1 1 vote A DMA module is transferring characters to memory using cycle stealing, from a device transmitting at 12800 bits per second.The processor is fetching instructions at the rate of 2MIPS. By how much the processor be slowed down due to DMA activity?

Is it your default assumption or it is fact? 0 0 replyShare soumayan bandhu commented Jan 20, 2018 reply Follow flag Is CPU slowdown=time to complete 1instruction/1byte transfer time ? 0 0 replyShare utk0203 commented Jan 20, 2018 reply Follow flag https://gateoverflow.in/62528/cycle-stealing-dma for ref. 0 0 replyShare Ajay Jadhav commented Jan 20, 2018 reply Follow flag read the word 'character' in question. 0 0 replyShare Please log in or register to add a comment.
