MOTION COMPENSATING CIRCUIT

摘要

The circuit minimizes capacity of memory for search window and can output sequentially a motion-compensated data from memory for search window. It comprises : (i) memories (M1˜M4) storing sequentially a search window data of previous frame to each unit block of present frame; (ii) a writing address generator(100) generating address for writing a common data among search window data on memory; (iii) a reading address generator(200) generating address for reading motion compensation data; (iv) a memory controll unit(300) controlling a memory read/write operation; (v) an address selection unit(400) supplying one output among the writing address generator and the reading address generator to memories; and (vi) an input/output buffer unit(500) supplying transmission path of input/output data.
