In a method of automatically identifying a format of a video signal, where the video signal includes HSync pulses, VSync pulses, and video display data, the video signal is received, information about timing and width characteristics of the HSync pulses and the VSync pulses is extracted from the video signal, and the format of the video signal is determined based on the extracted information.

Described herein is a method and system for multiplier optimization. A gate count savings that does not introduce additional quantization error can be achieved with this method and system. By increasing the number of digits in a multiplication result, partial products within a multiplication can be truncated. When the multiplication result is used in a subsequent operation, the gates required for the increased number of digits in the multiplication result can be made less than the gates saved within the multiply.

A system, device and method are disclosed for predicting the opacity of primitives used to produce an image using one or more equations, prior to producing an image. More specifically, the present invention relates to a 3D device adapted to produce an image comprising an opacity estimate predictor adapted to predict opacity of at least one primitive using at least one first equation and further adapted to reject the primitive if the predicted opacity is equal to a minimum value.

In a method and system for component sync detection and alignment, the Y/G channel is used as a master channel from which the vertical and the horizontal syncs are detected by a master sync generator. The master sync generator determines a fast and slow slice level for generating a rough and a fractional detection of the vertical sync and the horizontal sync and also generates a master sync timing window signal. A slave sync generator aligns the Pb/B and Pr/R channels to the Y/G channel by making use of the vertical, horizontal, and timing window sync signals produced by the master sync generator and by generating a slave slice level to detect the vertical and horizontal syncs in the slave channels. Positional differences in the alignment between the master channel and the slave channels are determined and stored for use in subsequent frame alignment.

Provided is a system and method for performing CRC analysis in a video test bench. An exemplary system includes a memory configured for storing a required number representative of the data fields to be analyzed. A module is coupled at least indirectly to the memory and configured for (i) receiving an input data stream, (ii) performing cyclic redundancy check (CRC) analysis of the received data stream, and (iii) producing an output representative of an actual number of received data fields analyzed. The input data stream includes synchronization markers defining boundaries of each of the received data fields. Next, a comparator is configured for (i) comparing the required number and the actual number and (ii) producing a disabling signal when the actual number matches the required number. A detector is coupled to the comparator and configured for (i) receiving the input data stream and sensing a presence of the synchronization markers, (ii) receiving the disabling signal, and (iii) disabling the CRC module when the disabling signal is received.
