.1553 B Bus Rt Interface Board Design

This paper introduce the topologies of avionics communication system, transfer protocol of the data bus and the kernel of designing the avionics system through thestudy of the development of avionics communication sytem in the world. Emphasizing on the introduction of a new design scheme of "1553B BUS Multi-RT Interface Board".The theory and implementing method of Digital Signal Processing(DSP) has gained a very much rapid rise, and has become one of the most growing technology in this world. For it's rapid Signal Processing and powerfull and flexible interface and communication ability, it has been used in a lot of area.With the advancement of technology and craftwork, the devolpment of the technique of Integrated Circuit(IC) has made it posibble to integrate a Programmable System On a Chip(SOPC). Among all of these, because it's flexible design method and high speed , "Field Programmable Gate Array" (FPGA) has been widely used in many digital design of Application Specific Integrated Circuit.The core of this paper is DSP and FPGA. This paper introduce the principle of the "1553B Bus Multi-RT Interface Board" ,the design of hardware and software, emphasizing on the inner part of FPGA which fulfill the function of the transmision and reception of 1553B BUS data and other function part. Through software simulation, this paper also give a demonstration to the design.
