Abstract
A hardware implemented method for writing data to a cache is provided. In this hardware implemented method, a Block Initializing Store (BIS) instruction is received to write the data from a processor core to a memory block. The BIS instruction includes the data from the processor core. Thereafter, a dummy read request is sent to a memory controller and known data is received from the memory controller without accessing a main memory. The known data is then written to the cache and, after the known data is written, the data from the processor core is written to the cache. A system and processor for writing data to the cache also are described.
