摘要: 隨著應用層面的多元化,現今的電子系統必須要能同時執行多種不同的應用,並符合整體效能的要求。當系統設計架構逐漸朝著高度整合之多核心結構發展的同時,系統中的傳輸資源也同時要能支援不同的系統應用特性。多核心系統中傳輸資源的主要功能是要有效地將重要的資訊在不同的核心及記憶元件之間傳遞。但若是不了解應用特性而盲目地設計傳輸資源及其相關架構,會造成整體系統效能無法針對應用的特性作最佳化,包含資源使用效率,功耗效率,及系統複雜度等。為了要達到最佳的效能,系統傳輸資源的設計必須要與應用層面的特性結合,來做整體的考量。 此計畫的主要目標為針對特殊應用之多處理器系統中可重置化傳輸資源之設計及最佳化。本計畫將會根據應用之特性,採用由上而下,跨設計層級的方法,來達到傳輸資源最佳化的目的。本計畫將傳輸資源分成三個部分進行分析及設計,分別為程式設計介面,資源管理方案,以及相對應的傳輸硬體架構。此三項研究重點分布在不同的設計層,因此需要跨層級的軟硬體協同設計以達到最佳化的效能。 本計畫預計執行的時間為三年。第一年將會建立一套多核心系統模型,包含軟體及硬體模組,以支援整體效能的分析及驗證。此外也將探討不同設計層中的傳輸資源之元件特性及設計參數。第二年主要目標為建立一可重置化傳輸資源的原型,並連結各設計層之間的設計參數以及彼此間的效應。針對應用本身的特性,我們也將歸納出跨設計層之間的設計考量點。第三年將致力於整體系統的整合,並配合其他子計畫的規格,對多核心系統的可重置化傳輸資源提出一有效的設計方法。
With the flourish of diverse applications, modern electronic devices are required to support a variety of system specifications defined by various application domains. As the system architecture is moving towards the multi-core scheme, the system not only demands to be highly integrated, its communication resources also have to meet diverse requirements. The communication resources are responsible for effectively transporting necessary data between processing cores and memory unit within a system. However, blindly invest the communication resource without knowing the executed application has been proved to be ineffective in optimizing resource utilization, energy efficiency, and system complexity. To attain the best performance, the design of the communication architecture and the resource management scheme need to take the characteristics of the executed application into consideration. The main goal of this project is to design and optimize the reconfigurable communication resources for application-specific multi-core systems. The key concept is to identify essential application characteristics and incorporate their impact to the design of communication resources. A top-down, cross-layer approach will be adopted to streamline the design methodology from application characterization, programming interface, communication resource coordination, to interconnect hardware architecture. This project will be executed in three years. The first year will implement a cross-layer multi-core system model to facilitate the feature analysis and result verification. The diverse design features, from application down to communication resources, will also be characterized. The second year will develop a prototype of reconfigurable communication resource. The other focus is to build links that enable the co-design and co-optimization across different layers. The third year will concentrate on integrating an overall system architecture and developing a design methodology.
