Abstract
PURPOSE: To make it possible to process an error by making a reproduction of a write address having been lost, by reporting an error address in write error generation by making use of a buffer invalidation address bus.
CONSTITUTION: Once access requesting original unit 1-0 sends a write request, memory access controller 2 accepts the request and starts write operation for memory 3 and at the same time, unit 2 transfers buffer invalidation address BIA to other access requesting original units 1-1W1-3. Next, since unit 2 never transfers BIA to unit 1-0 at this timing, the attention is paid to this to let unit 2 report [write-error-possible address] to unit 1-0 via BIA bus 6-0. Then, the possible address is held in unit 1-0 and when unit 2 generates an error in write operation actually, the generation is reported to unit 1-0. When no error occurs, the held possible address is erased.
