Techniques are described to multiply two numbers, A and B. In general, multiplication is performed by using Karatsuba multiplication on the segments of A and B and adjusting the Karatsuba multiplication based on the values of the most significant bits of A and B.

A method of processing data includes writing a data block of size m where m is greater than zero into a queue. The method also includes reading a data block of size n where n is greater than zero from the queue and where the size of n is different from the size of m. The queue can be a FIFO queue. The queue can also have a configurable size.
摘要:
An apparatus and method for managing a frequency of a computer processor. The apparatus includes a power control unit (PCU) to manage power in a computer processor. ThePCU includes a data collection module to obtain transaction rate data from a plurality of communication ports in the computer processor and a frequency control logic module coupled to the data collection module, the frequency control logic to calculate a minimum processor interconnect frequency for the plurality of communication ports to handle traffic without significant added latency and to override the processor interconnect frequency to meet the calculated minimum processor interconnect frequency.

A method and apparatus for providing a flexible and scalable videoconferencing system for use in connection with a network provides for scalably encoding an image sequence for transmission onto the network. The encoding enables the encoded image sequence to be decoded at any one of at least two spatial resolutions and any one of at least two frame rates. The decoder, depending upon the computing platform, its resources, speed, and efficiencies, can select to decode the received image at any of the available spatial resolutions and at any of the available frame rates. A lower spatial resolution and/or a lower frame rate require less computing resources. Multiple received image sequences can be decoded simultaneously, at, for example, a lowest resolution. The decoded images can be displayed for viewing on the computer monitor at the desired spatial resolution level and frame rate.
