DMA Doubt
can someone explain what is preparation time in DMA exactly? and why is it multiplied by CPU cycle time in most of the questions here? does preparation time means that a word is brought into disk controller buffer from hard disk and it utilizes CPU? PS-DMA is giving me headaches!!!

DMA Self Doubt
A device has been used in DMA. A word of 4 bytes can be transferred when it is available. The memory cycle time is 40 ms and CPU is idle for 10% of its time. What is the data transfer rate of the device for Burst mode and Cycle stealing mode. I'm getting Burst mode - 11.11 B/s Cycle stealing - 10 B/s Is it correct??
