Techniques for transferring graphics data from system memory to a discrete GPU

摘要

A method for transferring graphics data includes receiving graphics data in the system memory. The graphics data may be loaded into system memory by and application from a mass storage device. One or more graphics commands associated with the graphics data may also be received. The graphics commands may also be received from the application. The graphics data in system memory is compressed in response to receipt of the one or more graphics commands before the graphics data is transferred to a discrete graphics processing unit. The one or more received graphics commands are transferred to the discrete graphics processing unit. The one or more graphics commands include an operation to copy the compressed graphics data to the discrete graphics processing unit. The compressed graphics data is copied from the system memory to memory of the graphics processing. The compressed graphics data is then decompressed by the graphics processing unit. Thereafter, the discrete graphics processing unit may perform one or more graphics operations on the transferred graphics data.
