What is the difference between directive, instruction and pseudo-instruction for an assembly language?
What is the difference between directive, instruction and pseudo-instruction for an assembly language?
Homework Answers
Instruction:
It is a kind of mnemonic which can be mapped into binary code directly by translating opcode and operand.
Pseudo-instruction:
It is not an real instructions in Instruction Set Architecture. it
exists only in the assembler and will produce real instructions
once it is completed the assembling
Ex; LDR R0
Directive:
It also exist only in the assmebler but after assmbleing also does
not create any machine code just it will instruct the assembler how
to perform certain tasks
