ADSP-21160MKB-80

GENERAL DESCRIPTION

The ADSP-21160M SHARC DSP is the first processor in a new family featuring Analog Devices’ Super Harvard Architecture. Easing portability, the ADSP-21160M is application source code compatible with first generation ADSP-2106x SHARC DSPs in SISD (Single Instruction, Single Data) mode. To take advantage of the processor’s SIMD (Single Instruction, Multiple Data) capability, some code changes are needed. Like other SHARCs, the ADSP-21160M is a 32-bit processor that is optimized for high performance DSP applications. The ADSP-21160M includes an 80 MHz core, a dual-ported on-chip SRAM, an integrated I/O processor with multiprocessing support, and multiple internal buses to eliminate I/O bottlenecks.
