ADSP-21364:面向专业音频的高精度32位浮点SHARC处理器
The third generation of SHARC(R) Processors, which includes the ADSP-21262, ADSP-21266, ADSP-21267, ADSP-21364, and ADSP-21365, offers increased performance, audio and application-focused peripherals, and memory configurations. 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-end audio applications.
The ADSP-21364 offers the highest performance – 333MHz/2GFLOPs -- within the third generation SHARC Processor family. This level of performance makes the ADSP-21364 particularly well suited to address the increasing requirements of the professional audio market segment. High core performance combined with audio centric peripherals including a high-precision, 8-channel asynchronous sample rate converter makes the ADSP-21364 a very good choice in applications requiring industry-leading equalization, reverberation, and other effects processing.
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, an Input Data Port, precision clock generators, and a high-precision 8-channel asynchronous sample rate converter functional block. This flexibility of resource utilization combined with the ease of use of the SHARC Processor programming model allow manufacturers to leverage a single hardware design for multiple products with varying I/O requirements.
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、注重于音频功能与应用的外设以及新型存储器配置。这些器件均与先前推出的所有SHARC处理器引脚兼容并实现了代码全兼容。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），从而使其成为高端音频应用的绝佳选择。
在第三代SHARC处理器系列中，ADSP-21364提供了最高的性能 —— 300MHz/1800MFLOPs。这种性能水平使得ADSP-21364尤其适合于满足专业音频区段专业市场不断提高的要求。高内核性能，再加上以音频为中心的外设（包括一个高精度、8通道异步采样率转换器），使得ADSP-21364成为那些需要业界领先的均衡、混响及其他音效处理的应用的极佳选择。
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以及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（被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部件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、一个输入数据端口、精确时钟发生器和一个高精度8通道异步采样率转换器功能模块。这种资源利用的灵活性，再加上SHARC处理器编程模型的易用性，使得制造商能够将一种硬件设计应用于多种具有不同I/O要求的产品中。
