ADSP-21262 is a 32-bit highly integrated floating-point SHARC processor. Third generation SHARC processors also integrate audio-specific peripherals designed to simplify hardware design and 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 (IDP), precision clock generators (PCG) and timers. 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. The ADSP-21266 is a large memory, high-performance device targeted primarily at mid- to high-end home theater systems.
