Description
Function
Insert Bit Field
Rt = InsertField(Rs, Rt, pos,
size)
Unconditional Jump
PC = PC[31:28> || offset<<2
Jump and Link
GPR[31> = PC + 8
PC = PC[31:28> || offset<<2
Jump and Link Register
Jump and Link Register with Hazard Barrier
Rd = PC + 8
PC = Rs
Like JALR, but also clears execution and
instruction hazards
Jump and Link Register Compact – do not execute
instruction in jump delay slot (MIPS16e™ only)
Rd = PC + 2
PC = Rs
Jump Register
PC = Rs
Jump Register with Hazard Barrier
Like JR, but also clears execution and
instruction hazards
Jump Register Compact – do not execute instruction in PC = Rs
jump delay slot (MIPS16e only)
Load Byte
Rt = (byte)Mem[Rs+offset>
Unsigned Load Byte
Rt = (ubyte))Mem[Rs+offset>
Load Halfword
Rt = (half)Mem[Rs+offset>
Unsigned Load Halfword
Rt = (uhalf)Mem[Rs+offset>
Load Linked Word
Rt = Mem[Rs+offset>
LL = 1
LLAdr = Rs + offset
Load Upper Immediate
Rt = immediate << 16
Load Word
Load Word, PC relative
Rt = Mem[Rs+offset>
Rt = Mem[PC+offset>
Load Word Left
See Architecture Reference Manual
Load Word Right
See Architecture Reference Manual
Multiply-Add
HI | LO += (int)Rs * (int)Rt
Multiply-Add Unsigned
HI | LO += (uns)Rs * (uns)Rt
Move From Coprocessor 0
Rt = CPR[0, Rd, sel>
Move From HI
Rd = HI
Move From LO
Rd = LO
Move Conditional on Not Zero
if Rt ¼ 0 then
Rd = Rs
Move Conditional on Zero
Multiply-Subtract
if Rt = 0 then
Rd = Rs
HI | LO -= (int)Rs * (int)Rt
Multiply-Subtract Unsigned
HI | LO -= (uns)Rs * (uns)Rt
Move To Coprocessor 0
CPR[0, n, Sel> = Rt
Move To HI
HI = Rs
Move To LO
LO = Rs
Multiply with register write
Integer Multiply
HI | LO =Unpredictable
Rd = ((int)Rs * (int)Rt)_31..0
HI | LO = (int)Rs * (int)Rd
Unsigned Multiply
HI | LO = (uns)Rs * (uns)Rd
