In this paper, we report on the development of a correlation tracker system for the New Solar Telescope (NST). It consists of three sub-systems: a tip-tilt mirror unit, a camera unit, and a control unit. Its software has been developed via Microsoft Visual C++, which enables us to take images from the high-speed CMOS camera in order to measure the image motions induced by atmospheric turbulence by using SAD algorithm and 2-D FFT cross-correlation, and to control the high-dynamics Piezo tip-tilt mirror for tip-tilt correction. We adopted the SIMD technology and parallel programming technology based on the Intel Core 2 Quad processor without any additional processing system (FPGA or DSP) for high-speed performance. As a result, we can make a tip-tilt correction with about seven hundreds of Hz in a closed loop mode. The prototype system has been successfully developed in a laboratory and will be installed on the NST.
