ADSP-21160M/ADSP-21160N is a high-performance 32-bit DSP chip from Analog Devices. It uses a Super Harvard architecture with 4 independent buses for dual data fetch, instruction fetch, and non-intrusive zero-overhead I/O. The chip is also backward compatible with ADSP-2106x DSP chips and has a single-instruction, multiple-data (SIMD) computational architecture, an integrated I/O processor, a 4M-bit on-chip dual-ported SRAM, glueless multiprocessing features, and ports (serial, link, external bus, and JTAG).
