Abstract
A computer system ( ) comprising a central processing unit ( ) and a memory hierarchy. The memory hierarchy comprises a first cache memory ( ) and a second cache memory ( ). The first cache memory is operable to store non-pixel-information, wherein the non-pixel information is accessible for processing by the central processing unit. The second cache memory is higher in the memory hierarchy than the first cache memory, and has a number of storage locations operable to store non-pixel information ( ) and pixel data ( ). Lastly, the computer system comprises cache control circuitry ( ) for dynamically apportioning the number of storage locations such that a first group of the storage locations are for storing non-pixel information and such that a second group of the storage locations are for storing pixel data.
