Controller for direct access to a memory for the direct transfer of data between memories of several peripheral devices, method and computer program enabling the implementation of such a controller
The subject of the invention is in particular the direct transfer of data between first and second peripherals connected via a communication bus. For this purpose, the first peripheral comprises a controller for direct access to a memory having means (425) for initiating at least one command for dir...

| description | The subject of the invention is in particular the direct transfer of data between first and second peripherals connected via a communication bus. For this purpose, the first peripheral comprises a controller for direct access to a memory having means (425) for initiating at least one command for direct access to a region of a memory external to said first peripheral and means (400) for receiving at least one command for direct access to a region of a memory of said first peripheral, said command being received from said at least one second peripheral, and means (415) for transmitting said at least one received direct access command to a component of said first peripheral. The controller thus allows a controller of direct access to a memory of said at least one second peripheral to carry out a direct transfer of at least one data item to or from a memory of said first peripheral from or to said second peripheral. |
