Question
1 RXY
LOAD the register R with the bit pattern found in the memory cell whose
address is XY.
2 RXY
LOAD the register R with the bit pattern XY.
3 RXY
STORE the bit pattern found in register R in the memory cell whose address
is XY.
4 ORS
MOVE the bit pattern found in register R to register S.
S RST
ADD the bit patterns in registers S and T as though they were two's
complement representations and leave the result in register R.
ADD the bit patterns in registers S and T as though they represented values
in floating-point notation and leave the floating-point result in register R.
6 RST
7 RST
OR the bit patterns in registers S and T and place the result in register R.
8 RST
AND the bit patterns in register S and T and place the result in register R.
9 RST
EXCLUSIVE OR the bit patterns in registers S and T and place the result in
register R.
A ROX
ROTATE the bit pattern in register R one bit to the right X times. Each time
place the bit that started at the low-order end at the high-order end.
B RXY
JUMP to the instruction located in the memory cell at address XY if the bit
pattern in register R is equal to the bit patterm in register number 0.
Otherwise, continue with the normal sequence of execution. (The jump is
implemented by copying XY into the program counter during the execute
phase.)
C 00
HALT execution.
