Title: Dma controller
Inventor: OKAMOTO HISANORI
IPC: G06F13/28
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a direct memory access(DMA) controller with which processing can be efficiently performed even without requiring any mass RAM even in the case of DMA processing to deal with a lot of data. SOLUTION: Plural areas selected out of empty areas inside the RAM are respectively set to an area control circuit 7 of a DMA controller 6 as areas A and B by a CPU 1. First, the DMA controller 6 performs processing by utilizing the area A and at the time point when that processing is finished, the CPU 1 is interrupted so that processing can be continued by utilizing the area B. On the other hand, even when the DMA of the area B is finished by interruption processing, the CPU 1 judges whether data to be further processed exist or not and when such data exist, the area A is reset. Afterwards, until the requested processing is finished, DMA processing is continuously performed similarly by alternately utilizing the areas A and B.
