Peripheral DMA controller
Encyclopedia
A peripheral DMA controller is a feature found in modern microcontroller
s. 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 interrupt
s required to service and control these type of functions.
Microcontroller
A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM...
