What does JG mean in assembly?
Jump if Greater
The command JG simply means: Jump if Greater.
What does Jae mean in assembly?
Jump if above or equal
jae means Jump if above or equal. It will jump if the carry flag is equal to 0.
What are the assembly instructions?
The instructions included with a product to show visually and with words and text how to assemble the product. Assembly instructions are a vital part of a product that requires self assembly e.g. self assembly furniture.
What is the difference between Ja and JG?
As Intel’s manual explains, JG interprets the flags as though the comparison was signed, and JA interprets the flags as though the comparison was unsigned (of course if the operation that set the flags was not a comparison or subtraction, that may not make sense). So yes, they’re different.
What is JB Assembly?
The JB instruction branches to the address specified in the second operand if the value of the bit specified in the first operand is 1. The bit that is tested is not modified. No flags are affected by this instruction. See Also: JNB.
What are the four different types of instructions assembly?
Types of Assembly Languages
- Assembly language closely tied to processor architecture. At least four main types:
- CISC: Complex Instruction-Set Computer. RISC: Reduced Instruction-Set Computer.
- DSP: Digital Signal Processor. VLIW: Very Long Instruction Word.
What is Ja x86?
ja means “jump if Carry Flag unset and Zero Flag unset”. The cmp instruction is really the same as the sub instruction (i.e. it subtracts its arguments), except that the result is not saved but only the condition flags are updated.
What is MOV stand for?
MOV
| Acronym | Definition |
|---|---|
| MOV | QuickTime Movie (file extension) |
| MOV | Metal Oxide Varistor |
| MOV | Move/Movement |
| MOV | Move |
How do I use MOV instructions?
The MOV instruction is the most important command in the 8086 because it moves data from one location to another….The MOV instruction.
| destination | source | example |
|---|---|---|
| register | immediate | mov ax,10h |
| register | memory | mov ax,es:[bx] |
| memory | immediate | mov aNumber,10h |
| memory | register | mov aDigit,ax |
What does MOV instruction do?
The mov instruction copies the data item referred to by its second operand (i.e. register contents, memory contents, or a constant value) into the location referred to by its first operand (i.e. a register or memory). While register-to-register moves are possible, direct memory-to-memory moves are not.
What is JG instruction in C?
Description The jg instruction is a conditional jump that follows a test. It performs a signed comparison jump after a cmp if the destination operand is greater than the source operand
What is the meaning of JG command in a processor?
The command JG simply means: Jump if Greater. The result of the preceding instructions is stored in certain processor flags (in this it would test if ZF=0 and SF=OF) and jump instruction act according to their state. Thanks for contributing an answer to Stack Overflow!
How do you combine conditional jumps in Assembly?
You can combine nearly any jump statement without its j-prefix to a single j and gain a new jmp statement. Take for instance the following example: jnle – jump if not less than or equal (the same as jg) These conditional jumps allow for loops and if statements in Assembly language.
What does JG mean in JB?
Note how in this particular example the signedness mattered, e.g. JB is taken but not JL. Runnable example with assertions. Opcode Instruction Description 7E cb JLE rel8 Jump short if less or equal (ZF=1 or SF ≠ OF). 7E cb JNG rel8 Jump short if not greater (ZF=1 or SF ≠ OF). Show activity on this post. The command JG simply means: Jump if Greater.
