基于FPGA的离散量接口控制器设计
Design for discrete magnitude interface controller based on FPGA
摘要
Abstract
The application and requirement of discrete magnitude digital circuits are increased extremely in the avionics sys-tems,but the traditional discrete magnitude interface chips have low integration and high power dissipation,and the stability and reliability of discrete magnitude couldn't be guaranteed. According to the above situations,a new discrete magnitude inter-face convention chip is introduced,which can convert the 28 V aircraft power supply level into TTL level. It has wide applica-tion prospect because of its high integration,low power dissipation,and stable performance in severe environment. A control method different from the traditional"CPU + dedicated chip"methods is proposed,in which the field programmable gate array (FPGA)is used to control the discrete magnitude interface chip,the VHDL is adopted to compile the control logic,the Xilinx integrated development environment is employed to synthesize the design,and the test code is compiled for simulation. The simu-lation results show that the method can perform the read-write control of the chip,improve the data processing ability of the sys-tem,and has high stability and reliability.关键词
