Abstract

An improved cache memory for use with a microprocessor. A line buffer which stores a tag and offset field and the corresponding line of data is employed. Valid bits are associated with different potions of the data stored in the line buffer. Thus during a line fill, by way of example, an instruction may be read from the line buffer before the entire line is filled from main memory.
