Introduction to SHARC Processors

•Automotive audio applications. The ADSP-21362,ADSP-21365,ADSP-21369,ADSP-21371,ADSP-21462,ADSP-21465,ADSP-21469,ADSP-21472,ADSP-21475, and ADSP-21479 processors, with integration of sample-rate conversion, DTCP cipher, precision clock generators, and serial ports, are ideal choices for new multichannel automotive audio designs.

•Broad market use. SHARC processors are available in commercial, industrial, and automotive temperature grade packages. They are used in a wide variety of signal processing applications, providing up to 450 MHz performance in a single-instruction, multiple-data architecture (SIMD). Applications include imaging, medical devices, communications, military, test equipment, 3-D graphics, speech recognition, and motor control.

Architecture Overview

This section describes architectural features of the SHARC processor.

Super Harvard Architecture

The 32-bit floating-point SHARC processors from Analog Devices are based on a Super Harvard Architecture that balances exceptional core and memory performance with outstanding I/O throughput capabilities. This architecture extends the original concepts of separate program and data memory buses by adding an I/O processor with its associated dedicated buses.

In addition to satisfying the demands of the most computationally-inten- sive, real-time signal processing applications, SHARC processors integrate large memory arrays and application-specific peripherals designed to sim- plify product development and reduce time to market.
