ABSTRACT:
A method for retrieving compressed texture data from a memory system while conserving bus bandwidth and memory bandwidth is disclosed. The method is particularly useful when the compressed texture data sought to be retrieved is stored in memory in the form of blocks that have varying lengths. A starting address is determined for a target compressed texture data segment stored in the memory. The target compressed segment contains a compressed data block which in turn contains a compressed representation of the texture data sought to be retrieved. A read request issuance operation is commenced, beginning with the starting address of the target segment. Various techniques are disclosed for stopping the read request issuance operation once it is determined that sufficient read requests have been issued to retrieve a complete compressed representation of the texture data of interest.
