A threaded or chained pipeline is a series of processing elements (PEs) connected together by FIFO queues. The first PE in the pipeline reads data from an input FIFO queue, processes the data, and writes the results to an output FIFO queue. The output FIFO queue of the first PE is connected to the input FIFO queue of the second PE, and so on. The last PE in the pipeline writes the results of its processing to an output FIFO queue.
Threaded or chained (us) is a type of pipeline that is used in computer architecture. It is used to improve the performance of the processor by allowing multiple instructions to be executed at the same time. The processor will fetch and decode the first instruction while the second instruction is being executed. This process is repeated until all instructions have been executed.
The advantage of using a threaded or chained pipeline is that it allows the PEs to operate in parallel. The first PE can begin processing the data while the second PE is still reading the data from the input queue. This can increase the throughput of the system.
The disadvantage of using a threaded or chained pipeline is that it can introduce delays. For example, if the first PE is much faster than the second PE, the second PE will have to wait for the first PE to finish writing the data to the output queue before it can begin processing. This can reduce the overall throughput of the system.
Threaded or chained pipelines are used in a variety of applications where multiple processes are required to work together in order to complete a task. In many cases, these processes can be executed in parallel, which can greatly improve the efficiency of the overall system.
Threaded or chained pipelines can be found in a wide variety of industries, including manufacturing, computer science, and even medicine. In each of these fields, the use of pipelines can help to speed up the completion of tasks and improve the overall efficiency of the system.
