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.

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 member 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
