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 ...

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 ...

This product training module introduces Renesas’ RX Direct Memory Access Controller. The presentation discusses the different DMAC transfer modes and the registers that control the function of the ...

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 ...

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 ...

Here’s the thing about coding. When you’re working on embedded projects, it’s quite easy to run into hardware limitations, and quite suddenly, too. You find yourself desperately trying to find a way ...

Secured-core PCs help mitigate attacks like Thunderspy by requiring a device to be unlocked to gain direct memory access. When you purchase through links on our site, we may earn an affiliate ...

A Dutch researcher has detailed nine attack scenarios that work against all computers with Thunderbolt shipped since 2011 and which allow an attacker with physical access to quickly steal data from ...
