Getting Started With SHARC Processors 1-3
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.
