  • Patent number: 7337372
    Abstract: Multi-hit errors in a processor cache are detected by a multi-hit detection circuit coupled to the hit lines of the cache. The multi-hit detection circuit compares pairs of hit signals on the hit lines to determine if any two hit signals both indicate a hit. If multiple hits are detected, an error flag indicating the occurrence of multiple hits is generated.

  • Patent number: 7089360
    Abstract: In one embodiment, a wordline decoder provides access to cache memory locations when addresses are bypassed directly from arithmetic circuitry in redundant form. The wordline decoder is also designed to provide access to cache memory locations when addresses are received from registers in an unsigned binary form. The combined functionality is provided in a pre-decode circuit by selectively replacing one of a plurality of redundant bit vectors with a constant bit vector when redundant addressing is not enabled.

  • Patent number: 6862225
    Abstract: A novel buffer design including a differential driver circuit provides an improved overall performance to a microprocessor by reducing the number of cycles required by the microprocessor to access data from a cache memory during a split cache line access. In one embodiment of the present invention, when a request to access data from a cache memory comes from a microprocessor, during a first cycle, a first sense amplifier coupled to the cache memory senses a first cache line from the cache memory. Then a first input driver circuit coupled to the first sense amplifier receives the sensed first cache line and stores the first cache line in a split buffer. Then the first sense amplifier senses a second cache line from the cache memory. Then a second sense amplifier coupled to the split buffer senses the stored first cache line from the split buffer.
