assembly language instructions format

How do I read an assembly instruction?
This is the typical way to read an assembly instruction. Add R2 to R1 and put it (the result) in R0. The equivalent machine code that will execute on the processor is shown alongside the ADD instruction. The 'Cond' field contains '1110' for always execute. These bits come into play when using conditional suffixes appended to the ADD operation.
What are the common features of assembler?
Although each Assembly Instruction Format has its own unique syntactical structure, such as requiring upper case or lower case, or requiring colons after label definitions we discuss the common features that assembler shares. The assembly text is usually divided into fields, separated by spaces and tabs.
What are instruction formats?
In computer organization, instruction formats refer to the way instructions are encoded and represented in machine language. There are several types of instruction formats, including zero, one, two, and three-address instructions.
What is the format for a typical line in assembly language?
A format for a typical line from assembly language program can be given as The first field, which is optional, is the label field, used to specify symbolic labels. A label is an identifier that is assigned to the address of the first byte of the instruction in which it appears.

Declaring Static Data Regions

Example declarations: Unlike in high level languages where arrays can have many dimensions andare accessed by indices, arrays in x86 assembly language are simply anumber of cells located contiguously in memory. An array can be declaredby just listing the values, as in the first example below. Two othercommon methods used for declaring arrays of dat
