Why does DMA have priority over the CPU when both request a memory transfer?
The data transfer monitored by DMA controller which is called as DMA channel. The CPU is included only at the starting and end of the transfer, when the CPU wishes to read or write a block of data, it issues a command to DMA Channel by sending read/write operation, address of I/O, number of words to be read or written, as DMA have priority over the CPU when both request a memory transfer.
Data Transfer Two most fundamental data transfer instructions in 8086 microprocessor are XCHG and MOV. Let's give illustrations of the use of these instructions. Program 1:
