Abstract
A data processing system includes a processor core having a store-through upper level cache and a store-in lower level cache. In response to a first instruction, the processor core generates a copy-type request and transmits the copy-type request to the lower level cache, where the copy-type request specifies a source real address. In response to a second instruction, the processor core generates a paste-type request and transmits the paste-type request to the lower level cache, where the paste-type request specifies a destination real address. In response to receipt of the copy-type request, the lower level cache copies a data granule from a storage location specified by the source real address into a non-architected buffer, and in response to receipt of the paste-type request, the lower level cache writes the data granule from the non-architected buffer to a storage location specified by the destination real address.
