1. Requirements Determine processor core Determine the number of hardware profiles and the benefits of each profile Determine functionality of each profile Help in the creation of an instruction set architecture for each profile Determine sequence of profiles

2. Requirements cont. Help to create and test decoder Help to resolve performance issues and to create reservation tables And most important…. Help any group that needs help understanding architecture of the hardware profiles or the DLX processor

5. Profiles Inverse Discrete Cosine Transform Inverse Quantisation Variable Length Decoder and Run Length Decoder

6. Benefits of profiles Inverse DCT - the algorithm lends itself to quick implementation in hardware - a hardware solution will reduce cycle time Inverse Quantisation - Needs tables in order to complete. By making it a separate profile the tables will only be loaded into memory when they are needed thereby freeing up resources.

7. Benefits of Profiles cont. Decoders -The variable length decoder profile also frees memory space by only loading the tables for this algorithm when they are necessary -We’re not certain if the Run Length Decoder will benefit by being in a separate profile yet. We’re including it in this profile for now because it makes some logical sense to keep both decoders together.
