A system () uses shared resources () to perform conventional load/store operations, to preload custom data from external sources, and to efficiently manage error handling in a cache (). A reload buffer () is used in conjunction with a cache () operating in a write-through mode to permit lower level memory in the system to operate in a more efficient write-back mode. A control signal () selectively enables the pushing of data into the cache () from an external source. The control signal utilizes one or more attribute fields that provide functional information and define memory characteristics.

System and method for cache external writing

A system provides a method and apparatus for accessing information in a cache in a data processing system. The system optimizes a speed-critical path within the cache system by using a prediction scheme. The prediction scheme subdivides the address range of address bits and compares the portions separately. A comparison of a critical portion of the address, along with a prediction bit, are used to generate a prediction.
