|Title:||FAST SINC INTERPOLATION METHOD AND SYSTEM|
Disclosed are a fast sinc interpolation method and system. The fast sinc interpolation method comprises: constructing a kernel function, wherein the kernel function comprises a plurality of thread blocks executed in parallel, the thread blocks comprise a plurality of threads executed in parallel, and the threads are used for sinc interpolation calculation of a sampling point (S10); starting and executing the kernel function, and one of the threads searching an interpolation kernel table pre-stored in the thread block to which the thread belongs to obtain a weighted value corresponding to one sampling point in a pre-set sample (S20); and according to the weighted value corresponding to the sampling point, carrying out sinc interpolation calculation on the sampling point to obtain an interpolation result of the sampling point, and after the kernel function is completely executed, obtaining interpolation results of all the sampling points in the pre-set sample (S30). By means of the method, the time for calculating an interpolation kernel in real time during the interpolation calculation process is saved on, an amount of calculation is reduced, and synchronous interpolation calculation of all the sampling points in a pre-set sample can be realised, thus increasing the interpolation processing speed.
