GENERAL DESCRIPTION
The ADSP-21469 SHARC® processor is a member of the SIMD SHARC family of DSPs that feature Analog Devices’ Super Harvard Architecture. The processor is 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 (single-instruction, single-data) mode. The processor is a 32-bit/40-bit floating point processor optimized for high performance audio applications with its large on-chip SRAM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital applications interface (DAI).
