Abstract
A shader having a cache memory for storing program instructions is described. The cache memory beneficially stores both current programming instructions for a fragment program being run and 'look-ahead' programming instructions. The cache memory supports a scheduler that forms program commands that control programmable processing stations. The cache memory can store multiple programming instructions for a plurality of shaders. If the cache memory does not include the desired programming instructions, a miss is asserted and a scheduler (instruction processor) recovers the programming instructions to be run. Beneficially, the scheduler recovers additional programming instructions to support the look-ahead programming. The cache memory stores program instructions by cachelines, where each cacheline comprises a plurality of programming instructions. The cache memory can also store program identifiers.
