摘要

The circuit is for digital data communications with direct memory access or DMA in a digital information communications system with an input/output or I/O processor. The process involves identifying a starting command word via the I/O processor (20) and initialising and activating a DMA controller (24) according to the identified start word. The I/O processor receives an interrupt generated by the I/O controller and finally performs an error check routine depending on the interrupt received. USE/ADVANTAGE - Esp. for effective, efficient and reliable digital data communications between the elements of an avionic system using a new and improved type of DMA controller.
