Peripheral DMA controller

A peripheral DMA controller (PDC) is a feature found in modern microcontrollers. This is typically a FIFO with automated control features for driving implicitly included modules in a microcontroller such as UARTs.

This takes a large burden from the operating system and reduces the number of interrupts required to service and control these types of functions.
