Abstract: A system for enhanced resource utilization includes a network interface with access to memory of a device, in communication with an operating system of the device. The system receives, from the operating system, an identification of a predetermined amount of the memory for a packet buffer, store multiple packets in the allocated memory. A total size of the multiple packets is smaller than or equal to the predetermined amount of memory. The system generates a status record for each received packet stored in the allocated memory, and stores the generated status records in the allocated memory. The system also allocates a socket buffer for each packet stored in the allocated memory such that the socket buffer has reference to the corresponding packet in the allocated memory.

Abstract: A QAM data signal timing recovery loop feedback element provides a fixed sampling time offset adjustment to two continuously variable digital rate interpolators/decimators to produce a quadrature output stream at a programmed rational rate multiple of the actual baud rate of the received data signal. The continuously variable digital rate interpolators/decimators are configured at startup so as to produce output streams at the same programmed rational rate multiple of the nominal baud rate of the anticipated received data signal, assuming the fs sample timing offset adjustment stream provided by the timing recovery feedback element to be identically 0. The “nominal” fixed sampling rate fs of the received analog input signal need not be rationally related to the nominal baud rate of the anticipated received data signal.

Abstract: A digital automatic gain control circuit for a receiver includes an averaging block and an adjustment block. The averaging block receives a length of a digital sample stream that represents an incoming analog signal and produces an absolute average signal. The adjustment block receives the absolute average signal and a reference signal and outputs an adjustment signal for controlling gain. The adjustment signal is based on a difference between the absolute average signal and the reference signal. In an alternative embodiment, a method of controlling gain according to the invention includes the steps of calculating an absolute average of an incoming signal, and comparing the absolute average to a reference to produce an adjustment signal based on a difference between the absolute average and the reference.
