Suppose an instruction takes 4 cycles to execute in an unpipelined CPU: one cycle to fetch the instruction, one cycle to decode

the instruction and fetch any operands, one cycle to perform the ALU operation, and one cycle to store the result. In a CPU with a 4 stage pipeline, that instruction still takes 4 cycles to execute, so how can we say the pipeline speeds up the execution of the program?

Answer: Instruction pipelining is a technique for implementing instruction level.

Pipeline speeds up the execution of a program by increasing the Central Processing Unit throughout (Number of instructions completed per unit time). The increase in instruction throughput means that a program will run faster with a lower total execution time.

Is the address 7b invalid regarding cell references?
Lubov Fominskaja [6]

Answer:

It is not valid

Explanation:

I'll assume the question relates to cell referencing in Microsoft Excel.

To reference a cell in Excel, we make use of the following steps:

  • Write out the cell column name first
  • Followed by the row number

7b implies that, the row number first, followed by the column name; this doesn't follow the naming convention of cells.

Hence, 7b is invalid.
