GENERAL DESCRIPTION

Reaching speeds of up to 1 GHz, the ADSP-2156x processorsare 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 SIMDSHARC family of digital signal processors (DSPs) that featureAnalog Devices, Inc., Super Harvard Architecture. These 32-

bit/40-bit/64-bit floating-point processors are optimized forhigh performance audio/floating-point applications with largeon-chip static random-access memory (SRAM), multiple inter

nal buses that eliminate input/output (I/O) bottlenecks, andinnovative digital audio interfaces (DAI). New additions to theSHARC+ core include cache enhancements and branch predic

tion, while maintaining instruction set compatibility to previous

SHARC products.

By integrating a rich set of industry-leading system peripheralsand memory (see Table 1), 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 oneintegrated package. These applications span a wide array of

markets, including automotive, professional audio, and industrial-based applications that require high floating-pointperformance.
