摘要： Embodiments of an I/O module, processing platform, and method for extending a memory interface are generally described herein. In some embodiments, the I/O module may be configured to operate in a memory module socket, such as a DIMM socket, to provide increased I/O functionality in a host system. Some system management bus address lines and some unused system clock signal lines may be reconfigured as serial data lines for serial data communications between the I/O module and a PCIe switch of the host system.

摘要： A system for screening data packets transmitted between a network to be protected, such as a private network, and another network, such as a public network. The system includes a dedicated computer with multiple (specifically, three) types of network ports: one connected to each of the private and public networks, and one connected to a proxy network that contains a predetermined number of the hosts and services, some of which may mirror a subset of those found on the private network. The proxy network is isolated from the private network, so it cannot be used as a jumping off point for intruders. Packets received at the screen (either into or out of a host in the private network) are filtered based upon their contents, state information and other criteria, including their source and destination, and actions are taken by the screen depending upon the determination of the filtering phase. The packets may be allowed through, with or without alteration of their data, IP (internet protocol) address, etc., or they may be dropped, with or without an error message generated to the sender of the packet. Packets may be sent with or without alteration to a host on the proxy network that performs some or all of the functions of the intended destination host as specified by a given packet. The passing through of packets without the addition of any network address pertaining to the screening system allows the screening system to function without being identifiable by such an address, and therefore it is more difficult to target as an IP entity, e.g. by intruders.

摘要： A virtual I/O processor (VIOP) is implemented using a programmed I/O (PIO) unit. The PIO unit is complemented by a VIOP interrupt, a VIOP interrupt handler, and a number of VIOP data structures. Preferably, the PIO unit is further complemented with a set of dedicated I/O global registers, a number of VIOP library read/write routines for various I/O device types, and non-blocking read and write operations. During execution, these elements cooperate with each other to perform multiple sequences of programmed I/Os as if they were being performed by a dedicated I/O processor.
