6) A DMA controller transfers 32 bit words to memory using cycle stealing. The words are assembled from a device that transmits characters at a rate of 2400 characters per second. Each character is 8 bit length. The CPU is fetching and executing instructions at an average rate of 1 million instructions per second. By how much will the CPU be slowed down because of the DMA transfer?
