This video lecture is about the Direct Memory Access (DMA). Data transfer to and from peripherals may be handled in one of three possible modes:
1)Programmed I/O
2)
Interrupt-initiated I/O
3)
Direct Memory Access (DMA)
This video explains explains:
What is DMA?
What is DMA Controller (DMAC)?
How DMA Works?
How to make CPU idle in DMA?
Types of DMA Transfers using DMA Controller?
Explains Burst Transfer and Cycle Stealing method of DMA Transfer?
There are three different modes of DMA data transfer which are:
1) Burst Mode
2) Cycle Stealing Mode
3)
Interleaving Mode
