Thanks to the DMA controller inside the STM32, the microcontroller is capable of sending and receiving data through SPI at the same time.

Most of the more powerful ARM microcontrollers come with DMA, a peripheral for direct memory access. Instead of having the CPU do all the work, the DMA controller can simply shuffle around bits ...

The ElanSC300 also includes mobile-computing peripherals, such as PLL clock generators, PCMCIA-card support, LCD-graphics control, a memory controller, DMA and interrupt controllers, a real-time clock ...

Another system optimization: Add a DMA controller to the system that is used to copy packets to/from the MAC/PHY chip from/to memory without having to go through the microprocessor, as is done in the ...

What methods are preferred in different classes of microcontrollers? Traditionally, higher-end, 32-bit microcontrollers featured co-processors and DMA controllers.
