    摘要： Embodiments disclosed include a mechanism in a system and method for significantly reducing power consumption by reducing computation and bandwidth. This mechanism is particularly applicable for modern 3D synthetic images which contain high pixel overdraw and dynamically generated intermediates images. Only blocks of computation which contribute to the final image are performed. This is accomplished by rendering in reverse order and by performing multiple visibility sort in a streaming fashion through the pipeline. Rendering of dynamically generated intermediate images is performed sparsely by projecting texture coordinates from a current image back into one or more dependent images in a recursive manner. The newly computed pixel values are then filtered and control is returned to the sampling shader of the current image. When only visible pixels are projected optimal computation is performed. Several implementations are presented with increasing efficiency. An acceleration structure, termed a Draw Buffer, simplifies the process of projecting backward and utilizes a hardware managed dynamic memory object. This mechanism reduces computation by 50%, with significant bandwidth and power savings.

    摘要： A method for profiling network traffic of a network is presented. The method includes obtaining a cohesive flow-set based on a (port number, transport protocol) pair, identifying a statistically representative training set from the flow-set, identifying a network application associated with the (port number, transport protocol) pair, determining a packet content based signature term of the network application based on the training set, generate a nondeterministic finite automaton (NFA) using the signature terms to represent regular expressions in the training set, matching a portion of a new flow to the NFA in real time and identify a server attached to the new flow as executing the network application, and generate an alert in response to the match for blocking the new flow prior to the server completing a task performed using the new flow.

    摘要： Method and system for generating and processing multiple independent input data streams based on a high priority OS message framework such as an OS provided framework for processing mouse-messages. Multiple input devices generate motion that is sensed by motion sensors located on one or more motion sources, quantify the sensed motion, and provide resulting input data to a computer via one or more communication ports. One or more software subroutines process the provided data, separating them into multiple independent input streams according to their sources, and sending the streams to listening applications. The subroutines are preferably integrated at a low level of the OS architecture, thereby enabling low-latency, fully-functional high priority processing of the input data.
