原标题：ADI ADSP-SC57xSHARC双核处理器开发方案

　　ADI公司的ADSP-SC57x/2157x系列处理器集成了两个增强型SHARC+®内核和先进的DSP加速器(FIR,IIR),功耗低于2W,功效比以前的SHARC产品高5倍以上,专为需要DSP协处理器并包括两个SHARC+内核和一个匹配DSP内核的外设集的应用而设计,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-SC57x/ADSP-2157x系统特性,处理器框图,ARM Cortex-A5处理器器框图,SHARC处理器框图,SHARC+SIMD处理器核框图以及评估板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.

　　By integrating a set of industry leading system peripherals andmemory, the ARM Cortex-A5 and SHARC processor is the platform of choice for applicationsthat require programmability similar to reducedinstruction set computing (RISC), multimedia support, andleading edge signal processing in one integrated package. Theseapplications span a wide array of markets, including automotive,professional audio, and industrial-based applications thatrequire high floating-point performance.

　　Thank you for purchasing the Analog Devices, Inc. ADSP-SC573 EZ-KITevaluation system.

　　The ADSP-SC573 processor is a members of the SHARC® family of products. The ADSP-SC573 processor isbased on the SHARC+ dual-core and the ARM® Cortex-A5TM core. The ADSP-SC573SHARC processor is amembers of the SIMD SHARC family of DSPs that feature Analog Devices Super Harvard Architecture. These 32-bit/40- bit/64-bit floating-point processors are optimized for high performance audio/floating-point applicationswith their large onchip SRAM, multiple internal buses to eliminate I/O bottlenecks, and innovative digital audiointerfaces (DAI). New enhancements to the SHARC+ core add cache enhancements, branch prediction, and otherinstruction set improvements—all while maintaining instruction set compatibility to previous SHARC products.

　　The EZ-KIT ships with all of the necessary hardware to get you up and running and start the evaluation immediately.

　　The EZ-KIT contains an expansion interface 3 (EI3). This interface provides for connecting with daughter boardsto expand on the functionality of the EZ-KIT.

　　The evaluation board is designed to be used in conjunction with the CrossCore Embedded Studio® developmentenvironment for advanced application code development and debug such as:

　　• Create, compile, assemble, and link application programs written in C++, C, and assembly

　　• Load, run, step, halt, and set breakpoints in application programs

　　• Read and write data and program memory

　　• Read and write core and peripheral registers
