Good video sir.can you tell me how to use DMA in Embedded C,means how to start program for DMA if my peripherals are like when switch pressed LED will glow I want this process will done through DMA???is it possible?? REPLY

is DMA provisioned an separate bus to data transfer or is it multiplexed over the general bus.

Question: Please correct me if I am wrong anywhere. When the bus mastery is held by DMA controller, the CPU essentially is continuing its work (instructions). During this process, should the CPU wait if it needs to read or write to CPU? (as the bus is being used by DMA device) If yes, doesn't this reduce the performance?

the cpu can always switch to a different cpu bound task and put this task thats waiting for i/o in i/o blocked queue, the cpu has always some work to do.

Sir, at 29:00, u explained that while DMA Data Transfer is happening, the CPU is in suspended animation. Say, can't the CPU do some other work, wherein we do some kind of processing on some other block of data, tht had been previously loaded from the Memory, whose is not having dependency on the presently Loaded data..Then i suppose, we can save a lot of Cycles, and can achieve a kind of Parallel Pipelined Processing...?

As your query is just a week old, I am responding. 1. CPU can carry on with any internal activity that does not need a bus access (as has been mentioned elsewhere in the lecture). 2. In that case, CPU's number crunching and DMA's data transfer to Memory is going on in parallel.

Sir, Thanks a lot for the reply...Then as per the 1st point, any embedded code which will be accessing Peripherals via DMA must use the BUS Address and not the Physical Address of the Peripheral, say if the GPIO is having Physical address of 0x20nnnnnn, which is mapped to Bus address of 0x7Ennnnnn..Then we should use the bus address as 0x7Ennnnnn and not the physical address to R/W Data to it...

Raman Subramanian Hello Sir , i have question ..suppose consider the scenarion , one thread is writing on LCD screen , while DMA process is happening in parallel...now in the middle while DMA is happening , one screen immediately need to display and that requires the access of data bus , in that case DMA will be put on hold or how ...????
