Direct memory access (DMA) is a means of having a peripheral device control a processor’s memory bus directly. DMA permits the peripheral, such as a UART, to transfer data directly to or from memory ...
Part 1 shows how to build a software framework, choose between cache and DMA, and partition instructions and data for optimal performance. Part 3 explains how to optimize code placement and data ...
High-end microcontrollers often use large, complex crossbar switches and other technologies to maximize throughput and performance. Low-end microcontrollers typically feature a simple bus structure.
