Direct memory acess
Consider a system in which bus cycle takes 500 ns. Transfer of bus control in either direction, from processor to device or vice-versa, takes 250 ns.One of the IO device has data transfer rate of 75 KB/sec and employs DMA. Data are transfer red one ... block of 256 bytes? b) calculate the same for cycle stealing mode Please explain in which mode we use bus cycle time and why?
