US 7,010,579 B1 · Direct data routing system

Abstract

A system of data transfer between a first processing device and a second processing device which speeds data transfer by eliminating intermediate storage steps. A plurality of memory storage devices are provided between the first and second processing devices for the purpose of synchronization and alignment. One of the memory storage devices is associated with the second processing device. In accordance with a first embodiment of the present invention, a new instruction is provided to implement a data transfer function for transferring data directly between a first memory storage device and a second memory storage device, without intermediate storage in a processor register. Thereafter, the data is transferred from the second memory storage device to the memory storage device associated with the second processing device. In accordance with a second embodiment of the present invention, data is efficiently transferred directly between a first memory storage device and the memory storage device associated with the second processing device, without intermediate storage in either a processor register or a second memory storage device.

Dependent claims

A data transfer method for transferring data between two processing systems, comprising:

receiving a wireless signal data packet from a radio frequency physical layer processing system;
storing the received data packet into a first memory device associated with the media access control layer, the received data packet comprising a header portion and a data portion;
processing the header portion of the packet by a media access control layer processing system while the data packet is stored in the first Memory device;
determining whether the data packet is one of group consisting of a video stream and an audio stream by the media access control layer processing system;
transferring the header portion to a main memory and the data portion to a memory associated with a host processing system responsive to determining the data packet is one of the group consisting of a video stream and an audio stream;
and
executing a single processor instruction on the media access control layer to transfer the header portion and the data portion to the main memory responsive to determining the data packet is not one of group consisting of a video stream and an audio stream;
wherein said media access control layer processing system and the host processing system operate independently.
