    Abstract: A technique is provided for breaking a stalled condition or livelock in a processor having a replay queue. A livelock or stalled condition is detected. One or more instructions are temporarily stored in a replay queue. A release or break in the livelock or stalled condition is detected, and the instructions are then unloaded from the replay queue for replay or re-execution. For a multi-threaded processor, a stall is detected in one of the threads. Instructions of the stalled thread are temporarily stored in a replay queue, except the oldest instruction of the stalled thread which is allowed to replay or re-execute. This allows other threads to have access to execution and replay resources. Eventually, the oldest instruction will execute and retire, which breaks or releases the stalled thread. The instructions stored in the replay queue are then unloaded from the replay queue.

    Abstract: A method and system for controlling a heating device mounted on e.g. a satellite receiver antenna is disclosed. The method includes the steps of determining whether the signal strength is degrading, determining whether a temperature is below a threshold temperature, and operating a heating device on the antenna only if the signal is degrading and the temperature is below the threshold. The system includes a temperature sensor that samples a relevant temperature, a device that measures a signal strength of a signal received by the antenna, logic in communication with the temperature sensor and the measuring device for determining whether both the signal strength is degrading and the sample temperature is below a threshold temperature, and a control or switch device for operating a corrective device, such as a heater. The system and method herein automatically turns on an antenna heating device or other device to melt snow or frost accumulated on the receiver antenna upon detecting a loss of signal strength and a sufficiently low temperature.

    Abstract: An encoding and decoding system that includes a model implemented hardware or software that is capable of operating on arbitrary data (e.g., data of a different or variety of types.) The model generates a context and binary decision for each symbol, which a binary entropy coder that uses to generate a compressed bit stream. One context model is operable with arbitrary data and uses context bins of various orders to generate a context and a decision for each symbol in an input symbol stream. An entropy coder estimates probability and generates compressed data stream in response to contexts and decisions from the model and according to generated probability estimates.

    Abstract: Transforms such as the DCT are useful for image compression. One close relative of the DCT is preferred for its arithmetic simplicity. A method and apparatus is described whereby the quantization operates with speeds comparable to 16 bit transforms yet the mean squared error is comparable to that of a 32 bit transform. The factorability of the transform into a relatively rapid set of additions and a set of multiplications permits an efficient pipelined data flow wherein the addition sections of the vertical and horizontal transforms are performed by the same hardware prior to a final multiplication.
