摘要： A device and method for compensating for delays of a plurality of communication channels, provides signals with a certain frequency range, wherein the signals form standing waves in the plurality of communication channels; calculates phase differences between the plurality of communication channels according to the signal frequencies at the peak values of the standing waves; and determines the delay of each communication channel according to the above phase differences. The device and method may be applied to the communication channels of high speed parallel connection to eliminate the delays of the communication channels and realize length matching. Since the device and method determine the delays of communication channels by means of the phase differences, even when the delay difference exceeds a clock cycle, it can calculate the phase differences properly.

摘要： A filter and method of filtering modifies the computation order to accommodate horizontal symmetric filtering, and modifies the source operands while modifying the SIMD computation, so as to eliminate such heavy overhead of transposing a pixel matrix. The filter and method of filtering reformats the equations involved in the prior art to the following equations, thereby acquiring the interpolation results by reducing the required clock cycles to three cycles: acc=a0*(|p0+p5|p1+p6|p2+p7|p3+p8|) acc=a1*(|p1+p4|p2+p5|p3+p6|p4+p7|)+acc acc=a2*(|P2+P3|P3+P4|P4+P5|P5+P6|)+acc
