ADI ADSP－21593 1GHz SHARC处理器音频开发方案

ADI公司的ADSP-2159x(ADSP-2159x/ADSP-SC59x)处理器运行速度可达1 GHz,属于SHARC®系列产品,是一款双核SHARC+® DSP,其音频性能为前代单核SHARC+ ADSP-2156x产品的两倍，同时在BGA封装中与其引脚兼容，提供400 MHz (ADSP-21566)至2 GHz (ADSP-21593)的设计可扩展性.ADSP-2159x SHARC处理器属于SIMD SHARC系列数字信号处理器(DSP),采用ADI公司的Super Harvard架构.这些32/40/64位浮点处理器针对高性能音频/浮点应用进行了优化,具有大容量片内静态随机存取存储器(SRAM),可消除输入/输出(I/O)瓶颈的多条内部总线,并且提供创新的数字音频接口(DAI).SHARC+内核最新加入的特性包括缓存增强和分支预测,同时保持指令集兼容之前的SHARC产品.处理器的存储器包括2048 KB 片内2级(L2) SRAM,具有ECC保护功能,在许多用例中无需外部存储器.16位DDR/DDR3L存储器控制器,DDR3L支持1.35V.主要用在汽车电子如音频放大器,音响主机,ANC/RNC,后部娱乐系统,数字座舱;消费类电子如AVR,混合控制台,麦克风阵列和会议系统.本文介绍了ADSP-2159x/ADSP-SC59x系统特性和特性表,ADSP-SC594(全特性模型)处理器框图,以及Arm Cortex-A5处理器框图,SHARC处理器框图,SHARC+SIMD核框图以及评估板EV-21593-SOM主要特性,框图,电路图和材料清单.

The ADSP-2159x/ADSP-SC59x processors are members of theSHARC® family of products. The ADSP-SC59x processors arebased on the SHARC+® dual-core and the Arm® Cortex®-A5core. The ADSP-2159x/ADSP-SC59x SHARC processors aremembers of the single-instruction, multiple data (SIMD)SHARC family of digital signal processors (DSPs) that featureAnalog Devices, Inc., Super Harvard Architecture. These 32-bit/40-bit/64-bit floating-point processors are optimized forhigh performance audio/floating-point applications with largeon-chip static random-access memory (SRAM), multiple internalbuses that eliminate input/output (I/O) bottlenecks, andinnovative digital audio interfaces (DAI). New additions to theSHARC+ core include cache enhancements and branch prediction,while maintaining instruction set compatibility to previousSHARC products.
