Abstract: The snoop controller generates control signal necessary for cache coherence protocol according to address signals related to memory cycle within one period of timer pulse. The controller includes a write address comparators (2-5) for comparing bus address signal with write back address signal detected at every rising edge of control signal to generate write address match signal, read address comparators (10-13) for comparing bus address signal with read address signal detected at every vising edge of timing pulses to generate read address match signal, a first program enable memory (15) for generating bus parity error signal and acting signal according to bus address space signal, bus address enable signal, and snoop action stop signal, a second program enable memory (16) for generating write back going signal and a third program enable memory (17) for generating state memory write enable signal and data input signal.
