Abstract
A graphics accelerator includes a plurality of digital signal processors that are arranged in a self-regulating, peer-to-peer configuration. Accordingly, the processors cooperate to process, on a cyclical basis, each of a successive series of graphics requests received over a request bus. To that end, each processor includes a request bus, an input in communication with the request bus, and an output coupled to a sequencer for ordering graphics requests processed by the digital signal processors.
