| Abstract: | To reduce the time spent on trajectory and data calculation and improve the quick reaction of weapon,the trajectory and data calculation software was analyzed via Intel Vtune.Combined with the characteristic of trajectory and data calculation model,the hotspot and the part with good parallelizability in the classical model of trajectory and data calculation were studied.The trajectory and data calculation software was improved and realized through the thread pool.The simulation proved this arithmetic can ef... |
