    • Abstract
  • After designing a navigation display data set(NDIS_SET)including several dimensions,a new parallel display algorithm with navigation data named N_PDIS is presented to adapt to embedded computation and memory limited resources.N_PDIS can choose one from two preparative bitmaps and switch to screen automatically through two parallel threads.After compared with normal navigation data display algorithm named NDIS,N_PDIS is shown more effective to improve display efficiency
