  • Microprocessor with on-chip cache memory with lower power consumption
    Patent number: 5018061
    Abstract: A microprocessor with on-cache memory and an address translation buffer in which it further comprises first and second flip-flop circuits for indicating in hit or miss in the tag field of the cache memory and for storing which of the X and Y sections of the tag field a target data exists. Access to the tag field is carried out prior to access to the data field of the cache memory, thereby preventing access to the data field when a miss occurs in the tag field, and thus decreasing power consumption.
