ADSP-21467 数据手册 ( 数据表 ) - Analog Devices

GENERAL DESCRIPTION
The ADSP-21467/ADSP-21469 SHARC® processors are members of the SIMD SHARC family of DSPs that feature Analog Devices’ Super Harvard Architecture. The processors are source code compatible with the ADSP-2126x, ADSP-2136x, ADSP-2137x, and ADSP-2116x DSPs, as well as with first generation ADSP-2106x SHARC processors in SISD (singleinstruction, single-data) mode. These 32-bit/40-bit floatingpoint processors are optimized for high performance audio applications with their large on-chip SRAM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital applications/peripheral interfaces (DAI/DPI).
