Thanks to microcontrollers that aren’t trapped in the 1980s, new techniques can be used to drive these LED matrices. Most of the more powerful ARM microcontrollers come with DMA, a peripheral ...

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

The other difference from most conventional microcontroller architectures is the dual-port DMA memory, which is primarily intended for use by the DMA controller.

Traditionally, higher-end, 32-bit microcontrollers featured co-processors and DMA controllers. Fewer 8- and 16-bit devices included these more complex adjuncts.

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 ...

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.

STMicroelectronics has put plenty of analogue features and DMA (direct memory access) into its latest 8bit 8pin microcontroller. Dubbed STM8L050, alongside two comparators, it has four-channel 12bit ...

Peripheral DMA Controller Relieves CPU of Peripheral-to-Memory Transfers -- Conventional ARM9-based processors use load/store instructions that require at least 80 CPU cycles to transfer a single ...
