# Analog Devices DSP Processors

Notes by Prof. Brian L. Evans

There are only three floating-point DSP families on the market today: Analog Devices SHARC, Texas Instruments C3000, and Texas Instruments C6700.

# SHARC

Analog Devices has announced a higher clock speed of 250 MHz for their floating-point programmable DSP known as the Super-Harvard Architecture (SHARC):

"At a 250 MHz clock rate, the ADSP-TS101S [TigerSHARC] offers a DSP industry-best 1500 MFLOPS peak performance and has native support for 8, 16, 32, and 40-bit data types. With a 1.5 watt typical power dissipation, 6 Mbits of on-chip memory, 14 channel zero-overhead DMA engine, integrated SDRAM controller, parallel host interface, cluster multiprocessing support, and link port multiprocessing support, the TigerSHARC is ideal for heat sensitive multiprocessing applications."

Here are some of the target applications for floating-point DSPs:

"TigerSHARC's exceptional speed and functionality are suited for applications in:
Defense - sonar, radar, digital maps, munitions guidance
Medical - ultrasound, CT scanners, MRI, digital X-ray
Industrial systems - data acquisition, control, test, and inspection systems
Video processing - editing, printers, copiers
Wireless Infrastructure - GSM, EDGE, and 3G cellular base stations."
