Jazz Architecture

The Jazz architecture is optimized for rich media content delivered over broadband connections. The architecture is perfectly balanced between hardware and software with hardware acceleration of frequently-used low-level operations and software implementation of higher-level management tasks.

The Jazz architecture is composed of the following key components:

• Core Processor
  • Up to four instructions per cycle
  • Two hardware threads
  • Scalar Unit
    • 32-bit RISC architecture
  • Vector Unit
    • 256-bit register set
    • Integer and floating-point operations
    • Instruction set optimized for media
• Entropy Processor
  • Programmable multi-codec bit-stream processing
  • Supports MPEG-2, MPEG-4, AVS, VC-1 (WMV-9), H.264 (CABAC and CAVLC) entropy algorithms
• Motion Estimation Processor
  • Calculation of block motion vectors
  • MPEG-2, MPEG-4, VC-1 and H.264 search strategies

The default programming environment for the Jazz architecture is Linux. The hard real-time processing functions are embedded within a pluggable Media Framework to ensure maximum flexibility and robustness.
