The MIPS instruction set is very small, so to do more complicated tasks we need to employ assembler macros called pseudoinstructions.. List of Pseudoinstructions . The following is a list of the standard MIPS instructions that are implemented as pseudoinstructions
MIPS parameters. All MIPS instructions are 32-bits. To ease the writing of assembly instructions given this restriction, the MIPS assembler allows pseudoinstructions, which appear to be simple instructions, but, instead generat Instruction Operands Description; add: d,s,t: d <-- s+t ; with overflow trap addu: d,s,t: d <-- s+t ; without overflow trap addi: d,s,const: d <-- s+const ; with overflow trap const is 16-bit two's com MIPS has a section of addresses where you can store data and call upon it at a later time (if you are using the pcSPIM MIPS simulator, the 'memory' range starts at 10000000). there is, however, a delay time when it comes to loading or storing information in the memory Opcode The 6-bit opcode of the instruction. In I instructions, all mnemonics have a one-to-one correspondence with the underlying opcodes.

The MIPS processor supports two conditional branches: beqz (branch if equal to zero) and bnez (branch if not equal to zero). Both these instructions take an arbitrary register as a source operand.

These instructions are identified and differentiated by their opcode numbers (any number greater than 3). All of these instructions feature a 16-bit immediate, which is sign-extended to a 32-bit value in every instruction (except for the and, or, and xor instructions which zero-extend and the lui instruction in which it does not matter) [mips][microMIPSr6] Implement NOR, OR, ORI, XOR and XORI instructions.

Accessing Array Data in MIPS. Since arrays can store LOTS of data, and since we have only a small (~32) number of registers, it is infeasible to use the registers for long-term storage of the array data. Hence, arrays are stored in the Data Segment of a MIPS program. Fundamentally, there are three operations which one can perform on an array Learning MIPS & SPIM • MIPS assembly is a low-level programming language • The best way to learn any programming language is to write code • We will get you started by going through a few example programs and explaining the key concept Load Immediate. The ori instruction, used as above, copies a bit pattern from the instruction into the destination register. (Recall that the 16 bit immediate operand is zero-extended into 32 bits.) This operation is usually called a load immediate operation — it loads a register with a value that is immediately available (without going to memory)

In effect, the assembler supports an extended MIPS architecture that is more sophisticated than the actual MIPS architecture of the underlying hardware. Of course, the assembler must be able to translate every pseudo-instruction.
