adsp-21489 高性能第四代DSP

SHARC ADSP-21489是第四代SHARC®处理器系列的两款新产品之一，该系列目前包括： ADSP-21483、ADSP-21486、ADSP-21487、ADSP-21488、具有更高的性能，提供硬件型滤波器加速器、音频和应用专用外设，其新型存储器配置可支持最新环绕声解码器算法。所有器件均相互引脚兼容，且与以前的所有SHARC处理器全代码兼容。第四代SHARC处理器系列的这些最新成员基于一款单指令多数据(SIMD)内核制成，支持32位定点和32/40位浮点算法格式，是高性能音频应用的理想选择。

ADSP-21489提供最高性能——450 MHz/2700 MFLOP——采用LQFP封装，是第四代SHARC处理器系列中的一员。这一性能水平使ADSP-21489成为汽车音频和工业控制应用的理想之选。 ADSP-21489不但拥有较高的内核性能，而且内置了FIR、IIR和FFT加速器等额外的处理模块，可以大幅提升系统的整体性能。可变指令集架构(VISA)是其特色新功能之一，可使代码减少20%至30%，从而提高存储器的可用性。第四代DSP为16位宽SDR SDRAM提供了一个无缝接口，可以连接外部存储器。

第四代SHARC处理器同时集成应用专用外设，有利于简化硬件设计、减少设计风险并最终缩短上市时间。这些功能模块被称为数字应用接口(DAI)，可以相互连接，也可连接通过软件可编程信号路由单元(SRU)连接至外部引脚。 SRU是一种新型架构，可在DAI模块间实现完全、灵活路由。可通过SRU连接的外设包括但不限于串行端口、IDP、S/PDIF Tx/Rx和8通道异步采样速率转换器模块。第四代SHARC可将来自串行端口的数据通过DMA控制器直接传输到外部存储器。 SPI、UART、双线接口等其他外设通过数字外设接口(DPI)路由。
