CW5631 - Low Cost Comprehensive System-on-Chip Design

The ChipWrights CW5631 Visual Signal Processor (ViSP), is a System-on-Chip (SoC) designed for multi-purpose applications that require high-performance digital image processing, small size, and low power. The CW5631 SoC enables developers to design premium embedded multimedia designs for applications such as IPTVs, IP cameras, personal media players, digital video recorders, and digital signage applications at a very low cost.

Three Independent and Programmable Processing Cores:

• CWv16 SIMD DSP: Vector processor with sixteen 32-bit parallel datapaths controlled by a single instruction stream. Efficiently processes 2D data (still image and video processing), and array processing applications (audio encoding/decoding; encryption/ decryption). Typically, the CWv16 core runs audio and video codecs, image processing and image manipulation algorithms, and other computationally-intensive requirements of the system software.
  
  
• ARM926EJ-S RISC: Industry-standard ARM® 926EJ-S RISC core from ARM, Ltd. runs the operating and file systems, and most of the peripheral control software systems. With Memory Management hardware, it supports the true Linux operating system. It targets multi-tasking applications, providing complete memory management, high performance, small die size, and low power.
  
  
• Serial Application Processor: Propietary RISC processor core. Processes applications that are inherently serial and do not benefit from SIMD processing. Examples of these algorithms include all forms of Run Length Encoding from Huffman Encoding and Decoding, Context Adaptive Variable Length Coding (CAVLC), and Context Adaptive Binary Arithmetic Coding (CABAC) found in the Advanced Video Codec (AVC) standard.
