System authorizing direct data transfers between memories of several components of that system

A computer system, comprising:

• a plurality of components, wherein one or more of the components comprises a peripheral device;
• and
• at least one switch connected to each peripheral device, wherein the switch is configured to transfer a command to the components,
• wherein a first peripheral device is configured to initiate at least one command for direct access to at least one of a plurality of memory areas, each of the memory areas being associated with a distinct component of the plurality of components,
• wherein the switch is configured to send at least a part of the at least one command to one or more of the components,
• wherein at least one of the components includes a second peripheral device, wherein the second peripheral device comprises:
• a local memory,
• a memory controller, and
• a processing unit configured to receive the at least one command, wherein the command is for direct access to the local memory, wherein the command is received from the first peripheral device via the switch, and wherein the processing unit is also configured to send the received command to the memory controller,
• wherein the second peripheral device is configured to send data to or receive data from the first peripheral device according to the command, and wherein the first peripheral device is configured to perform a direct transfer of data to or from each of the components with a single command.

A computer system comprising a plurality of peripheral devices and at least one switch connected to each device of said plurality of peripheral devices, said switch comprising means for transferring a command to a plurality of components of said computer system, the computer system comprising:

• a first peripheral device of the plurality of peripheral devices, comprising means for initiating at least one command for direct access to a plurality of memory areas, each of said memory areas being associated with a distinct component of said plurality of components,
• wherein said switch comprises means for sending at least a part of said at least one command to each component of said plurality of components,
• wherein at least one component of said plurality of components comprises a second peripheral device of the plurality of peripheral devices, said second peripheral device comprising:
• means for receiving at least one command for direct access to an area of a memory of said second peripheral device, said command being received from said at least a first peripheral device via said switch, and
• means for sending said at least one received direct access command to a component of said second peripheral device,
• said system enabling said first peripheral device to perform a direct transfer of at least one item of data to or from a memory of said first peripheral device from or to each component of said plurality of components on the basis of a single command.
