Rights 
+that is derived from or based upon the Licensed Material and in which the 
+Licensed Material is translated, altered, arranged, transformed, or otherwise 
+modified in a manner requiring permission under the Copyright and Similar Rights
+held by the Licensor. For purposes of this Public License, where the Licensed
+Material is a musical work, performance, or sound recording, Adapted Material is
+always produced where the Licensed Material is synched in timed relation with a
+moving image.
+
+b. __Adapter's License__ means the license You apply to Your Copyright and 
+Similar Rights in Your contributions to Adapted Material in accordance with the
+terms and conditions of this Public License.
+
+c. __Copyright and Similar Rights__ means copyright and/or similar rights 
+closely related to copyright including, without limitation, performance, 
+broadcast, sound recording, and Sui Generis Database Rights, without regard to 
+how the rights are labeled or categorized. For purposes of this Public License,
+the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar 
+Rights.
+
+d. __Effective Technological Measures__ means those measures that, in the 
+absence of proper authority, may not be circumvented under laws fulfilling 
+obligations under Article 11 of the WIPO Copyright Treaty adopted on December 
+20, 1996, and/or similar international agreements.
+
+e. __Exceptions and Limitations__ means fair use, fair dealing, and/or any other
+exception or limitation to Copyright and Similar Rights that applies to Your 
+use of the Licensed Material.
+
+f. __Licensed Material__ means the artistic or literary work, database, or other
+material to which the Licensor applied this Public License.
+
+g. __Licensed Rights__ means the rights granted to You subject to the terms and
+conditions of this Public License, which are limited to all Copyright and 
+Similar Rights that apply to Your use of the Licensed Material and that the 
+Licensor has authority to license.
+
+h. __Licensor__ means the individual(s) or entity(ies) granting rights under 
+this Public License.
+
+i. __Share__ means to provide material to the public by any means or process 
+that requires permission under the Licensed Rights, such as reproduction, 
+public display, public performance, distribution, dissemination, communication,
+or importation, and to make material available to the public including in ways
+that members of the public may access the material from a place and at a time 
+individually chosen by them.
+
+j. __Sui Generis Database Rights__ means rights other than copyright resulting 
+from Directive 96/9/EC of the European Parliament and of the Council of 11 March 
+1996 on the legal protection of databases, as amended and/or succeeded, as well 
+as other essentially equivalent rights anywhere in the world.
+
+k. __You__ means the individual or entity exercising the Licensed Rights under 
+this Public License. Your has a corresponding meaning.
+
+### Section 2 – Scope.
+
+a. ___License grant.___
+
+   1. Subject to the terms and conditions of this Public License, the Licensor 
+   hereby grants You a worldwide, royalty-free, non-sublicensable, 
+   non-exclusive, irrevocable license to exercise the Licensed Rights in the 
+   Licensed Material to:
+
+       A. reproduce and Share the Licensed Material, in whole or in part; and
+
+       B. produce, reproduce, and Share Adapted Material.
+
+   2. __Exceptions and Limitations.__ For the avoidance of doubt, where 
+   Exceptions and Limitations apply to Your use, this Public License does not 
+   apply, and You do not need to comply with its terms and conditions.
+
+   3. __Term.__ The term of this Public License is specified in Section 6(a).
+
+   4. __Media and formats; technical modifications allowed.__ The Licensor 
+   authorizes You to exercise the Licensed Rights in all media and formats 
+   whether now known or hereafter created, and to make technical modifications 
+   necessary to do so. The Licensor waives and/or agrees not to assert any right
+   or authority to forbid You from making technical modifications necessary to
+   exercise the Licensed Rights, including technical modifications necessary to
+   circumvent Effective Technological Measures. For purposes of this Public 
+   License, simply making modifications authorized by this Section 2(a)(4) 
+   never produces Adapted Material.
+
+   5. __Downstream recipients.__
+
+       A. __Offer from the Licensor – Licensed Material.__ Every recipient of 
+       the Licensed Material automatically receives an offer from the Licensor 
+       to exercise the Licensed Rights under the terms and conditions of this 
+       Public License.
+
+       B. __No downstream restrictions.__ You may not offer or impose any 
+       additional or different terms or conditions on, or apply any Effective 
+       Technological Measures to, the Licensed Material if doing so restricts 
+       exercise of the Licensed Rights by any recipient of the Licensed 
+       Material.
+
+   6. __No endorsement.__ Nothing in this Public License constitutes or may be 
+   construed as permission to assert or imply that You are, or that Your use of 
+   the Licensed Material is, connected with, or sponsored, endorsed, or granted 
+   official status by, the Licensor or others designated to receive attribution 
+   as provided in Section 3(a)(1)(A)(i).
