1 GHz SHARC+ DSP with 2048KB Shared L2 SRAM

Reaching speeds of up to 1 GHz, the ADSP-21568 processors are members of the SHARC® family of products. These processors offer a cost-reduced pin- and code-compatible option to the ADSP-21566/ADSP-21567/ADSP-21569 processors, while offering double the L2 memory (2MB) and supporting the peripheral functions of the ADSP-21562/ADSP-21563/ADSP-21565 LQFP package products.

The processors are members of the SIMD SHARC family of digital signal processors (DSPs) that feature Analog Devices, Inc., 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). 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, the 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.
