Analog Devices Inc. ADSP-21591/ADSP-21593 SHARC+ Dual-Core DSPs

Analog Devices Inc. ADSP-21591/ADSP-21593 SHARC+ Dual-Core DSPs are members of the single-instruction, multiple data (SIMD) SHARC family of digital signal processors (DSPs) that feature ADI Super Harvard Architecture. The ADSP-21591/ADSP-21593 DSPs are optimized for high-performance audio/floating-point applications with a large on-chip static random-access memory (SRAM), multiple internal buses that eliminate input/output (I/O) bottlenecks, and innovative digital audio interfaces (DAI). The devices are 32-bit, 40-bit, or 64-bit floating-point processors. Furthermore, the devices offer cache enhancements and branch prediction while maintaining instruction set compatibility with previous SHARC products.

The ADI ADSP-21591/ADSP-21593 SHARC+ Dual-Core DSPs integrate a set of industry-leading system peripherals and memory, ideal for applications that require programmability similar to reduced instruction set computing (RISC), multimedia support, and leading-edge signal processing in one package. These applications traverse many markets, including automotive, professional audio, and industrial-based applications that require high floating-point performance.
