ADI ADSP-21584CBCZ-4A

The ADSP-SC58x/ADSP-2158x processors are members of the SHARC family of products. The ADSP-SC58x processor is based on the SHARC+ dual core and the Arm Cortex-A5 core. The ADSP-SC58x/ADSP-2158x SHARC processors are members of the SIMD SHARC family of digital signal processors (DSPs) that feature Super Harvard Architecture. These 32-bit/40-bit/64-bit floating-point processors are optimized for high performance audio/floating-point applications with large, on-chip, static random-access memory (SRAM), multiple internal buses that eliminate input/output (I/O) bottlenecks, and innovative digital audio interfaces (DAI). New additions to the SHARC+ core include cache enhancements and branch prediction, while maintaining instruction set compatibility to previous SHARC products.

By integrating a set of industry leading system peripherals and memory, the Arm Cortex-A5 and SHARC processor is the platform of choice for applications that require programmability similar to reduced instruction set computing (RISC), multimedia support, and leading edge signal processing in one integrated package. These applications span a wide array of markets, including automotive, professional audio, and industrial-based applications that require high floating-point performance.
