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
