ADSP-21362:高性能32位浮点SHARC处理器，适合汽车音频
The third generation of SHARC(R) Processors, which includes the ADSP-21261, ADSP-21262, ADSP-21266, ADSP-21267, ADSP-21363, ADSP-21364, ADSP-21365, and ADSP-21366, offers increased performance, audio and application-focused peripherals, and memory configurations capable of supporting surround-sound decoder algorithms. All devices are pin-compatible and completely code-compatible with all prior SHARC Processors. These members of the SHARC Processor family are based on a single-instruction, multiple-data (SIMD) core, which supports both 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats making them particularly suitable for high-performance audio applications.
The ADSP-21362 offers the highest performance – 333 MHz/2 GFLOPs -- within the third generation SHARC Processor family. This level of performance makes the ADSP-21362 particularly well suited to address the increasing requirements of the professional and automotive audio market segments. In addition to its higher core performance, the ADSP-21362 includes additional value-added peripherals such as an S/PDIF transmitter/receiver, 8-channel asynchronous sample rate converter, and a hardware Digital Transmission Content Protection (DTCP) encryption/decryption block.
Third generation SHARC Processors also integrate application-specific peripherals designed to simplify hardware design, minimize design risks, and ultimately reduce time to market. Grouped together, and broadly named the Digital Audio Interface (DAI), these functional blocks may be connected to each other or to external pins via the software-programmable Signal Routing Unit (SRU). The SRU is an innovative architectural feature that enables complete and flexible routing amongst DAI blocks. Peripherals connected through the SRU include but are not limited to serial ports, SPI ports, S/PDIF Tx/Rx, DTCP Accelerator, and an 8-Channel asynchronous sample rate converter block.
包括ADSP-21261、ADSP-21262、ADSP-21266、ADSP-21267、ADSP-21363、ADSP-21364、ADSP-21365及ADSP-21366在内的第三代SHARC(R)处理器可提供增强的性能、面向音频与应用的外设，以及能够支持环绕声解码器算法的存储器配置。所有器件均引脚兼容，并与以往的所有SHARC处理器完全代码兼容。这些SHARC处理器系列产品基于单指令多数据（SIMD）内核，支持32位定点以及32/40位浮点算法格式，特别适合高性能音频应用。在第三代SHARC处理器系列产品中，ADSP-21362具有333MHz/2GFLOPs的最高性能，这使得ADSP-21362特别适合于满足专业与汽车音频市场领域日益增长的需求。除了更高的内核性能外，ADSP-21362还提供其它增值外设，包括S/PDIF发送器/接收器、八通道异步采样速率转换器，以及硬件数字传输内容保护（DTCP）加密/解密模块。
第三代SHARC处理器还集成了专用外设，以简化硬件设计、减小设计风险，并最终缩短上市时间。组合在一起的功能模块被称作数字音频接口（DAI），这些功能模块可以互相连接，或通过软件编程的信号路由单元（SRU）连接到外部引脚。SRU是一种创新的架构特性，能够在DAI模块间实现完整且灵活的路由。通过SRU连接的外设包括但不限于串行端口、SPI端口、S/PDIF Tx/Rx、DTCP加速器，以及八通道异步采样速率转换器模块。
