Abstract: A Hard Disk Drive (HDD) is provided two FATs and two cluster sizes, a regular cluster and a “Supercluster”. In one example, each Supercluster is the size of four regular clusters. A second Supercluster FAT is added (FAT2) which works in a similar manner to the original FAT (hereinafter FAT1), but instead points to the next Supercluster in the chain. Since there are far fewer Superclusters than clusters, the Supercluster FAT (FAT2) can be stored in a cache memory. When data is streamed to and from the hard drive, it can be streamed to Superclusters and no seeks on the HDD to a FAT are required, as the FAT2 is cached in memory. Access time to and from the hard drive is decreased. The original cluster configuration is still supported. During lulls in system operation, the FAT2 data may be written to the drive and moreover, FAT1 data created and “flushed” to the hard drive.

Abstract: A caching system for increasing the operation concurrency between a cache module and a memory module by comparing received memory block identifiers, which correspond to texels needed for pixel composition, with memory block identifiers corresponding to texels locally stored within the cache module. If the received memory block identifiers match the memory block identifiers corresponding to locally cached texels, the system transmits these texels to a texture filter unit for pixel composition. If the received memory block identifiers do not match memory block identifiers corresponding to the locally cached texels, the system retrieves these texels from the memory module as fast as possible and then updates the cache module with the new texels. A plurality of first in, first out buffers are used to assist a controller module with synchronizing the transmission of the texels from the cache module and the overwriting of the texels received from the memory module into the cache module.
