摘要
介绍使用DMA芯片8237A,设计了单片机系统下DMA工作方式的硬件及软件,实现了大量数据的快速传递与存储.实际使用证明,单片机系统下的DMA方式是可行的.
The hardware and software of DMA-mode for Single chip computer are designed by using 8237A DMA chip. Bulk Data have been transferred rapidly and stored. The operations show that the DMA mode for single chip computer is feasible.
