MIPS – assembly BEQ command
MIPS – assembly BEQ command
beq $11, $0, 3 means jump to the third instruction ahead from beq if $11 == $0. For instance:
beq $11, $0, 3
instruction 1
instruction 2
instruction 3 < the target
the number 3 will be first sign extended and then added to the program counter $pc as:
$pc = $pc + 3 * 4
or simply:
$pc = $pc + 3 << 2
the 4 is because every MIPS instruction is 4 bytes size.
