The exact number of iterations in each phase depends on the scale and nature of the project. The UP phase illustration here contains exactly 1, 2, 4 and 2 iterations in the four phases, but this is merely an example of how a specific project could look.
1: add 1 to R5 2: copy R5 to R6 If the processor has the 5 steps listed in the initial illustration (the 'Basic five-stage pipeline' at the start of the article), instruction 1 would be fetched at time t 1 and its execution would be complete at t 5. Instruction 2 would be fetched at t 2 and would be complete at t 6.
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development.It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management.
In simpler CPUs, the instruction cycle is executed sequentially, each instruction being processed before the next one is started. In most modern CPUs, the instruction cycles are instead executed concurrently, and often in parallel, through an instruction pipeline: the next instruction starts being processed before the previous instruction has finished, which is possible because the cycle is ...
Program lifecycle phases are the stages a computer program undergoes, from initial creation to deployment and execution. The phases are edit time, compile time, link time, distribution time, installation time, load time, and run time. Lifecycle phases do not necessarily happen in a linear order, and they can be intertwined in various ways.

Pipelining allows different functional units of a system to run concurrently. Consider an informal example in the following figure. A system includes three sub-function units (F 0, F 1 and F 2). Assume that there are three independent tasks (T 0, T 1 and T 2) being performed by these three function units. The time for each function unit to ...
Programming involves activities such as analysis, developing understanding, generating algorithms, verification of requirements of algorithms including their correctness and resources consumption, and implementation (commonly referred to as coding [1] [2]) of algorithms in a target programming language.
