Assembly Language Part-I

welcome to chapter three in this chapter we will cover assembly language which is the vital link between the hardware and software ah just to retreat this is chapter three of the book computer organizational architecture and the slides are meant to be used along with the book otherwise the learning will remain incomplete so let's first discuss in

the overview of assembly language subsequently we will discuss the syntax of a assembly language we will design a simple assembly language of our own called the simple risc assembly language along with ah it's instructions in the instruction set architecture subsequently we will move on to functions and stacks an advanced concept in assembly

language and we will discuss the encoding so let's fist define what is an assembly language so in assembly language is a low level programming language ah so we will discuss what is high level and what is low level so ah a low level programming language uses very very simple statements where typically one statement corresponds to a single machine instruction so these languages

are specific to the instruction set architecture and so for example c or java can be ah can run on any kind of a processor however ah as an assembly language is specific to only a particular process or a particular family of processors for example it is possible to run c ah let's move to the different media for example it is possible to run a c program

on both an intel machine and arm machine however intel has it's separate assembly language syntax and arm as it's separate assembly language syntax so so we will we will discuss what it is so c is a high level language because a concepts are at a very very high and abstract level and also this is a c program a single statement in the c program can actually be
