Method and apparatus for isolating faulty semiconductor devices in a multiple stream graphics system

摘要

A method and an apparatus are provided for isolating faulty semiconductor devices in a multiple stream graphics system. The apparatus includes a buffer adapted to receive a plurality of data streams. The apparatus further includes a convolver comprising at least one convolution signature register; a router adapted to route the data streams from the buffer to the convolver, wherein the router comprises at least one router signature register; and an analyzer adapted to access the convolution and router signature registers, wherein the analyzer is capable of isolating at least one of a faulty semiconductor device and a faulty interconnection using the contents of the convolution and router signature registers.
