QUESTION 2:
Fill in the blanks so the branch is taken if $rs is zero.
______ rs,________,label # branch to label if register rs == 0
A conditional branch
tests a condition then changes the PC if the condition is true
(for example, the instruction beq label).
The extended assembler implements several conditional branch instructions beyond the basic ones. For example:
beqz rs,label # branch to label if register rs == 0
# (pseudoinstruction)
The hardware does not have a machine instruction for this
operation.
It does, however, have a zero register and the
beq instruction (branch equal).
Fill in the blanks so the branch is taken if $rs is zero.
______ rs,________,label # branch to label if register rs == 0
