Abstract
A secondary cache controller, a method of operating a secondary cache and a secondary cache incorporating the controller or the method. In one embodiment, the controller includes: (1) configuration registers that allow at least one cacheable memory range to be defined and (2) a standard bus interface that cooperates with the configuration registers to allow the secondary cache controller to operate in: (2a) a configuration mode in which values are written to the configuration registers via only the standard bus interface to define the at least one cacheable memory range and (2b) an operating mode in which the values govern operation of the secondary cache controller absent external cache control instructions.