+
+b. ___Other rights.___
+
+   1. Moral rights, such as the right of integrity, are not licensed under this 
+   Public License, nor are publicity, privacy, and/or other similar personality 
+   rights; however, to the extent possible, the Licensor waives and/or agrees 
+   not to assert any such rights held by the Licensor to the limited extent 
+   necessary to allow You to exercise the Licensed Rights, but not otherwise.
+
+   2. Patent and trademark rights are not licensed under this Public License.
+
+   3. To the extent possible, the Licensor waives any right to collect royalties 
+   from You for the exercise of the Licensed Rights, whether directly or through
+   a collecting society under any voluntary or waivable statutory or compulsory 
+   licensing scheme. In all other cases the Licensor expressly reserves any 
+   right to collect such royalties.
+
+### Section 3 – License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the following
+conditions.
+
+a. ___Attribution.___
+
+   1. If You Share the Licensed Material (including in modified form), You must:
+
+       A. retain the following if it is supplied by the Licensor with the 
+       Licensed Material:
+
+         i. identification of the creator(s) of the Licensed Material and any 
+	 others designated to receive attribution, in any reasonable manner 
+	 requested by the Licensor (including by pseudonym if designated);
+
+         ii. a copyright notice;
+
+         iii. a notice that refers to this Public License;
+
+         iv. a notice that refers to the disclaimer of warranties;
+
+         v. a URI or hyperlink to the Licensed Material to the extent reasonably
+	 practicable;
+
+       B. indicate if You modified the Licensed Material and retain an 
+       indication of any previous modifications; and
+
+       C. indicate the Licensed Material is licensed under this Public License,
+       and include the text of, or the URI or hyperlink to, this Public License.
+
+   2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner
+   based on the medium, means, and context in which You Share the Licensed
+   Material. For example, it may be reasonable to satisfy the conditions by 
+   providing a URI or hyperlink to a resource that includes the required 
+   information.
+
+   3. If requested by the Licensor, You must remove any of the information 
+   required by Section 3(a)(1)(A) to the extent reasonably practicable.
+
+   4. If You Share Adapted Material You produce, the Adapter's License You apply
+   must not prevent recipients of the Adapted Material from complying with this
+   Public License.
+
+### Section 4 – Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that apply to Your
+use of the Licensed Material:
+
+a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract,
+reuse, reproduce, and Share all or a substantial portion of the contents of the
+database;
+
+b. if You include all or a substantial portion of the database contents in a 
+database in which You have Sui Generis Database Rights, then the database in 
+which You have Sui Generis Database Rights (but not its individual contents) is
+Adapted Material; and
+
+c. You must comply with the conditions in Section 3(a) if You Share all or a 
+substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not replace 
+Your obligations under this Public License where the Licensed Rights include 
+other Copyright and Similar Rights.
+
+### Section 5 – Disclaimer of Warranties and Limitation of Liability.
+
+a. __Unless otherwise separately undertaken by the Licensor, to the extent 
+possible, the Licensor offers the Licensed Material as-is and as-available, and
+makes no representations or warranties of any kind concerning the Licensed 
+Material, whether express, implied, statutory, or other. This includes, without
+limitation, warranties of title, merchantability, fitness for a particular 
+purpose, non-infringement, absence of latent or other defects, accuracy, or the 
+presence or absence of errors, whether or not known or discoverable. Where 
+disclaimers of warranties are not allowed in full or in part, this disclaimer 
+may not apply to You.__
+
+b. __To the extent possible, in no event will the Licensor be liable to You on 
+any legal theory (including, without limitation, negligence) or otherwise for 
+any direct, special, indirect, incidental, consequential, punitive, exemplary, 
+or other losses, costs, expenses, or damages arising out of this Public License 
+or use of the Licensed Material, even if the Licensor has been advised of the 
+possibility of such losses, costs, expenses, or damages. Where a limitation of 
+liability is not allowed in full or in part, this limitation may not apply to 
+You.__
+
+c. The disclaimer of warranties and limitation of liability provided above shall 
+be interpreted in a manner that, to the extent possible, most closely 
+approximates an absolute disclaimer and waiver of all liability.
+
+### Section 6 – Term and Termination.
+
+a. This Public License applies for the term of the Copyright and Similar Rights 
+licensed here. However, if You fail to comply with this Public License, then 
+Your rights under this Public License terminate automatically.
