ADSP-21375:32位高性能浮点SHARC处理器
ADSP-21375 SHARC(R)处理器针对多种应用可提供最高的MFLOP性能。ADSP-21375器件与其它SHARC处理器如ADSP-21367和ADSP-21369在引脚和代码方面兼容。这种SHARC处理器基于一个单指令多数据（SIMD）内核，支持32位定点和32/40位浮点运算格式，使它们特别适合于成本得到优化的高精密性应用。
SHARC处理器还集成了许多外设，旨在简化硬件设计，最大限度地减少设计风险，并最终缩短上市时间。这些功能模块组合起来，加上广为人知的数字应用 接口（DAI），通过软件可编程的信号路由单元（SRU）可以彼此连接或连接至外部引脚。SRU是一个创新的架构特性，可以在DAI模块之间实现完整而灵活的路由。通过SRU连接的外设包括但不限于：串行接口、SPI端口模块。
The ADSP-21375 SHARC(R) Processor family offers the highest MFLOP/$ performance for a variety of applications. The ADSP-21375 device is pin-compatible and code-compatible with prior SHARC Processors such as the ADSP-21367 and ADSP-21369. This member of the SHARC Processor family is 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 cost optimized high precision applications.
SHARC Processors also integrate many peripherals designed to simplify hardware design, minimize system design risks, and reduce end-customer time to market. Grouped together, and broadly named the Digital Applications 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 and SPI ports block.
