SCO设计中软硬件划分耗费函数的构造

Creation of Cost Function for HW/SW Partitioning in SOC

在片上系统(SOC)设计过程中,软硬件的划分是一个非常关键的问题,它是一个多目标的优化问题,直接影响了系统的性能。为寻求这个问题的最优解需要处理许多问题。如何构造耗费函数来向导划分过程达到系统的要求和限制就是其中一个非常重要的问题。本文将重点介绍耗费函数的构造方法及其原理,以及我们在这方面的一些有益探索。

SW/HW partitioning is a key problem during the process of SOC design, which directly affects performance of system. It's a multi-object optimization problem. Many problems must be tackled in order to find the best optimized solution. How to create the Cost Function to direct the process of partitioning to meet the requirement and limitation of system is one of the important problems. In this text, we will lay stress on the creation mathods of cost function and its princple, and introduce some useful explorations.
