Abstract: An insulating structure comprises two beams (70), each having a longitudinally extending connecting means (90) and upper and lower flanges (76, 78) arranged such that a channel is defined along two opposing sides of the beam (70) between the connecting means (90) and the upper and lower flanges (76, 78); and an elongate body of insulating material (72); wherein a first side of the body is engaged along the length of one of the beams (70) in one of the channels thereof and an opposite second side of the body (72) is engaged along the length of the other of the beams (70) in one of the channels thereof.

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.
