To exploit the concept of pipelining in computer architecture many processor units are interconnected and are functioned concurrently. The performance of a simple pipe, the physical speed limitation, and the control structures for penalty-incurring events are analyzed separately. In pipelined processor architecture, there are separated processing units provided for integers and floating point instructions. These. C. Pipelining increases the overall performance of the CPU. Some amount of buffer storage is often inserted between elements.. Computer-related pipelines include: . Arithmetic Pipeline in Computer Architecture . The elements of a pipeline are often executed in parallel or in time-sliced fashion. CPI: Pipeline yields a reduction in cycles per instruction. Let us see a real life example that works on the concept of pipelined operation. The dependencies in the pipeline are called Hazards as these cause hazard to the execution. Every stage performs partial processing of the task that it is supposed to do. Example: " Computer architecture refers to hardware instructions, software standards and technology infrastructure that define how computer platforms, systems and programs operate. The pipeline architecture consists of multiple stages where a stage consists of a queue and a worker. One of these concepts is called pipelining and it is used in several ways in pretty much every computer nowadays.
