Branch

Fig. 5.10

Instruction provides read register numbers to register file, offset to sign extend

Registers give operand input to ALU for comparison (which ALU operation?)

ALU generates Zero output (what value?) to branch control

Sign extend provides 32-bit value to shifter, which shifts left by 2 bits

Adder computes branch target for possible PC update using:

Offset from shifter

PC + 4 from instruction datapath
