Abstract:
A method and system for accessing a computer system memory without processor intervention is disclosed. In one embodiment, the method includes initiating a predetermined communication protocol between a first device and a second device, the first device including a first processor, a first memory and a first communication interface, the second device including a second processor, a second memory and a second communication interface. The predetermined communication protocol enables an access operation to be performed on the first or second memory without intervention by the first or second processor. In one embodiment, the predetermined communication protocol utilizes a plurality of predefined packet types which are identified by a packet header decoder.
