Abstract: The performance of an AGC loop typically depends on several factors, including gain linearity of the VGA and variation in the VGA bandwidth over the range of available gain settings. Although a resistively degenerated VGA provides for excellent gain linearity and immunity to process variations, the conventional architecture for a resistively degenerated VGA suffers from bandwidth variation over the range of available gain settings. Embodiments are provided herein of a constant-bandwidth VGA that utilizes resistive degeneration. To maintain a constant bandwidth over the range of available gain settings, degeneration resistors are coupled in parallel with compensation capacitors. In an embodiment, a compensation capacitor is determined to have a capacitance substantially equal to the decrease in total degeneration resistance that occurs as a result of an associated degeneration resistor being placed in parallel with the total degeneration resistance.

In one embodiment, the plurality of ingress recursion engines may be configured to recursively process the header portion, from outer-most header to inner-most header, until an adjacency value for the packet is determined. In some embodiments, each ingress recursion engine may be configured to process a header from the header portion.

Abstract: A system and method for the multi-stage analysis of incoming packets. Three stages are used, each of which addresses a particular category of threat by examining the headers and/or payload of each packet (“deep packet inspection”). The first stage detects incoming viruses or worms. The second stage detects malicious applications. The third stage detects attempts at intrusion. These three stages operate in sequence, but in alternative embodiments of the invention, they may be applied in a different order. These three stages are followed by a fourth stage that acts as a verification stage. If any of the first three stages detects a possible attack, then the packet or packets that have been flagged are routed to a central verification facility. In an embodiment of the invention, the verification facility is a server, coupled with a database.

Abstract: A system and method for preferred service flow of high priority messages between electronic devices is provided. The preferred service flow system includes preferred service flow queues, standard service flow queues, request/grant state machines and a controller. The method includes determining whether the standard processing rate of messages is acceptable, creating a preferred service flow queue and processing a high priority message through the preferred service flow queue. A preferred service flow queue will be created and the message processed using that queue when the standard processing rate is unacceptable and resources are available for the preferred service flow queue. If the standard processing rate is acceptable or resources are unavailable, a preferred service flow queue will not be created and the high priority message will be processed using the standard procedure for processing a message.
