ADI ADSP－21375 32位SHARC处理器开发评估方案
ADI公司的ADSP-21375是高性能 32位浮点SHARC处理器,采用ADI公司的超哈佛架构,SIMD计算架构,工作频率266MHz,集成了众多的音频外设如数字应用接口,S/PDIF收发器,串行端口,精密时钟发生器等.主要用在工业控制,仪器仪表,医疗电子以及专业音响等领域.本文介绍了ADSP-21375主要特性, 功能方框图和HARC核方框图,以及ADSP-21375 EZ-KIT Lite®评估板主要特性, 系统框图, 电路图和材料清单.
The ADSP-21371/ADSP-21375 SHARC® processors are members of the SIMD SHARC family of DSPs that feature Analog Devices’ Super Harvard Architecture. The processors are source code compatible with the ADSP-2126x, ADSP-2136x, and ADSP-2116x DSPs, as well as with first generation ADSP-2106x SHARC processors in SISD (single-instruction, single-data) mode. The processors are 32-bit/40-bit floating-point processors optimized for high performance automotive audio applications with their large on-chip SRAM and mask-programmable ROM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital applications interface (DAI).
