ABSTRACT:
A data processing system for supporting a virtual memory is disclosed. Prior to the start of main memory write operation, a processor checks to see if a store buffer has a vacant area to store data to be written into a main memory to execute a current instruction. If a page fault occurs during the main memory write operation, the processor continues to store the subsequent write data for the current instruction and the corresponding virtual or logical addresses in the store buffer to complete execution of the current instruction.
