URGENT: Peripheral to Memory DMA Transaction

Hello, may I know how to transfer data from peripheral to memory using DMA? It is quite confusing from memory-to-memory transfer. please help! thanks!

Thanks! So, for the time being, I just stick to my setting: data is 32bit, deep of FIFO 131072 words (will it be too big?), exclude 'full, empty and usedw' signal but enable circuit protection.

besides, how to connect the full/empty signal to interrupt line? can it be done in VHDL code only? eg: like full = 1, then de-assert the chipselect of the peripheral.

thanks!
