ADSP-21365: 面向汽车音频的高性能32位浮点SHARC处理器
成员包括ADSP-21262、ADSP-21266、ADSP-21267、ADSP-21364和ADSP-21365的第三代SHARC(R)处理器系列提供了更优越的性能、更注重音频功能与应用的外设、以及能够支持最新环绕声解码器算法的新型存储器配置。这些器件均与先前推出的全部SHARC处理器引脚兼容及代码全兼容。这些SHARC处理器系列的最新成员基于一个单指令、多数据（SIMD）内核，（该内核支持32位定点和32/40位浮点算术格式），从而使其成为高性能音频应用的绝佳选择。
在第三代SHARC处理器系列中，ADSP-21365提供了最高的性能 —— 300MHz/1800MFLOPs。这种性能水平使得ADSP-21365尤其适合于满足专业音频和汽车音频专业市场不断提高的要求。除了其较高的内核性能之外，ADSP-21365还包括附加的增值外设，比如一个S/PDIF发送器/接收器、8通道异步采样频率转换器和一个硬件数字传输内容保护（DTCP）加密/解密模块。
第三代SHARC处理器还集成了专为简化硬件设计、实现设计风险的最小化并最大限度地缩短产品面市时间的专用外设。这些功能模块组合在一起（统称为数字音频接口，DAI），可以彼此相连，也可以通过软件可编程信号路由单元（SRU）连接至外部引脚。SRU是一种创新型架构特点，可在DAI模块之间实现全面而灵活的路由。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加速器和一个8通道异步采样频率转换器模块。
The third generation of SHARC(R) Processors, which includes the ADSP-21261, ADSP-21262, ADSP-21266, 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-21365 offers the highest performance – 333 MHz/1800 MFLOPs -- within the third generation SHARC Processor family. This level of performance makes the ADSP-21365 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-21365 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.
