ADI ADSP－SC573 SHARC+处理器开发方案
ADI公司的ADSP-SC57x/2157x系列处理器是新型高性能高效实时系列的一部分,集成两个增强型SHARC+®内核和先进的DSP加速器(FIR,IIR),功耗低于2瓦,高达450 MHz per SHARC+核和ARM Cortex-A5核,主要用在汽车,消费电子和专业音频,多轴电机控制和能源分配系统.本文介绍了ADSP-SC573主要特性,功能框图,ARM Cortex-A5处理器核框图,SHARC处理器核框图,SHARC+SIMD核框图以及评估板ADSP-SC573 EZ-KIT主要特性,框图,电路图和材料清单.
The ADSP-SC57x/ADSP-2157x processors are members of theSHARC® family of products. The ADSP-SC57x processor isbased on the SHARC+® dual-core and the ARM® Cortex®-A5core. The ADSP-SC57x/ADSP-2157x SHARC processors aremembers of the single-instruction, multiple data (SIMD)SHARC family of digital signal processors (DSPs) that featureAnalog Devices Super Harvard Architecture. These 32-bit/40-bit/64-bit floating-point processors are optimized for high performanceaudio/floating-point applications with large on-chipstatic random-access memory (SRAM), multiple internal busesthat eliminate input/output (I/O) bottlenecks, and innovativedigital audio interfaces (DAI). New additions to the SHARC+core include cache enhancements and branch prediction, whilemaintaining instruction set compatibility to previous SHARC products.
