IPC: G06F12/06
Filed: 1989-10-05
Abstract: PURPOSE:To attain rapid access of a memory by setting up a division method for dividing a memory into plural banks and operation to be executed by an arithmetic means to optimum states matched with the generation characteristics of read requests. CONSTITUTION:When a read request is applied to a bank holding a forecasting address, a comparing means 103 for the bank concerned decides whether the read request address coincides with the forecasting address or not and informs the decided result to a control means 5. The control means 105 sets up a buffer means 104 to an active state to wait the information, and when the decision indicates coincidence, the means 105 immediately outputs a read completion signal 112. When the decision indicates discrepancy, the control means 105 outputs an operation inhibition signal 113 and a holding inhibition signal 114 so that an address inputted from the external can be directly applied to the memory bank and outputs the read completion signal 112 after the lapse of a memory access time. Thus, the rapid reading of the memory can be attained.
