Focusing on the special working method of interference hyper-spectral imaging instrument,satisfying the real-time spectrum reconstruction study of interference image, based on hyper-spectral reconstruction arithemetic, a system of hyper-spectral data was established.In this paper,a solution of parallel image processing system based on multi-DSP of ADSP-TS101 is put forward and implemented on hardware.Presently,the system achieves interference hyper-spectral image reconstruction on multi-channels on CPCI.Moreover, it establishes the technology foundation for researching hyper-spectral data applying.satisfying the image bandwidth of 70Hz,satisfying real-time requestThis paper mainly descriped the actualize of spectrum instrument on hardware bench,the difficulty is to satisfy the realtime require of 70Hz frame frequency.the mainly content include:1,descriped hyper-spectral imaging theory,and hyper-spectral imaging instrumentreconstruction theory and method,2,To satisfy the real-time spectrum reconstruction,we had to choose multi-DSP parallel hardware system,based on that,we choose multi-DSP parallel hardware system,mainly include the follow parts:;DSP parallel connect,this part is the most importent of the system,include DSP connect to the PCI bus and the Link port connection of the DSPs;There are abundance of SDRAM in the hardware system, in addition a FPGA data play board was need.and so on.Good hardware equipment supply good condition to the software design.3,Software system design,include the package of reconstruction core arithmetic,main DSP program design, the receving and the realtime roll displaying of reconstruction image on PC.4,After the hole designing of hardware and software completed,we had to do sometest on the system to asure it work by expected.The innovation of this paper:1,The study of fast arithmetic on hardware of super spectrum imagereconstrustion.2,The study of multi parallel signal processing technique,and multi DSP parallel technique.
