Title: Intra-macroblock video processing
Inventor: MOSS BARRY
IPC: H04N7/34
Filed: 2008-03-27
Abstract: A system for processing sub-blocks of a macroblock of a video frame. In an example embodiment, the system includes a first module that is adapted to process each sub-block of the macroblock, wherein each sub-block is associated with a predetermined position in a first sequence. The processing of certain sub-blocks in the first sequence requires results of processing of one or more previously processed sub-blocks in the first sequence. A controller selectively enables the first module to process each sub-block of a second sequence that is altered from the first sequence so that the first module implements parallel or pipelined processing of certain sub-blocks of the macroblock. In a more specific embodiment each sub-block in the first sequence of sub-blocks is consecutively numbered 0-15 according to H.264 standards.

Patent CA-2699562-A1 (CA)
Inventor: PETERSON DAVID A
IPC: G06F15/16
Filed: 2008-09-19
Abstract: The present invention is directed to computer systems, methods and/or hardware where one or more guest operating systems exchange instructions with the processing hardware (see DEFINITIONS  section) through a controller kernel. Even though the instructions are exchanged through the controller kernel, rather than directly between the OS and the processing hardware, the controller kernel does not change the instructions out of native form. The controller kernel refrains from virtualizing or emulating the instructions. For this reason, the controller kernel cannot be considered to be and/or include middleware, a hypervisor or VMM.  The use of the controller kernel can be helpful in computer systems with multiple guest OS's because it allows multiple containerized OS's to simultaneously run on a single set of processing hardware. For example, the multiple containerized OS's can be used to run multiple terminals. The use of the controller kernel may also be useful even if there is a single guest operating system. For example, a LINUX controller kernel has been found to speed up the operation of the Windows Vista operating system running as the guest OS, relative to the speed of Windows Vista running directly on the same processing hardware in the conventional way.
