Abstract

This paper addresses the real-time optimization problem to find the most efficient and reliable message chain structure in data communications based on half-duplex command–response protocols such as MIL-STD-1553B communication systems. This paper proposes a real-time Monte Carlo optimization method implemented on field programmable gate arrays (FPGA) which can not only be conducted very quickly but also avoid the conflicts with other tasks on a central processing unit (CPU). Evaluation results showed that the proposed method can consistently find the optimal message chain structure within a quite small and deterministic time, which was much faster than the conventional Monte Carlo optimization method on a CPU.

Summary

Introduction

In the field of aerospace and defense, MIL-STD-1553B [1], which is a well-known military data communication standard based on half-duplex command–response protocols, has been widely used communication standard based on half-duplex command–response protocols, has been widely used as as data communication systems. It defines the mechanical, electrical, and functional characteristics of data communication systems. The impact of a short circuit can be reduced by coupling coupling transmitters and receivers to the bus through isolation transformers and by using a pair transmitters and receivers to the bus through isolation transformers and by using a pair of isolation of isolation resistors for stub connections to branch off. In the application layer, application layer, the available bandwidth is limited because the da ta transmission is constrained the available bandwidth is limited because the data transmission is constrained by the required by the required time for data processing in remote terminals
