The Intel 8085 microprocessor in current education

Abstract

The Intel 8085 Microprocessor launched on the market in 1976, as a substantial improvement to the Intel 8080 Microprocessor, but keeping its essential features in terms of its set of instructions in assembly language, caused a great impact in the scientific
and commercial field of that time. In our study, the Intel 8085 was chosen because it is one of the most prominent and important ancestors of modern Intel Core i3, Intel Core i5, Intel Core 19, Intel Core i10 microprocessors, widely used worldwide in desktop and laptop computers. all types. But given the complexity of these modern microprocessors, we were forced to go back in time and evoke the simplicity of one of these ancestors, the Intel 8085, which with its 8-bit architecture allows us to scrutinize its most intimate secrets in an easier and more entertaining and thus be able to understand how its internal operation really is, reaching the very essence of programming, using Machine Language with its hexadecimal format to later simulate it. In this article we will make a brief introduction to the Intel 8085, we will see its internal architecture, we will give reasons why it is currently used, to finally go on to analyze a program.
