The
performance of a 2MHz CPU is calculated as 2 MIPS. Data Transmission speed of a
scanner is calculated as 9600 bytes per second. Direct Memory Access (DMA)
controller transfers 16-bit data from scanner to memory in one clock cycle
using cycle stealing. If such a controller is attached with a system, then
calculate the percentage of speed dropped by using DMA controller.
