Using DSP/BIOS in Driver Development of the Image Fusion System Based on DM 642

In the paper the method and flow of driver development are described using the real-time multi-threading operating system DSP/BIOS and image fusion algorithms on the independent development image fusion system based on TMS320DM642.The TI techniques,such as BIOS,chip support library(CSL),board support library(BSL),driver development kit(DDK),reference frameworks level 5(RF5),expressDSP algorithm standard(XDIAS),etc,are employed synthetically to develop the device driver.The standard class/mini-driver model is used to develop the new video driver.It makes the modularization and hiberarchy of development realizable.On the bais the fusion algorithms are programmed and the optimization techniques in CCS programming are summarized.Compared with traditional software development,the driver development based on DSP/BIOS shortens development time and increases compatibility,inherited attribute and portability.
