Description
Summary:碩士 === 國立交通大學 === 資訊工程學系 === 86 === In this thesis, we study some techniques for achieving maximum performance in pipelines. A task once initiated into a pipeline, flows from segment to segment for its execution. A collision occurs if two or more tasks attemptto use the same segment at the same time. Traditional methods like usingshift register or reduced state diagrams can avoid collisions, but they can not achieve maximum performance sometimes. By adding delays within thepipeline, it is always possible to attain maximum performance. We will describe some methods that can solve this problem. These methods areimproved and implemented. We use an approximate solution obtained by aheuristic algorithm as a bounding function in the Branch and Bound algorithmto find the optimal solution. It can drastically reduce execution time by reducing the number of generated nodes. By experiments, we will show the effects of changing bounds. For another method, we extend the applicationdomain from a single- function pipeline to a multi-function pipeline. In addition, we formulate an integer linear program to find the optimal solution.
