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

The 32-bit microcontroller is ideal for this scenario, for if the DMA controller is trying to move to memory data coming in the Ethernet receive channel, the result is bandwidth resource contention.

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 ...

Atmel provides the CAP7E ARM7-based microcontroller with direct FPGA interfaces. The interface on the CAP7E affords the FPGA direct access to the AHB and peripheral-DMA controller on the CAP7L. Atmel ...

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.
