Method to Design Low-Power Embedded Processor for Wireless Endoscope

This paper describes how to design a suitable micro processor for wireless endoscope. Before designer tune datapath for a specific application, the functions of processor should be analyzed first, and then ESL design tools should be used to make the exploration of design space easy. Additional to customizing processor´s architecture and instruction-set, several low-power technologies to improve the performance of such a processor have been introduction. At last, a few real results coming from Tensilica Xtensa and its toolkits show the advantages of ESL design tool for algorithm analysis and customization of processor´s architecture and instruction-set.
