Abstract (en)

[origin: WO2007001257A1] A cache (120) is adapted to be coupled to a bus (116) and includes an array (125) and a controller (122). The array (125) has a plurality of sets (200, 210, 220) each having a plurality of cache lines (202), each cache line in each set including a tag and a plurality of data words. The controller (122) is coupled to the array (125), and associates both a first portion (205) of the plurality of cache lines (202) of each set with a first bus operation type and a second portion (206) of the plurality of cache lines (202) of each set with a second bus operation type according to a configuration value (232, 234). The controller (122) also causes data conducted over the bus (116) during a bus operation to be selectively stored in the first portion (205) if a type of the bus operation is the first bus operation type or in the second portion (206) if the type of the bus operation is the second bus operation type.
