摘要： A digital differential analyzer (DDA) is connected through a direct memory access bus (DMA bus) to a host processor so as to receive an operation defining parameter and data, thereby to process a differential analysis as a digital operation.The DDA has mainly an arithmetic processor for DDA operation, and a control processor for performing the control concerning DMA to the host processor and the start and end control of the DDA operation which is performed by the arithmetic processor. This DDA decreases the amount of program to be processed by the host processor.
