Abstract

This paper presents a method of constructing the sequential digital systems over finite fields. We assign all elements in finite fields to digit codes using mathematical properties of finite fields. Also, we discuss the operational characteristics and properties of the building block T-gate which is used to implement the sequential digital systems over finite fields. Then, we implemented sequential digital systems without feed-back. The sequential digital systems without feed-back is constructed as following steps. First, we assign the states in state-transition diagram to state digit codes, then obtain the state function and predecessor table which is explaining the relationship between present states and previous states. Next, we obtained the next-state function from state function and predecessor table. Finally we realize the circuit using T-gate and decoder. The proposed method is more efficiency and systematic than previous method.

본 논문에서는 유한체상의 순차디지털시스템을 구성하는 방법을 제안하였다. 제안한 방법은 유한체의 성질로 부터 유한체상의 모든 원소를 디지트코드로 할당하는 알고리즘을 제안하였고, 유한체상의 순차디지털시스템을 구성하는데 사용하는 T-gate의 동작특성에 대해 논의하였으며, 이를 토대로 궤환이 없는 순차디지털시스템을 구성하였다. 이를 위해 상태천이도를 상태디지트코드로 할당하였고, 상태함수와 현재상태와 이전상태와의 관계를 나타내는 전순표를 도출하였다. 다음에 상태함수와 전순표로부터 다음상태함수를 도출하였으며, 이를 T-gate와 복호기를 시용하여 순차디지털시스템을 구성하였다. 제안한 방법으로 효과적이고 체계적으로 순차디지털시스템을 구성할 수 있었음을 확인하였다.
