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 application note presents the Direct Memory Access (DMA) control, its basic set-up and operations. The document includes the usage examples of the DMA controller and the DMA Trigger Factor ...

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 ...

Now that there are embedded media processors available that can handle both MCU and DSP tasks, C programmers who are very familiar with the MCU model of application development are transitioning into ...

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 ...

The manufacturers have issued BIOS updates to address the issues, but researchers warn DMA attacks are likely possible against a range of laptops and desktops. Vulnerabilities in Dell and HP laptops ...
