The colorimeter to high-speed heating or cooling with the function of high speed measurement process, measurement of the temperature value through FFT filtering processing send display or printing after. This paper firstly introduces the development status of temperature measurement instrument, and combined with extensive market research demonstrates the DSP chip in our country developed with high-speed colorimeter necessity and feasibility. Then in introduces the development and application of digital signal processor (DSP) the main field, DSP chip the structural characteristics and classification, based on the characteristics of high-speed highlighted. it system on the selection, and DSP chip TMS320F240 of selected chip -- the structure and features a detailed explanation. Then detail the colorimeter to achieve the function, in the colorimeter to achieve the function on the basis of the hardware of various parts are highlighted. it out the design and optimization. In the hardware design basis, using code debugger completed each part of the software design. This system would also explain the reason for the choice of other parts of a chip. Considering the system will achieve the function and choice, after the chip all parts of the system were given briefly diagram. Then explained the process of development of the syst
