WebJul 7, 2024 · Cycle stealing is a technique for memory sharing whereby a memory may serve two autonomous masters and in effect provide service to each simultaneously. One of the masters is commonly the central processing unit (CPU-q.v.), and the other is usually an I/O channel or device controller. WebGiven Solution : 1.) For Cycle Stealing Mode 1 word = 64 bits = 8 bytes is transferred in one cycle. Since total 64 bytes is to be transferred So total number of cycles = 64 / 8 = 8, 1 cycle time = 2µs , So time for 8 cycles is = 16µs Now time taken by disc to transfer 64 B is µ ( 64) / 10 6 = 64 µ s
