Instruction Set

3.4.6.26 JGE

JGE Jump if greater or equal

Syntax JGE label

Operation If (N .XOR. V) = 0 then jump to label: PC + 2 P offset → PC

If (N .XOR. V) = 1 then execute the following instruction

Description The status register negative bit (N) and overflow bit (V) are tested. If both N and V are

set or reset, the 10-bit signed offset contained in the instruction LSBs is added to the

program counter. If only one is set, the instruction following the jump is executed.

This allows comparison of signed integers.

Status Bits Status bits are not affected.

Example When the content of R6 is greater or equal to the memory pointed to by R7, the program

continues at label EDE.

CMP @R7,R6 ; R6 >= (R7)?, compare on signed numbers

JGE EDE ; Yes, R6 >= (R7)

...... ; No, proceed
