ADSP-21566/21567/21569 GENERAL DESCRIPTION
Reaching speeds of up to 1 GHz, the ADSP-2156x processors SHARC+ core include cache enhancements and branch predic- are members of the SHARC® family of products. The ADSP- tion, while maintaining instruction set compatibility to previous 2156x processor is based on the SHARC+® single core. The SHARC products. ADSP-2156x SHARC processors are members of the SIMD By integrating a rich set of industry-leading system peripherals SHARC family of digital signal processors (DSPs) that feature and memory (see Table 1), the SHARC+ processor is the plat- Analog Devices, Inc., Super Harvard Architecture. These 32- form of choice for applications that require programmability bit/40-bit/64-bit floating-point processors are optimized for similar to reduced instruction set computing (RISC), multime- high performance audio/floating-point applications with large dia support, and leading edge signal processing in one on-chip static random-access memory (SRAM), multiple inter- integrated package. These applications span a wide array of nal buses that eliminate input/output (I/O) bottlenecks, and markets, including automotive, professional audio, and indus- innovative digital audio interfaces (DAI). New additions to the trial-based applications that require high floating-point performance.
