SUMMARY
DSP Microcomputer ADSP-21160
KEY FEATURES
High performance 32-bit DSP—applications in audio, medical, military, graphics, imaging, and communication Super Harvard Architecture—four independent buses for dual data fetch, instruction fetch, and nonintrusive, zero-overhead I/O Backwards compatible—assembly source level compatible with code for ADSP-2106x DSPs Single-Instruction-Multiple-Data (SIMD) computational architecture—two 32-bit IEEE floating-point computation units, each with a multiplier, ALU, shifter, and register file Integrated peripherals—integrated I/O processor, 4 Mbit on-chip dual-ported SRAM, glueless multiprocessing features, and ports (serial, link, external bus, & JTAG)
