Abstract:
1. An apparatus for motion search refinement, the apparatus comprising: a row register configured to store a row of pixels from a (J+L+J)×(J+L+J) pixel window, wherein L is a number of the form 2 a first 2J-tap filter configured to operate on the pixels in the row register to produce row results that are interleaved with row pixels selected from the row register to form interpolated row results; a transpose storage unit configured to store the interpolated row results and configured to read the stored interpolated row results in transpose order to be written to pipelined registers as column pixels; and a second 2J-tap filter configured to operate on the column pixels selected from the pipelined registers to produce column results that are interleaved with column pixels selected from the pipelined register stages to form interpolated column results.
