　　The ADSP-SC58x/ADSP-2158x processors are members of theSHARC® family of products. The ADSP-SC58x processor isbased on the SHARC+ dual-core and the ARM Cortex-A5 core.

　　The ADSP-SC58x/ADSP-2158x SHARC processors are membersof the SIMD SHARC family of 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 their large on-chipSRAM, multiple internal buses to eliminate I/O bottlenecks, andinnovative digital audio interfaces (DAI). New nhancements tothe SHARC+ core add cache enhancements, branch prediction,and other instruction set improvements—all while maintaininginstruction set compatibility to previous SHARC products.

　　By integrating a rich set of industry-leading system peripheralsand memory, theARM/SHARC processor is the platform of choice for next-generationapplications that require RISC-like programmability,multimedia support, and leading-edge signal processing in oneintegrated package. These applications span a wide array ofmarkets, from automotive and pro-audio to industrial-basedapplications that require high floating-point performance.

　　ADSP-SC589 EZ-KIT Lite和EZ-Board评估板

　　ADSP-SC589 EZ-KIT Lite和EZ-Board®是针对ADSP-SC58x系列SHARC®处理器的评估系统。 ADSP-SC589处理器基于具有ARM® Cortex-A5™处理器内核的SHARC+™双核处理器，适合众多市场领域，从汽车和专业音频到需要高浮点性能的工业应用。 EZ板附带所有必要的硬件，可立即评估。此封装包含独立的评估板、通过CE认证的电源和USB电缆。 EZ-KIT Lite®版本提供用于CrossCore® Embedded Studio (CCES)和ICE-1000仿真器的两个180天许可，同时EZ板版本需要客户提供ICE-1000或ICE-2000仿真器。

　　扩展接口III连接器可与其他扩展板接口以提供LCD、摄像机、视频和音频。采用I2C控制软件开关可消除用于更改电路板出厂设置的传统机械开关。唯一剩下的机械开关包括引导模式开关、JTAG配置开关和按钮。

　　本评估板可与CrossCore® Embedded Studio (CCES)开发工具配合使用，以测试ADSP-SC58x处理器的功能。该开发环境有助于先进应用代码开发和调试，例如：

　　创建、汇编、组装和链接采用C++、C和汇编语言编写的程序

　　在应用程序中加载、运行、步进、停止和设置断点

　　读写数据和程序内存

　　读写内核和外设寄存器

　　Thank you for purchasing the ADSP-SC589 EZ-Board®, Analog Devices, Inc. evaluation system forthe ADSP-SC58x family of SHARC® processors.

　　The ADSP-SC589 processor is based on the SHARC+™ core dual processor with the ARM® Cortex-A5™ processor core and is designed for a wide array of markets, from automotive and pro-audio toindustrial-based applications that require high floating-point performance. The EZ-Board is shippedwith all of the necessary hardware—you can start the evaluation immediately. The package containsthe standalone evaluation board, CE-approved power supply, and USB cable. The EZ-KIT Lite®version ships with the ICE-1000 emulator, while the EZ-Board version requires the customer toprovide an ICE-1000 or ICE-2000 emulator.

　　Expansion Interface III connectors are provided for interfacing with additional extender boards toprovide LCD, camera, video, and audio.

　　Traditional mechanical switches for changing the board’s factory setup have been removed in favor ofI2C controlled software switches. The only remaining mechanical switches are the boot mode switch,JTAG configuration switches, and push buttons.

　　The evaluation board is designed to be used in conjunction with the -CrossCore® Embedded Studio(CCES) development tools to test capabilities of the ADSP-SC58x processors. The developmentenvironment aids 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
