A 4GOPS 3 way-VLIW image recognition processor for an automobile system has been developed. The processor is based on a configurable and extensible media processor enabling optimization for a specific application by means of design-time configuration. Using VLIW coprocessor extension, the processor can satisfy the performance requirements of the system. Overhead by VLIW-mode instructions is only 7%. The VLIW co-processor occupies only 12% of the die area. Thus, good cost-performance for media processing in each embedded system can be achieved by this configurable media processor.
