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 ...

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 ...

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 ...

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 ...

Direct memory access (DMA) systems in computers are more powerful than you might think, and [Bruce Land] and [Joseph Primmer] have done some clever hacking to take full advantage of this on the PIC32 ...

Multicast, a technique commonly used in networking systems, allows a given processing unit to send a single data stream to multiple destinations at the same time efficiently. Typically, the switch ...

A new technical paper titled “Rethinking Programmed I/O for Fast Devices, Cheap Cores, and Coherent Interconnects” was published by researchers at ETH Zurich. “Conventional wisdom holds that an ...

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 ...

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 ...
