Abstract

PURPOSE:To reduce queuing by combining parallel access with block access. CONSTITUTION:The capacity of a data buffer BF is selected corresponding to the amount of data during block access. Access to a central processor CPU via a data buffer BF makes block access function in parallel. Therefore, the efficiency of bus utilization is improved to reduce queuing due to the memory in busy.
