1. A system for coordinated data execution in a computer system, comprising: a primary graphics processor coupled to a local graphics memory; an integrated graphics processor coupled to a system memory; a graphics bus coupling the primary graphics processor and the integrated graphics processor, wherein the primary graphics processor and the integrated graphics processor are configured for coordinated data execution via communication across the graphics bus and for selectively allocating a first portion of graphics processing operations to the primary graphics processor and a second portion of graphics processing operations to the secondary graphics processor for execution to render a 3-D display, and wherein the integrated graphics processor is allocated transform and lighting operations, and wherein the secondary graphics processor utilizes a high communications bandwidth with system memory to implement texture map reordering, texture compression, decryption and decoding of video.
