Embodiment Construction
[0034] The present invention will be further described below in conjunction with accompanying drawing.
[0035] see figure 1 , as can be seen from the figure, the two-way motion estimator of the present invention mainly includes:
[0036] The storage unit 10 caches the corresponding data in the two reference frames before and after in the form of stripes.
[0037] The matching error calculation unit 20 divides the interpolation frame into several rectangular macroblocks of the same size, sets the search range based on each macroblock, and calculates the data within the search range according to the data in the two frames of reference frames sent by the storage unit. Matching errors corresponding to all motion vectors; the matching error calculation unit is divided into two parts: parity array register 201 and PE unit 203 . Among them, the odd-even array register includes 4 sets of shift registers, which are respectively the even-numbered column data register of the previous ...
