  2. In this paper, a high integrated and intelligent digital dsp - spm system is developed based on the nspm6800 spm manufactured by the beijing zhongke mechanical & electrical equipment co. at present, the pc of spm system is burdened with not only sending and receiving data, but also disposing of image, which hinders the enhancement of speed of the system. in addition, as the function of spm is expanding, including tappingmode afm, efm, mfm, scm, etc, one hand, it amplifies the range of the application of spm, on the other hand it also means that the task of autocontrol and data transfer heavier. the advantages offered by the dsp compared to analog systems include considerable flexibility in the choice of the signal processing algorithm and greater ease in managing control parameters by the host computer, which are very important for the improvement of spm
