hi to all!
i have a doubt if anyone can help me out in solving this problem.
there is "hidden DMA transfer" mode in which the DMA will keep
monitoring processor and whenever processor is free for few cycles,DMA
will take the control of the data bus for that few cycles. but this
mode isnot accessible everywhere . so my doubt is whether P4 processor
allows such mode of transfer or not .and if at all it allows such mode
of transfer ,how it can be accomplished using C language i.e.how DMA
can be accessed using this language.
thanx!
.
