In the most simple computer system architecture, all control lies with the CPU (Central Processing Unit). This means not only the execution of commands that affect the CPU’s internal register or cache ...

Transferring large blocks of data within memory as well as to and from peripherals. Direct memory access (DMA) avoids loading the CPU's register with small amounts of data from memory and storing them ...

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 ...

Last time, in Part 1, we introduced somebasics behind Direct Memory Access (DMA) -why it's needed, and how it's structured and controlled. This time,we'll focus on the classifications of DMA transfers ...

Apple's Unified Memory Architecture first brought changes to the Mac with Apple Silicon M1 chips. There are clear architectural benefits for the hardware — and it is both good and bad for consumers.
