Abstract
A system (10) uses shared resources (44, 54) to perform conventional load/store operations, to preload custom data from external sources, and to efficiently manage error handling in a cache (42, 52, 48). A reload buffer (44, 54) is used in conjunction with a cache (42, 52) 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 (70) selectively enables the pushing of data into the cache (42, 52, 48) from an external source. The control signal utilizes one or more attribute fields that provide functional information and define memory characteristics.
