Featured Products
ADSP-21569

Reaching speeds up to 1GHz, the ADSP-2156x processors are members of the SHARC® family of products. The ADSP-2156x processor is based on the SHARC+® single core. The ADSP-2156x SHARC processors are members of the SIMD SHARC family of digital signal processors (DSPs) that feature Analog Devices 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 rich set of industry-leading system peripherals and memory (see Table 1 on the datasheet), the SHARC+ processor is the platform of choice for applications that require programmability similar to RISC (reduced instruction set computing), multimedia support, and leading-edge signal processing in one integrated package. These applications span a wide array of markets, including automotive, pro audio, and industrial-based applications that require high floating-point performance.
