Abstract:
The present invention utilizes determining the similarity between two adjacent frames to accelerate the computation of disparity maps of a stereo video. In a first stage, color similarity of pixels between the two adjacent frames is estimated. In a second stage, a plurality of feature points is selected from a previous frame, then the corresponding positions is located in a next frame for the feature points, and an average displacement of the feature points between the previous and the next frames is estimated. If the two adjacent frames are determined to be similar, the disparity map of the next frame can be obtained according to the disparity map of the previous frame. In such a manner, the computation of disparity maps of the stereo video can be accelerated.

Abstract:
For decreasing errors within an analog phase-locked loop, an all-digital phase-locked loop (ADPLL) with digital components and digital operations is used. The ADPLL may also be used for direct frequency modulation (DFM). By defining a proportional path gain of an ADPLL by a bandwidth and a reference frequency of the ADPLL, by a TDC gain, a DCO gain, a dividing ratio of a frequency divider, a gain of an amplifier or a combination thereof, the gain of the amplifier may be adjusted so that an optimal loop bandwidth of the ADPLL may be well calibrated. For achieving the aim of entirely digital of the ADPLL, the gains of the TDC and the DCO may be further adjusted in a digital manner.

Abstract:
The invention provides a wobble detection circuit. An exemplary embodiment of the wobble detection circuit comprises an automatic gain control module, an analog to digital converter, a digital band pass filter, and a digital band pass filter. The automatic gain control module amplifies a first input signal and a second input signal detected by a pickup head to the same magnitude to obtain a first amplified signal and a second amplified signal. The adder then subtracts the second amplified signal from the first amplified signal to obtain an analog wobble signal. The analog to digital converter then converts the analog wobble signal to a first digital wobble signal. Finally, the digital band pass filter accepts frequency components of the first digital wobble signal within a pass band and rejects frequency components of the first digital wobble signal outside the pass band to obtain a second digital wobble signal.
Abstract:
A virtual hint based data cache way prediction scheme, and applications thereof. In an embodiment, a processor retrieves data from a data cache based on a virtual hint value or an alias way prediction value and forwards the data to dependent instructions before a physical address for the data is available. After the physical address is available, the physical address is compared to a physical address tag value for the forwarded data to verify that the forwarded data is the correct data. If the forwarded data is the correct data, a hit signal is generated. If the forwarded data is not the correct data, a miss signal is generated. Any instructions that operate on incorrect data are invalidated and/or replayed.
