Directives are instructions to the assembler, specifying an action to be taken during the assembly process. One important use of directives is declaring or reserving memory variables. In addition, directives are used to break up the program into sections.
What are MIPS directives?
What are MIPS in programming?
The term MIPS is an acronym for Microprocessor without Interlocked Pipeline Stages. It is a reduced-instruction set architecture developed by an organization called MIPS Technologies. The MIPS assembly language is a very useful language to learn because many embedded systems run on the MIPS processor.
What are the five assembler directives?
Reserve space in memory for uninitialized variables. Control the appearance of listings. Initialize memory. Assemble conditional blocks.
What is MIPS in memory?
MIPS memory is byte-addressable, which means that each memory address references an 8-bit quantity. The MIPS architecture can support up to 32 address lines. ❖ This results in a 232 x 8 RAM, which would be 4 GB of memory. … The MIPS load byte instruction lb transfers one byte of data from main memory to a register.
What are Assembly directives?
Assembler directives are directions to the assembler to take some action or change a setting. Assembler directives do not represent instructions, and are not translated into machine code. … data directive tells the assembler that information that follows is program data.
How do I use MIPS program?

What is Li and La in MIPS?
When you'd use li and when you'd use la depends on the context. If the value you're loading is going to be used as an address you would typically use la to load it, and otherwise you'd typically use li .
What are assembler directives list any four assembler directives and its usage?

How many types of assemblers are there?
There are two types of assemblers based on how many passes through the source are needed (how many times the assembler reads the source) to produce the object file. One-pass assemblers go through the source code once.
