摘要
A heterogeneous processing element model is provided where I/O devices look and act like processors. In order to be treated like a processor, an I/O processing element, or other special purpose processing element, must follow some rules and have some characteristics of a processor, such as address translation, security, interrupt handling, and exception processing, for example. The heterogeneous processing element model abstracts an I/O device such that communication intended for the I/O device may be packetized and sent over a network. Thus, a virtualization platform may packetize communication intended for a remotely located I/O device and transmit the packetized communication over a distance, rather than having to make a call to a library, call a device driver, pin memory, and so forth.
