Abstract

PURPOSE:To contrive the improvement of the processing efficiency by executing in parallel a DMA transfer to a track buffer from a magnetic disk device, and a DMA transfer to a host device from the track buffer. CONSTITUTION:By providing a 2-channel DMA controller 23, and using the first channel of a high priority, the first DMA transfer to a track buffer 11 from a magnetic disk device 3 is executed, and also, by using the second channel of the 2-channel DMA controller 23, the second DMA transfer to a host device 2 from the track buffer 11 is executed, and the first and the second DMA transfers are executed in parallel. In such a way, the data processing can be executed at high speed.
