Answer please
Consider a system in which bus cycles takes 750 ns. Transfer of bus control in either direction, from the processor to I/0 device or vice versa, takes 300 ns. One of the I/0 devices has a data transfer rate of 32 KB/s and employs DMA. Data are transferred one byte at a time. For how long would the device tie up the bus (in ms) when transferring a block of 160 bytes in DMA burst mode?
