Peripheral DMA controller
open-in-new
<p>A peripheral DMA controller (PDC) is a feature found in modern <a href="/facts/Microcontroller/MKrnAhnm">microcontrollers</a>. This is typically a <a href="/facts/FIFO_(computing_and_electronics)/RctvBNgE">FIFO</a> with automated control features for driving implicitly included modules in a microcontroller such as <a href="/facts/UART/xMntJcsI">UARTs</a>. </p><p>This takes a large burden from the <a href="/facts/Operating_system/8XTuvMh2">operating system</a> and reduces the number of <a href="/facts/Interrupt/Mm6C4rpc">interrupts</a> required to service and control these type of functions. </p>
