Abstract
The present invention provides a mechanism for implementing z-compression in a manner that is transparent to the user. Blocks of z-data are associated with storage locations in a z-data buffer in cleared, compressed, or uncompressed data states. Operations to the z-data buffer are monitored for selected operations. These operations may include clear or lock operations. If a selected operation is detected, a modified version of the selected operation is implemented to mask differences between the storage states of the data blocks.
