A 1.5 GIPS video signal processor (VSP)

摘要

A general purpose, programmable, digital video signal processor has been designed for efficient processing of real-time video signals. The chip is fabricated in a 0.8 /spl mu/m CMOS technology on a die of 156 mm/sup 2/. The parallel architecture of 28 processing elements realizes a throughput of 15 GIPS at a clock-frequency of 54 MHz. To achieve such a throughput, many of the blocks are custom designed. Special attention has been given to clock routing. Dedicated measures have been taken to reduce power and ground bounce. One of them is the inclusion of a low-voltage I/O mode, which also limits the power consumption. A set of programming tools supports the development of applications.
