What are SHARC Processors? enables the SHARC user to leverage legacy code and design experience, while transitioning to higher-performance, more highly-integrated SHARC products. By integrating on-chip, single-instruction, multiple-data (SIMD) process- ing elements, SDRAM, and I/O peripherals, SHARC processors deliver breakthrough signal processing performance. SHARC Applications The combination of a high performance core surrounded by appropriate peripherals, a large software library, and a
