Format :
BGEZ rs, offset
Description :
Generates a branch target address by adding the address of the instruction in the delay slot to the 16-
bit offset (that has been left-shifted two bits and sign-extended to 32 bits). If the sign bit of the
value in general-purpose register rs is 0 (i.e., the value is positive or 0), the program branches to the
target address after a one-cycle delay.
Operation :
T:

target ← (offset
