基于WCET的SPM实时性管理策略
SPM Real-time Performance Management Strategy Based on WCET
摘要
Abstract
This paper proposes a WCET-based static allocation algorithm for Scratch-Pad Memory(SPM), the algorithm obtains the Worst-Case Execution Path(WCEP) through an external Worst-Case Execution Time(WCET) estimation tool. According to the WCETP, the algorithm transforms the application into a directed graph consisting of nodes and relationships of nodes. It applies an algorithm which takes the relationships of nodes into account to solve the problem of SPM memory allocation. Simulation experiments show that the algorithm achieves an improvement of about 54％ in the real-time performance, compared to system without SPM.关键词
