Abstract

An extended zero-one linear programming (O/1 LP) model for the scheduling problem in high-level synthesis is presented. As an extension to former approaches, the 0/1 LP model can handle multifunctional function units as well as different execution times for different instances of the same operation type. These extensions are very important for the applicability of general high-level synthesis tools in real design tasks. The computing time for solving the optimization problems is also acceptable for the new powerful model, since new lower bounds have been introduced that drastically reduce the search space. Some experimental results are shown.<>

高级综合调度问题的扩展0/1 LP公式
针对高级综合调度问题,提出了一个扩展的0 /1线性规划(O/1 LP)模型。作为前一种方法的扩展,0/1 LP模型可以处理多功能功能单元以及同一操作类型的不同实例的不同执行时间。这些扩展对于一般高级综合工具在实际设计任务中的适用性非常重要。解决优化问题的计算时间对于新的强大模型来说也是可以接受的,因为引入了新的下界,大大减少了搜索空间。给出了一些实验结果。
