A method and apparatus for hardware-based anamorphic video scaling. In one embodiment, the method includes the fetch of zero or more new input pixels according to an entry of an input control memory corresponding to a current output pixel. Once fetched, the zero or more new input pixels replace at least one stored input pixel of N, input pixels. Using the updated N, input pixels and an N, coefficient set selected according to an entry of a coefficient memory corresponding to the current output pixel, a pixel computation, such as, for example, an anamorphic scaling computation, is performed. In one embodiment, the anamorphic scaling is performed by subdividing an X&#xd7;Y pixel frame into X/M M&#xd7;Y pixel subframes. Other embodiments are described and claimed.

Apparatus and method for hardware-based video/image post-processing

A method and apparatus for hardware-base edge handling in video post-processing. In one embodiment, the method includes the identification of at least one unstored input pixel required to compute an output pixel during output pixel computation. Once identified, a pixel value is generated for the at least one unstored input pixel according to a detected edge handling mode. The generation of the pixel value for the unstored input pixel is performed, in one embodiment, if a position of the unstored input pixel is outside a pixel frame boundary. For example, in one embodiment, for output pixel computation of a scaling operation, the frame boundaries include a left (top) edge and a right (bottom) edge for which input pixels required to compute output pixels at or near the frame boundaries do not exist. Other embodiments are described and claimed.

Apparatus and method for edge handling in image processing

Disclosed is an integrated circuit that includes clock generation circuitry which generates a master clock signal and at least one other clock signal. The master clock signal and the other clock signal are transmitted through a clock distribution tree to a circuit component. In a default mode, the circuit component receives the master clock signal at a first component block to create a first time domain for the first component block and receives the other clock signal at a second component block to create a second time domain for the second component block. Bypass logic creates a bypass path to allow the second component block to receive the master clock signal such that the clock domain of the second component block is the same as the clock domain of the first component block such that signals can be transferred between the clock domains with reduced latency.

Dynamically reconfiguring clock domains on a chip

According to one embodiment of the invention, a method is provided in which memory requests from a first component and a second component are received. The memory requests are issued by the first component and the second component to access one or more memory devices via a memory controller. The memory requests received from the first component are accumulated in a first queue and the memory requests received from the second component are accumulated in a second queue, respectively. The memory requests accumulated in the first queue are sent to the memory controller for processing as a block of memory requests. The memory requests accumulated in the second queue are sent to the memory controller for processing as a block of memory requests.

Apparatus, method, and system for reducing latency of memory devices

An embodiment of the present invention includes first and second storage elements. The first storage element stores request information transmitted from a first processor operating at a first frequency. The first and second processors operate at different frequencies. The request information is organized according to a request format. The second storage element stores response information transmitted by a second processor operating at a second frequency different than the first frequency in response to the request information. The response information is organized according to a response format.
