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 ...

And if that doesn't work, well, now you know why I suggested that you make a full backup. You can always restore your system (ideally, from DOS, to be sure the Registry gets completely overwritten) ...

This Application Note explores the implications associated with performing Direct Memory Access (DMA) operations on an ARM multi-core system such as the ARM11 MPCore and Cortex-A9 MPCore. The target ...

In theory, direct memory access (DMA) operations are simple to understand; a device transfers data directly to or from a memory buffer managed by the CPU. Almost all contemporary devices perform DMA, ...

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 ...

What is Remote Direct Memory Access (RDMA)? Remote Direct Memory Access is a technology that enables two networked computers to exchange data in main memory without relying on the processor, cache or ...
