DESIGN MODELS OF BIT-STREAM IRRATIONAL FUNCTION ONLINE-COMPUTER

Abstract

Topicality. Currently, in distributed real-time control systems it is necessary to ensure continuous reception and processing of information data streams as they arrive. In this case, the current task is to create stream computers that perform functional conversion of signals of sensor components, presented in the form of a pulse stream. The purpose of this work is to develop mathematical and automata design models for a bit-stream online-computer of irrational functions with a pulse (bit) data stream. The object of research is hardware bit-stream computers of irrational functions, the basis of which is the streaming method of calculations. The subject of the study are models and methods for designing bit-stream online-computers of irrational functions. Results. An improved mathematical model of a device for calculating irrational functions using the stepwise approximation method based on inverse functions and an automatic model of the computer based on Moore's finite state machine are proposed. Conclusion. The use of the proposed design models of a streaming computer allows minimizing the absolute error of calculations and increasing the efficiency of device design through the use of developed HDL templates for describing the computer model.
