A Network Interface Controller (NIC) is a device typically connected to a PCIe bus that enables access to a network. It provides high bandwidth and can perform direct memory access (DMA) to read or write data directly to memory without involving the main processor. ...
This is termed direct memory access (DMA). To carry this out, a DMA controller is connected to the bus. This controller supplies the memory address locations where the data is to be put and so enables the data to be routed direct to memory. 3.3.1 Lab VIEW The software for use with ...
GDS enables a direct data path for direct memory access (DMA) transfers between GPU memory and storage, which avoids a bounce buffer through the CPU. This direct path increases system bandwidth and decreases the latency and utilization load on the CPU. The purpose of this guide is to help ...
