What does SLTI do in MIPS?
SLTI — Set on less than immediate (signed) If $s is less than immediate, $t is set to one. It gets zero otherwise.
What are instructions in MIPS?
MIPS Instruction Formats
- All MIPS instructions are encoded in binary.
- All MIPS instructions are 32 bits long.
- All instructions have an opcode (or op) that specifies the operation (first 6 bits).
- There are 32 registers.
- There are three instruction categories: I-format, J-format, and R-format (most common).
- I-Format:
What does MIPS edition mean?
MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts. You won’t even feel a difference when wearing a MIPS-equipped helmet.
What type of instruction is SLTI?
Opcodes
| Mnemonic | Meaning | Type |
|---|---|---|
| slti | Set to 1 if Less Than Immediate | I |
| sltiu | Set to 1 if Less Than Unsigned Immediate | I |
| sltu | Set to 1 if Less Than Unsigned | R |
| sll | Logical Shift Left | R |
What are I-type instructions?
I-Type instructions, or Immediate instructions, can be either Load/Store operations, Branch operations, or Immediate ALU operations. In these instructions, one two register file locations are specified as well as a 16-bit immediate value which may be used as an operand or an address.
What is MIPS instruction give an example?
Arithmetic Instructions
| Instruction | Example | Meaning |
|---|---|---|
| add unsigned | addu $1,$2,$3 | $1=$2+$3 |
| subtract unsigned | subu $1,$2,$3 | $1=$2-$3 |
| add immediate unsigned | addiu $1,$2,100 | $1=$2+100 |
| Multiply (without overflow) | mul $1,$2,$3 | $1=$2*$3 |
What is Li and La in MIPS?
la stands for Load Address. It can be used to load integer constants just like li , e.g. la $t0,0x1234678 . But it also works with labels: la $t0, Message # t0 = address of Message . Some assemblers may also allow you to do things like la $t0, 8($t1) # t0 = t1 + 8 .
What is BLT in MIPS?
Branch Pseudoinstructions Branch if less than (blt) The blt instruction compares 2 registers, treating them as signed integers, and takes a branch if one register is less than another.
What processors use MIPS?
Five most iconic devices to use MIPS CPUs
- SGI Indigo (MIPS R3000) The SGI Indigo was a line of workstation computers created by Silicon Graphics (SGI).
- Sony PlayStation (MIPS R3000 CPU)
- Nintendo 64 (MIPS R4300i CPU)
- NEC Cenju-4 (MIPS R10000 CPU)
- Tesla Model S (MIPS I-class CPU)
Is MIPS big endian or little endian?
Since MIPS assumes a Big Endian organization, the book will label the MSB as bit 0, and the LSB as bit 31 in a word, and is bit 63 in a double word.
