Analog Devices Inc. ADSP-2157x Digital Signal Processors
Analog Devices ADSP-2157x Digital Signal Processors are members of the single-instruction, multiple data (SIMD) family of digital signal processors that feature Analog Devices Super Harvard Architecture (SHARC®). Analog Devices 32-bit/40-bit/64-bit floating-point processors are optimized for high-performance audio/floating-point applications with a large on-chip static random-access memory (SRAM), multiple internal buses that eliminate input/output (I/O) bottlenecks, and digital audio interfaces (DAI). These additions to the SHARC+® core include cache enhancements and branch prediction while maintaining instruction set compatibility to previous SHARC products.
