special hardware
3.According to the feature of the graphics of EADI,a new design scheme of the graphics display system based on a new structure of double frame buffer alternation and edge flag filling algorithm with special hardware is introduced. The scheme sets up three different flags for the character and boundary of sky and ground, takes corresponding operation dependeding on flags with special FPGA hardware,and realizes the rapid region filling and superposition of character.
5.On the basis of computer network system structure and normal network safety system, this paper analyzes safety factors in network, gives 4 to 7 layers new safety techniques according to OSI reference model of computer network system structure, introduces GAP information safety new technique utilizing special hardware to make two networks realize data transmission and resource share under unconnected condition. On this basis, this paper summarizes the development trend of network safety.
7.A kind of virtual instrument used for on-line measurement of dielectric loss tangent of capacitive type equipment is presented in this paper. It is based on a special self-designed hardware and CVI software development tool, and breaks through the limit of traditional instrument on data processing, transmission, displaying and saving etc.
