How to use Direct Memory Access (DMA)Kenton Williston
I'm writing a Linux kernel driver that must transfer up to 512KB of data from an FPGA (connected via the i.mx53's EIM) to a memory buffer. I have it working with memcpy() right now, but need to use DMA to offload the copying from the CPU. The FPGA has be...
Hi: I have too many uart data to receive, and the frame length is not sure, and I do not want so many uart interrupt, so I want use DMA, but the dam
Shows how to use the Windows 95/98 operating system's Direct Memory Access (DMA) or the faster Ultra DMA (UDMA) check box to speed up the hard disk drives. Process of finding out whether the system is capable of hard disk DMA/UDMA; Make an emergency boot diskette and verify that it ...
the security controls it provides—now you have complete and unfettered access to the hardware. This renders device control implemented by the OS completely ineffective. I am unaware of any hacking tools that currently use this technique, but I very much doubt that this has not already been ...

If you use a value greater than 1 for -SubscriptionStreams parameter of the Distribution Agent, you must ensure that updates to primary key columns are successful. For example: Copy update ... set pk = 2 where pk = 1 -- update 1 update ... set pk = 3 where pk = 2 -- update ...

I tried implementing AXI DMA as explained here: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/1027702787/Linux+DMA+From+User+Space+2.0 I did the same as the prototype (the 1st one) but without the use of system coherency and using the Xilinx 2021...
The same concept applies to downtrends. The DMA is adjusted to align with the pullback highs during the downtrend. On future pullbacks, the trader can watch to see if the DMA still provides resistance. If it does, that may provide a short trade opportunity. Displaced Moving Average (DMA) ...
