Abstract

A new method of data access which can effectively resolve the problem of high speed and real time reading data of nuclear instrument in small storage space is introduced. This method applies the data storage mode of “linked list” to the system of Micro Control Unit (MCU), and realizes the pointer access of nuclear data on the small storage space of MCU. Experimental results show that this method can solve some problems of traditional data storage method, which has the advantages of simple program design, stable performance, accurate data, strong repeatability, saving storage space and so on.

Highlights

  • People have a large demand for real time processing data rapidly and the rapidity with nuclear instrument in recent years

  • According to the above problems, this design has designed a data storage method based on the “chain link”, which can realize the reasonable utilization of the small storage space of Micro Control Unit (MCU) without adding any external memory

  • In our design of nuclear instrument, the processor uses 8-bit microcontroller to control and store the data sent by the nuclear signal acquisition

Summary

Introduction

People have a large demand for real time processing data rapidly and the rapidity with nuclear instrument in recent years. Most of the traditional methods use Micro Control Unit (MCU) as a processor for real-time processing of data. External data storage is commonly used in the traditional method in order to prevent data loss, reduce the occupation time, and improve the working efficiency of nuclear instrument [1]. This method will increase the design cost of nuclear instrument, and increase the complexity of the hardware circuit, which is not conducive to the maintenance of the instrument.
