ori - correct answer ori $t, $s, imm
bitwise ORs a register ($s) and an immediate value (imm) ---> stores the result in a register ($t)
( loads $t with imm, if $s =$0 )
$t = $s | imm; advance_pc (4);
ex:
ori $8,$0,0x2
#put two's comp. t...
bitwise ORs a register ($s) and an immediate value (imm) ---> stores the result in a register ($t)
( loads $t with imm, if $s =$0 )
$t = $s | imm; advance_pc (4);
ex:
ori $8,$0,0x2
#put two's comp. two into register 8
ori $9,$0,0x3
#put two's comp. three into register 9
bitwise opertation - correct answer operates on one or more bit patterns or
binary numerals at the level of their individual bits, good for comparisons and calculations
bitwise ORs - correct answer compares two bit patterns and performs OR
operation--->results in each position is 0 if both bits are 0, otherwise 1
bne - correct answer bne $s, $t, offset
branch not equal; if $s != $t advance_pc (offset << 2)); else advance_pc (4);
slti - correct answer (signed)
slti $t, $s, imm
, if $s < imm, then $t=1
else if $s > imm, then $t=0
sw - correct answer sw $t, offset($s)
store word; $t is stored in the address $s
-offset is a constant that is added to the register in brackets
MEM[$s + offset] = $t;
lw - correct answer lw $t, offset($s)
word is loaded into a register from the specified address
$t = MEM[$s + offset]
word - correct answer 4 bytes or 32 bits
all instructions are 32 bits or one word
byte - correct answer 8 bites
halfword - correct answer 2 bytes
stack grows - correct answer grows from high memory to low memory
.data - correct answer -declare variable names used in program
