Jumpking instructions

Then jump if the condition is true or continue if it is false. Conditional jump instructions can be divided into four groups: 3. Jumps based on the value of a single arithmetic flag. Unconditional jumps Jump Jump instructions near the target label is in the same segment than the jump far jump to another code segment Direct jump jmp label Near jump jmp Stop xor. J Instructions Jxx - Jump Instructions Table Mnemonic JA JAE JB JBE JC JCXZ JE JG JGE JL JLE JMP JNA JNAE JNB JNBE JNC JNE JNG JNGE JNL JNLE JNO JNP JNS JNZ JO JP JPE JPO JS • The JMP instruction tells the CPU to "Jump" to a new location. This is essentially a goto statement. We should load a new IP and possibly a new CS and then start executing code at the new location. Two groups of instructions: • branches • conditional transfers of control • the target address is close to the current PC location • branch distance from the incremented PC value fits into the immediate field Conditional jumps for the 8051 are summarized in Table 3-1. More details of each instruction are provided in Appendix A. In Table 3-1, notice that some of the instructions, such as JZ If a jump instruction was executed, the program counter will be modified to contain the address of the instruction that was jumped to and program execution continues normally. All conditional jumps are short jumps, as in that the address of the target must be within -128 to -127 bytes of the contents of the program counter [PC]. Unconditional Jump Instructions Wall Instructions. As filler under poles, or stand-alone. Use 2 or 1 section for a "skinny" jump. I started with 3 4-foot long solid pallets much like this. (Two similar pallets were made into the castle wall jump instruction (branch instruction) See jump. Source for information on jump instruction: A Dictionary of Computing dictionary.
