关于计算机研究的理论框架

一、引言计算机的研究始终离不开理论模型作为背景。计算问题、计算机语言问题、程序设计问题以及计算机体系结构问题,无不建立在相应的模型之上。

Computational model,programming paradigm,and execution mechanism are often heard terminologies in different contexts among researchers of computing technology, especially in AI community. The meaning of them seem varying from context to context .sometimes cause confusion. In this work,we are trying to clarify these concepts and give a general framework to unify them. In particular, we are proposing a hierarchical structure with four layers computational model,computing model (including calculus model and operational model),programming paradigm, and computer model (including abstract machine and execution mechanism),and discussing the relationship between them.
