1. SHARC DSPs SHARC is a DSP architecture designed and fabricated by Analog Devices, Inc. As of Spring 2005, they manufacture and sell 22 DSPs based on the SHARC Price is $10/unit (qty 10,000) - $200/unit

2. SHARC features Common features include: –32/40-bit IEEE floating point math –No arithmetic pipeline (single cycle exec) –Circular buffer addressing in hardware –Six nested levels of zero-overhead looping –ISA has several DSP specific operations –DMA allows zero-overhead background transfer for sustained memory access

3. SHARC features Varied features include: –Clock speed (40-400MHz), package type –MMACs (40-800) –Voltage (1.2-5v) –On-chip ROM (0-16 Mbits) and SRAM (0.5-16 Mbits) –Ports (serial, SPDIF, DAI) –Sample rate converters

4. SHARC ISA Instruction set includes: –Min, max, clip operations –Abs operations –Up to 3 inst/word (MAC, MAA, etc.) –Post-increment and looped addressing –Saturation arithmetic
