Normally PC increments sequentially except for branch instructions. The arrows on either side indicate that the PC state element is both readable and writeable. The branch datapath (jump is an unconditional branch) uses instructions such as beq $t1, $t2, offset , where offset is a 16-bit offset for computing the branch opcode.

Please refer to the following figure. The datapath for a branch uses the ALU to evaluate the branch condition and a separate adder to compute the branch target as the sum of the incremented PC and the sign-extended, lower 16 bits of the instruction (the branch displacement), shifted left 2 bits.

The abstract behind the branch ISA's are that if the conditions are met, the program counter will JUMP to the given address. To implement a branch, the Branch generator must be correct and the PC source must be set to branch. To insure the PC source is correct, a control unit decoder must be able to differentiate between the commands.
