Self Doubt
Since a DMA contoller is connected with the number of I/O devices. Is it possible that DMA controller (say master) is connected with number of other DMA controllers (say slaves). And with these slaves DMA controller, a number of I/O devices are connected?

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??
