Which of the following is not a program control instruction?

Which of the following is not a program control instruction? Correct Answer MOV

Concept:

MOV, a mnemonic for the copying of data from one location to another in the x86 assembly language

Program control instruction help in changing the flow of a program. Program control types are an unconditional branch or unconditional jump and conditional branch. 

Explanation:

Branch is a small change in the program counter. The conditional jump can implement algorithms beyond simple formulas. Various types of program control instructions are :

Compare:

This instruction is helpful in performing a comparison. It does not store results. CMP is used to compare

Subroutines:

It is a subprogram that performs a specific and well-defined task. Example: CALL and RET.

Halting instruction:

It takes the processor to an idle state when an interrupt occurs. Example: HLT

Interrupt instruction:

By this, the normal flow of execution can be suspended. Example: RESET, TRAP etc.

Therefore MOV is not a program control instruction

A 5-stage pipelined processor has Instruction Fetch (IF), Instruction Decode (ID), Operand Fetch (OF), Perform Operation (PO) and Write Operand (WO) stages. The IF, ID, OF and WO stages take 1 clock cycle each for any instruction. The PO stage takes 1 clock cycle for ADD and SUB instructions, 3 clock cycles for MUL instruction, and 6 clock cycles for DIV instruction respectively. Operand forwarding is used in the pipeline.

At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions: 1. If program P is to be operated on a day, V can’t be operated on that day. 2. If Q is to be operated on a day, T must be one of the programs to be operated after Q. 3. If R is to be operated on a day, V must be one of the programs to be operated after R. 4. The last program to be operated on any day must be either S or U. If the program sets R and W are to be operated on the first day, which of the following could be the other program on that day?
Which of the following is/are the advantages of using a control chart for inspection? (i) A control chart indicates whether the process is in control or out of control. (ii) A control chart determines process variability. (iii) A control chart ensures product quality. (iv) Scrap or percentage reduction can be reduced by taking the necessary actions in time against the warnings indicated by control charts. (v) Control charts build up the reputation of the organization through customer’s satisfaction. (vi) The control chart can detect the unusual variations taking place in a process.
On a non-pipelined sequential processor, a program segment, which is a part of the interrupt service routine, is given to transfer 500 bytes from an I/O device to memory.     Initialize the address register     Initialize the count to 500 LOOP: Load a byte from device     Store in memory at address given by address register     Increment the address register     Decrement the count     If count! = 0 go to LOOP Assume that each statement in this program is equivalent to a machine instruction which takes one clock cycle to execute if it is a non-load/store instruction. The load-store instructions take two clock cycles to execute. The designer of the system also has an alternate approach of using the DMA controller to implement the same transfer. The DMA controller requires 20 clock cycles for initialization and other overheads. Each DMA transfer cycle takes two clock cycles to transfer one byte of data from the device to the memory. What is the approximate speedup when the DMA controller based design is used in place of the interrupt driven program based input-output?
With reference to 8085 microprocessor, which of the following statements are correct? 1. The DAD instruction adds the contents of the specified register pair to the contents of the DE register pair 2. The program counter is an instruction pointer 3. Whenever an instruction uses the HL pointer, the addressing is called indirect addressing. 4. HL register pair is also called data pointer
A portion of the main program to call a subroutine SUB in an 8085 environment is given below. \(\begin{matrix}:\\\ :\\\ \rm LXI&\rm D,DISP\\\ \rm LP:\ \ \ \ \ CALL\ \ \ \ \ \ \ \ \ &\rm SUB\ \ \ \ \ \\\ :\\\ :\end{matrix}\) It is desired that control be returned to LP + DISP + 3 when the RET instruction is executed in the subroutine. The set of instructions that precede the RET instruction in the subroutine are:
The instruction given to a computer system is loaded into the Instruction Register. The processor interprets the instruction and performs the required action. In general, these actions fall into four categories. Which of the following actions is not a part of these four categories? 
Which of the following statements is/are not true about the "Grid Organisation Development" (Grid OD) Program designed by Robert R. Blake and Jane S. Mouton?
1. It is a eight phase program lasting about three to five years.
2. Through this program, an organisation can move systematically from the stage of examining managerial behaviour and style to the development and implementation of an "ideal strategic corporate model".
3. Behavioural science concepts and rigerous business logic are combined in the Grid OD Program's six phases.
4. The single most significant premise on which Grid OD rests in that the 5, 5 way of doing business which is acknowledged universally by managers as the soundest way to manage to achieve excellence.
