Abstract: Systems and methods for delivering two data streams via two buses allow one of the buses to be used for delivering selected elements of the data stream that is primarily being delivered by the other bus. At an input rerouting circuit, the selected elements are rerouted from the second data stream into the first data stream; a token inserted in the second data stream identifies a position of the rerouted element. The modified streams are transmitted by the two buses. A receiving circuit reinserts the rerouted data element into the second data stream at the sequential position identified by the placeholder token.

Abstract: A computing system has a graphics processor, a graphics memory, main memory, a bridge, and a central processing unit configured to process floating-point data of a first fixed size. An interconnect grid includes communication paths to link the graphics processor, the graphics memory, main memory, the bridge, and the central processing unit. A computing system component (e.g., the graphics processor or central processing unit) converts floating-point data to graphics floating-point data with a fixed size smaller than the fixed size of the floating-point data. The computing system passes the floating-point data and/or the graphics floating-point data over at least a portion of the interconnect grid. Alternately, the graphics processor may directly read and process previously compressed and stored graphics floating-point data.
