What is__ asm NOP?
7 Answers. 7. nop is an assembly instruction that does nothing–well as close to nothing as you can do and still execute a machine instruction, which means (probably) a REALLY tiny bit of time goes by (which can have limited value in certain realtime applications.
What is NOP () in C?
In computer science, a NOP, no-op, or NOOP (pronounced “no op”; short for no operation) is a machine language instruction and its assembly language mnemonic, programming language statement, or computer protocol command that does nothing.
What does NOP do?
The NOP instruction does nothing. Execution continues with the next instruction. No registers or flags are affected by this instruction. NOP is typically used to generate a delay in execution or to reserve space in code memory….NOP.

What is NOP in arm?
Usage. NOP does nothing. If NOP is not implemented as a specific instruction on your target architecture, the assembler treats it as a pseudo-instruction and generates an alternative instruction that does nothing, such as MOV r0, r0 (ARM) or MOV r8, r8 (Thumb). NOP is not necessarily a time-consuming NOP .
How long does a NOP operation take?
2 Answers. The NOP instruction takes one cycle in most microprocessors, so do the math: e.g., on a 8 MHz processor, one cycle takes 1 / 8 MHz = 125 ns. You then have to add few cycles more for the management of the loop.
What is NOP in finance?
NOP stands for Net Operating Profit, also known as NOI (Net Operating Income). It is a KPI / calculation of Net Operating Income / profit after subtracting all of the operating expenses from the revenues generated by a hotel.
How long is a NOP?
What does NOP do in MIPS?
NOPs. A NOP is an instruction that does nothing (has no side-effect). MIPS assembler often support a nop instruction but in MIPS this is equivalent to sll $zero $zero 0 . This instruction will take up all 5 stages of pipeline.
What does Lea do in assembly?
The lea instruction places the address specified by its first operand into the register specified by its second operand. Note, the contents of the memory location are not loaded, only the effective address is computed and placed into the register.
What is the meaning of no op?
no operation
The term No-op (NOP) stands for “no operation”. It is a computer science term for related code that is used when the programmer wishes to move to the next consecutive instruction. It can also be used as a “placeholder” for instructions or “timing” purposes.
How is NOP calculated?
What is NOI in hotels?
NOI, which stands for net operating income, is the amount of money left after you have paid out all of your expenses. It’s a profitability metric that shows you how well a hotel operates, from both a total revenue standpoint and total expenses standpoint. You may also see this metric as net operating profit, or NOP.
Is the ASM declaration allowed in mikroC pro?
The mikroC PRO for dsPIC30/33 and PIC24 allows embedding assembly in the source code by means of the asm declaration. The declarations _asm and __asm are also allowed in the mikroC PRO for dsPIC30/33 and PIC24 and have the same meaning.
Can a mikroC pro be used in embedded assembly code?
The mikroC PRO for dsPIC30/33 and PIC24 comments (both single-line and multi-line) are allowed in embedded assembly code. The only types whose name remains the same in asm as it is in the mikroC PRO for dsPIC30/33 and PIC24 are registers, e.g. INTCON, PORTB, WREG, GIE, etc.
Can a declaration of asm be used in PIC24?
The declarations _asm and __asm are also allowed in the mikroC PRO for dsPIC30/33 and PIC24 and have the same meaning. Note that numerals cannnot be used as absolute addresses for SFR or GPR variables in assembly instructions. Symbolic names may be used instead (listing will display these names as well as addresses).
Which is the only type whose name remains the same in ASM?
The only types whose name remains the same in asm as it is in the mikroC PRO for dsPIC30/33 and PIC24 are registers, e.g. INTCON, PORTB, WREG, GIE, etc. Depending on the place of declaration, accessing a variable can be done in several ways : 1.
