    摘要: 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.

    摘要: The present invention is directed to a method and apparatus for exposing pre-diffused IP blocks in a semiconductor device for prototyping based on hardware emulation. Addresses may be provided to multiplexers through configuration pins. The input ports of the multiplexers may be connected to interface pins of the pre-diffused IP blocks, and the output ports of the multiplexers may be connected to I/O pins which provide input and output to the semiconductor device. Through controlling the signals on the configuration pins and thus the outputs of multiplexers, any single pre-diffused IP blocks or any combination of the pre-diffused IP blocks in the semiconductor device may be exposed through corresponding I/O pins for prototyping.
