No. You can build unending loops (infinite loops)
But additional instructions are needed for
A conditional branch instruction branches to a new address only if a certain condition is true. Usually the condition is about the values in two registers.
Here is the
(branch on equal) instruction:
beq u,v,addr # if register $u == register $v # PC <— addr # (after a delay of one machine cycle.) # else # no effect.
The bit patterns in two registers are compared. If the bit patterns are the same, the PC is changed to the branch address. There is a branch delay slot that follows this instruction (just as for a jump instruction).
Do the bit patterns in the two registers represent integers?
