Low I/O bandwidth and high throughput architecture design of motion estimation
Lei Xu · Computer Engineering and Applications Journal · 2009
Full search architecture is popular in motion estimation of video coding.Unfortunately,calculating by conventional 1-D、 2-D systolic array or tree architecture will result in high I/O bandwidth,low efficiency.Using data-interlacing method,a new data flow and corresponding two-dimensional systolic array are proposed.They can efficiently reuse data to decrease I/O bandwidth with high throughput.Simulation shows that it can get 41 MVs in 256 cycles with only 3 I/O data ports.
