Title: Dma controller
Inventor: YONEZU KAZUYA
IPC: G06F13/28
Filed: 1990-04-26
Abstract: PURPOSE:To reduce the load of a CPU and to improve the DMA (direct memory access) transfer efficiency by performing continuously the DMA transfer operations in the frequency set by the CPU. CONSTITUTION:A CPU 1 sets the proper DMA transfer frequency to a register 12 of a DMA controller 2 via a data bus 5 before the DMA transfer. Thus the prescribed signals are outputted from a counter 13 in each set DMA transfer frequency so that the DMA transfer is interrupted. Therefore the DMA transfer is continuously carried out by the set frequency and the DMA transfer is not frequently interrupted compared with a single mode. Thus the DMA transfer operations can be continuously carried out without affecting the processing of the CPU 1. As a result, the load of the CPU 1 is reduced and at the same time the DMA transfer efficiency is improved.
