A '''peripheral DMA controller''' ('''PDA''') is a feature found in modern [[microcontroller]]s. This is typically a [[FIFO (computing and electronics)|FIFO]] with automated control features for driving implicitly included modules in a microcontroller such as [[UART]]s.

This takes a large burden from the [[operating system]] and reduces the number of [[interrupt]]s required to service and control these type of functions.
