Abstract

PURPOSE:To obtain processing time margin of CPU, by DMA of m-sample at a bundle in the storage of m-sample's share to the first-in/first-out (FIFO) register. CONSTITUTION:Data 1-n every sampling period DELTAt from an A/D converter 4 are stored in an FIFO register 6, this processing is made continuously in m-times, and data for m-sample is stored in the FIFO register 6, where (m) is suitably determined with the sampling speed and the processing speed at CPU side. After the data for m sample's share is stored in the FIFO register 6, the said m-sample data are in DMA operation in the memory 7 with the control 5. Thus, DMA can be made once in m+DELTAt, allowing to obtain sufficient processing time margin for CPU.
