1. A Survey of Recent Media Processors
A ECE734 course project
Min Xu

2. Motivation Media processors is the most flexible DSP technology
Wide applications
Rapid development
Big market
High performance
Low power

3. Traditional Architecture
VLIW based
Wide issue width
Variable instruction length
SIMD data parallel
Subword operations
Saturation arithmetic
Multiple special processing units
AV codec, network, cryptography

4. Unique Architecture NUON SHARP DDMP Open standard for DVD and DTV
VM lab’s Aries 3 implementation
Operating system support
SHARP DDMP
Async pipeline, self timing
Low power

5. System Architecture SONY PlayStation 2 Implications
Extremely wide datapath
Big I$, small D$
High data bandwidth
Implications
Data parallelism VS. instruction level parallelism
High data throughput, low data locality
