Star sensor is a special high accuracy photoelectric sensor. Attitude acquisition time is an important function index of star sensor. In this paper  the design target is to acquire 10 samples per second dynamic performance. On the basis of analyzing CCD signals timing and star image processing  a new design and a special parallel architecture for improving star image processing are presented in this paper. In the design  the operation moving the data in expanded windows including the star to the on-chip memory of DSP is arranged in the invalid period of CCD frame signal. During the CCD saving the star image to memory  DSP processes the data in the on-chip memory. This parallelism greatly improves the efficiency of processing. The scheme proposed here results in enormous savings of memory normally required. In the scheme  DSP HOLD mode and CPLD technology are used to make a shared memory between CCD and DSP. The efficiency of processing is discussed in numerical tests. Only in 3.5ms is acquired the five lightest stars in the star acquisition stage. In 43us  the data in five expanded windows including stars are moved into the internal memory of DSP  and in 1.6ms  five star coordinates are achieved in the star tracking stage.
