Abstract: A circuit generates a global clock signal with a pulse width modification to synchronize processors in a parallel computing system. The circuit may include a hardware module and a clock splitter. The hardware module may generate a clock signal and performs a pulse width modification on the clock signal. The pulse width modification changes a pulse width within a clock period in the clock signal. The clock splitter may distribute the pulse width modified clock signal to a plurality of processors in the parallel computing system.

Abstract: A system and method for allowing users to view secure data while excluding others from viewing. The method includes generating a stream of first data frames including secure data content to be viewed on a display device; inserting second data frames within the stream in a manner to thereby render a displayed image of the secure data unreadable on the display device. Shutter glasses, to be worn by an authorized user, are provided to receive signals from the computer device and, in response to received signals, filter out the second data frames thus enabling the viewer to view the secure data to the exclusion of nearby observers. The second frames are generated and interspersed within the first video frames having secure data by software executing on a conventional computing device. The second frames may include random text interspersed according to a regular or irregular pattern, or may include color and intensities to exploit deficiencies of human visual perception.
