The system uses the TMS320DM6437 DSP chip as the processor to build the software platform of image collection process system. The allover function of system can be divided into four relatively independent tasks, tasks of image collection, image processing tasks, data communication tasks and human-computer interaction tasks. this task operate according the previously configured priority scheduling in the TI DSP/BIOS, and inter-task synchronization and communication via semaphores, message mailboxes, this improve the utilization of the system resources. Eventually, the system achieve the transplantation of a variety of image processing algorithms, real-time data communications and interactive interface PC can reasonable, and the whole system has good stability and rapid real-time characteristics. 【KeyWords】DSP/BIOS; Image process platform; Thread scheduling 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc353830231 摘 要 PAGEREF _Toc353830231 \h II HYPERLINK \l _Toc353830232 Abstract PAGEREF _Toc353830232 \h III HYPERLINK \l _Toc353830233 目 录 PAGEREF _Toc353830233 \h IV HYPERLINK \l _Toc353830234 1