+
+b. Where Your right to use the Licensed Material has terminated under Section 
+6(a), it reinstates:
+
+   1. automatically as of the date the violation is cured, provided it is cured
+   within 30 days of Your discovery of the violation; or
+
+   2. upon express reinstatement by the Licensor.
+
+   For the avoidance of doubt, this Section 6(b) does not affect any right the 
+   Licensor may have to seek remedies for Your violations of this Public 
+   License.
+
+c. For the avoidance of doubt, the Licensor may also offer the Licensed Material
+under separate terms or conditions or stop distributing the Licensed Material
+at any time; however, doing so will not terminate this Public License.
+
+d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
+
+### Section 7 – Other Terms and Conditions.
+
+a. The Licensor shall not be bound by any additional or different terms or 
+conditions communicated by You unless expressly agreed.
+
+b. Any arrangements, understandings, or agreements regarding the Licensed 
+Material not stated herein are separate from and independent of the terms and 
+conditions of this Public License.
+
+### Section 8 – Interpretation.
+
+a. For the avoidance of doubt, this Public License does not, and shall not be 
+interpreted to, reduce, limit, restrict, or impose conditions on any use of the
+Licensed Material that could lawfully be made without permission under this 
+Public License.
+
+b. To the extent possible, if any provision of this Public License is deemed 
+unenforceable, it shall be automatically reformed to the minimum extent 
+necessary to make it enforceable. If the provision cannot be reformed, it shall 
+be severed from this Public License without affecting the enforceability of the
+remaining terms and conditions.
+
+c. No term or condition of this Public License will be waived and no failure to
+comply consented to unless expressly agreed to by the Licensor.
+
+d. Nothing in this Public License constitutes or may be interpreted as a 
+limitation upon, or waiver of, any privileges and immunities that apply to the 
+Licensor or You, including from the legal processes of any jurisdiction or 
+authority.
+
+> Creative Commons is not a party to its public licenses. Notwithstanding, 
+Creative Commons may elect to apply one of its public licenses to material it 
+publishes and in those instances will be considered the “Licensor.” Except for 
+the limited purpose of indicating that material is shared under a Creative 
+Commons public license or as otherwise permitted by the Creative Commons 
+policies published at

+avoidance of doubt, this paragraph does not form part of the public licenses.

+\subsubsection{Aufgabenstellung}
+
+Zur Klärung immerwiederkehrender Fragen im Umfeld des Vereins IT-Syndikat in
+Innsbruck sollen Beispiele und Dokumentation der Funktion moderner
+Prozessorperipherie und der Kommunikation selbiger mit dem Prozessorkern als
+MMIO
+\footnote{\href{https://en.wikipedia.org/wiki/Memory-mapped_I/O}{MMIO}... 
+Memory Mapped I/O} Angefertigt werden. Diese Dokumentation soll möglichst für alle
+Prozessorarchitekturen gültig und daher Architekturunabhängig sein. Die
+Dokumentation soll für Personen mit tieferem Verständniss von Hardware, sowie
+für Anfänger hilfreiche Aussagen über die Funktionswiese der Hardware liefern,
+welche sich aus einer seriellen Schnittstelle mit TIA-/EIA-232 Pegeln, einem
+Framebuffer\footnote{\href{https://en.wikipedia.org/wiki/Framebuffer}
+{Framebuffer}...Ein Speicherbereich in welchen
+ein Bild geladen werden kann, welches dann ausgegeben werden} und einem
+Soundbuffer\footnote{Ähnlich einem Framebuffer nur dass PCM-Audio anstatt 
+Bildern ausgegeben wird}.
+
+\subsubsection{Umsetungsbeschreibung}
+
+Zu aller erst müssen, um die ziele Verstehen zu können, die benötigten
+Unterlagen beschaffen werden. Diese können in Papierform oder Digital vorhanden
+sein. Letztere dürften leichter in diesem Industriezweig aufzutreiben sein,
+jedoch muss mehr Acht gegeben werden auf die Korrektheit der Dokumente.
+Nach der Beschaffung der Dokumente sollen Beispielschaltungen entwickelt werden,
+damit die Funktionsweise auch tatsächlich verstanden werden kann.
+Dokumentationen ohne sinnvollen Praktischen Hintergrund sind meist recht
+unanschaulich. Nach Entwicklung der Schaltungen sollen diese sinnvoll
+begründet werden und dann Dokumentiert werden. Die Dokumentation soll mindestens
+aus Schaltungsbeschreibung, einer generellen Bauteilbeschreibung und den
+Ideen hinter der aktuellen Umsetzung bestehen.
