ADI ADSP-215691GHz SHARC+DSP处理器开发方案

ADI公司的ADSP-21569是工作频率高达1GHz 的SHARC系列处理器,基于SHARC+®单核,是SIMD SHARC 数字信号处理器(DSP)系列产品,具有ADI超级哈佛架构(Super Harvard Architecture).这些32位/40位/64位浮点处理器具有高性能音频/浮点应用特性,集成了大容量SRAM,多个内部总线,从而解决了输入/输出(I/O)瓶颈障碍以及闯新的数字音频接口(DAI),SHARC+新增加的性能包括缓存增强和分支预测,而保留了和先前SHARC产品兼容的指令集功能.此外,器件还集成了业界一流的指令集和外设.因此,SHARC+处理器是需要相同于RISC的,多媒体支持以及单个封装内一流信号处理性能的可编性的应用平台最佳选择.具有广泛的应用市场包括汽车电子,专业音响和需要高浮点性能的工业应用.本文介绍了ADSP-21569处理器主要特性,处理器框图,SHARC+SIMD核框图以及ADZS-21569-EZKIT板主要特性,框图,电路图和材料清单.

Reaching speeds up to 1 GHz, the ADSP-2156x processors aremembers of the SHARC® family of products. The ADSP-2156xprocessor is based on the SHARC+® single core. The ADSP-2156x SHARC processors are members of the SIMD SHARCfamily of digital signal processors (DSPs) that feature AnalogDevices Super Harvard Architecture. These 32-bit/40-bit/64-bitfloating-point processors are optimized for high performanceaudio/floating-point applications with large on-chip static random-access memory (SRAM), multiple internal buses thateliminate input/output (I/O) bottlenecks, and innovative digitalaudio interfaces (DAI). New additions to the SHARC+ coreinclude cache enhancements and branch prediction, whilemaintaining instruction set compa
