Abstract
The Space Solar Telescope(SST) can reach 0.1" in the spatial resolution to meet the demand of observation on solar magnetic field. The correlation tracker can stable the output image during the CCD exposure time. In order to correct the error signal, whose frequency is less than 100Hz, the fast correlation calculation device is needed. In this paper, a new method, which can short the computing delay to 0.3ms, is introduced. It is fit for the demand of SST.
