PURPOSE:To simplify the hardware and the memory command, by locating a lock/unlock circuit at a processor side. CONSTITUTION:A processor 1 is provided with a lock line 5 being a common signal line tying processors in addition to an interface 3 with a storage device 2. An output to the lock line 5 of each processor 1 forms logical sum or logical product on the lock line 5. In accessing a series of specific[readout-correction- write]at the processor 1, three operations of[read lock],[data correction] and[write unlock]are continuously done in the processor 1. While one processor 1 performs a series of specific[readout-correction-write], the other processor 1 can perform normal leadout and write. |
