While DMA to and from the SPE is adequate for moving blocks of data, there's often a need for the ability to send smaller messages faster.

The DMA engine passes data directly from the kernel buffer to the protocol engine, thus eliminating the remaining final CPU copy.

These all need to be quadword aligned, so that you can copy it into your main program and use the values with DMA transfers.

Whether it's an argument passed in or an address gotten some other way, the DMA targets must be aligned on cache lines (16 bytes).

The results demonstrated that PECH-DMA could greatly enhance the removal efficiency of NTU and organic substances.

This will be important as you learn how to use the memory flow controller's DMA facilities.

An MFC can have multiple concurrent DMA requests to one address space outstanding from both the PPE and the SPU.

In the article, we introduce each module of DMA controller custom logic including the interface and the state machine.

Once a data access request is detected, a VDD driver may issue a DMA data request to perform the data access request from the VDD.

This command causes the SPE to immediately return with the status of the DMA channels.

I slowly debugged the DMA unit the same way as the T65, sometimes adjusting clock timing if data values were not being read properly.

The DMA command can take a range of values (see Resources for information on where to find the ones not listed here).

The structure and dynamic mechanical properties are investigated via SEM, DMA, etc.

The results showed that using DMA determined the bonding effect of temperature for curing reaction.

In some cases, the data passed in as arguments will have more addresses that are, in turn, DMA-ed over in whole or in part.

Step three: the third copy happens as the DMA engine passes the data from the kernel socket buffers to the protocol engine.

The DMA controller can generate a CPU interrupt for each of the six channels.

The SPU queues a DMA GET to pull a portion of the problem data set from main memory to a buffer.

The DMA transport is the preferred transport for the Device Emulator.

All of the data transfers will use the MFC's DMA facilities, controlled through SPE channels.

The SPE can't hold that much data at once in the 256KB local store, but it can DMA over one chunk at a time for processing.

The DMA controller supports two separate methods for handling legacy DMA via the PCI bus.

While DMA channels bypass the CPU, devices that use DMA are still configured with IRQ ports.

You then use a DMA command to fetch the full structure, and wait for the DMA to complete.

No suitable DMA Channels is available for the Sound Blaster Card .

Some DMA related issues with older CD-ROM drives are known to be resolved in this way.

Maybe you want DMA on your 16bit system. Who knows?

With synchronous transmissions (no DMA), the driver knows right away when the frame has been uploaded on the NIC.

If you are unsure as to whether your system can handle DMA transfers, please contact your hardware manufacturer to verify.

Using spu_mfcstat allows you to both check on the status of DMA requests and wait for them.

At last, the print picture of Spray-paint Graph Plotter is given in DMA mode in this paper.

Use the DMA transport that Visual Studio 2005 provides for connecting to the Device Emulator.

The SPU queues a DMA PUT to transmit the buffer back to main memory.

Next, it performs a DMA transfer to copy in the parameter structure from the PPE.

A fence establishes the constraint that a given DMA transfer only execute after all previous commands using the same tag have completed.

Change the selection from "DMA if available" to PIO only, and click OK.

The Cell BE Handbook defines the sequence of channel operations needed to perform a DMA transfer on pages 450-456 (see Resources).

Queue a DMA PUT to transfer the buffer back to main memory.

So how does this wait for the DMA operation to complete?

So that the entire DMA transfer address becomes available on the address bus.

Connecting to the Device Emulator using the DMA transport.

Secondly, a new structure of the one-directional dedicated DMA controller based on data stream is designed for the output of audio PCM data.

You can avoid this connection issue by using the DMA transport for the emulator.

The problem is that there are unusually strict alignment requirements on data that will be transferred through DMA.

Queue a DMA GETB to refill the buffer with more data after the existing data is stored back.

If there are no bufffers marked "filling, " wait for all DMA PUT operations to complete and exit.

Unless you have some serious specific reason to use the TCP Transport, use the DMA transport to avoid network issues.

Then repeat the steps above to change the selection to DMA if available.

The organization of DMA system is illustrated on Fin3-39.

I know I can never say enough praise of DMA.

This is because you are using barriers with your transfers, and you are using the same DMA tag for them.

I know I can never say enough praise of DMA.

This is because you are using barriers with your transfers, and you are using the same DMA tag for them.

There are eight standard DMA channels (0-7); DMA 4 is reserved and cannot be used by any device.

As soon as line buffer 1 is switched on, then the DMA will quickly refill line buffer 2.
