Abstract
A cache memory ( ) has a logical organisation in which its memory space is divided into sub-sections or partitions (P). This permits different data objects to be allocated to different partitions during the operation of the cache memory ( ). Commands led used by the cache memory ( ) may contain an extra parameter which is used to identify the appropriate partition within the cache memory ( ). The parameter is extracted from the command by a decoder ( ) and is passed to a specific line of an equator set ( ) which contains identifiers which determine the partition to be used. To minimise data collisions for a given partition size, a stride may be defined which expresses the separation of addresses and from which a mapping function can be selected which covers all addresses in the cache memory ( ) in an efficient way.
