2 megahertz, but this presents a timing problem very comparable to the one in the example.
Because of the narrow or impossible timing constrains, DMA as described above is not recommended for direct scanning of regular memory for video display, but is the preferred method for making quick transfers of information. For example, DMA is often used when a picture or part of a picture needs to be moved quickly between a frame buffer and regular memory, or when the contents of buffers for a floppy disk need to be quickly transferred to new locations.
In general a DMA controller is used as follows..................[:=> Show Contents <=:]

input/output devices as shown in fig. Assume one of the I/O devices is a disk drive and that the computer must load a program from this drive into memory.

The CPU would read the first byte of the program and then write that byte to memory. Then it would do the same for the second byte, until it had loaded the entire program into memory.

implementing dma in a computer system

A DMA controller implements direct memory access in a computer system.

It connects directly to the I/O device at one end and to the system buses at the other end. It also interacts with the CPU, both v..................[:=> Show Contents <=:]

from memory. This would be a complete waste of time for the processing power of the CPU.
For the computer to be efficient, it needs special circuitry to read these bytes. One solution is to store these bytes in a special display memory with built-in scanning circuitry and an arbitration scheme between the memory accesses by the scanning circuitry and memory accesses by the CPU. (This solution is mostly used today by the use of Video RAM – VRAM.) This is sometimes called a frame buffer. The memory in such a system is said to be dual ported because there are two different ways to access it.

eo controller). The other modes operates in a similar fashion. For a burst mode transfer:-

1) The processor loads the DMA controller with the start address of the destination in memory and the number of words to transfer.

2) When the device delivering or requesting data is ready, the DMA controller is signaled. In turn, the
controller signals the processor that a DMA transfer is pending.

3) The processor acknowledges the request, finishes its current instruction, and then floats the address, control, and data buses.

4) The DMA controller now provides address and control signals to..................[:=> Show Contents <=:]
