摘要： The address generation unit 166 generates a write address for each picture data to be written in the frame memory 169. The memory control unit 165 writes picture data which have the same Y address and consecutive X addresses to the first bank and the second bank alternately per one-page mode length, and further writes picture data which have the same X address and adjacent Y addresses to the different banks. The memory control unit 165 determines a minimum area which consists of an odd number of page mode lengths and includes picture data of a square area having the same Y address, and reads the determined area from the two storage areas alternately per Y address.

摘要： A correlation computing device includes a higher-order bit elimination circuit which receives a digital input image signal and provides an output signal in which higher-order bits up to 50% have been eliminated as a maximum word length of a digital input image signal. A representative point preservation memory temporarily stores the output signal from the higher-order bit elimination circuit. A correlation determining circuit determines a correlation between a signal stored in the representative point preservation memory and the output signal from the higher-order bit elimination circuit. A minimum-value address decision circuit selects a minimum value of the correlation determined by the correlation determining circuit and determines a motion vector for the digital input image signal.

摘要： Systems and methods for reducing latency through motion estimation and compensation techniques are disclosed. The systems and methods include a client device that uses transmitted lookup tables from a remote server to match user input to motion vectors, and tag and sum those motion vectors. When a remote server transmits encoded video frames to the client, the client decodes those video frames and applies the summed motion vectors to the decoded frames to estimate motion in those frames. In certain embodiments, the systems and methods generate motion vectors at a server based on predetermined criteria and transmit the generated motion vectors and one or more invalidators to a client, which caches those motion vectors and invalidators. The server instructs the client to receive input from a user, and use that input to match to cached motion vectors or invalidators. Based on that comparison, the client then applies the matched motion vectors or invalidators to effect motion compensation in a graphic interface. In other embodiments, the systems and methods cache repetitive motion vectors at a server, which transmits a previously generated motion vector library to a client. The client stores the motion vector library, and monitors for user input data. The server instructs the client to calculate a motion estimate from the input data and instructs the client to update the stored motion vector library based on the input data, so that the client applies the stored motion vector library to initiate motion in a graphic interface prior to receiving actual motion vector data from the server. In this manner, latency in video data streams is reduced.
