Abstract: Aim To study the fast display algorithm for graphics and image,and to develop an object oriented class library used for Motif under aworkstation environment Methods A high performance VHDL wave viewer is developed on a workstation using C ++ and Motif A three level mapping display algorithm is used in the wave viewer Results The algorithm has the characteristics of having a fast display speed and is easily transplanted Conclusion Superiority of the algorithm is fully demonstrated and the rationality of the design of class library approved
