ADSP-21364:  High Precision 32-Bit Floating-Point SHARC Processor for Professional Audio

Product Description

The third generation of SHARC® 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.
