Power-architecture Description Language XP-ADL and Design Environment

降低计算机系统的功耗日益成为系统设计中的重要目标 ,可配置 VL IW体系结构在低功耗系统设计中具有显著的优势 .本文提出一种功耗 -体系结构描述语言 XP- ADL ,并介绍了基于该语言的体系结构设计环境 .XP- ADL语言将系统中各功能部件的结构表示和它们的执行 (功能 )语义分离开来 ,方便了可配置的 VL IW体系结构的描述 .同时 ,为了便于在功耗模型下进行体系结构空间探索 ,XP-

Low power is becoming as a critical design target in current system design. Reconfigurable VLIW architecture has apparent advantages for low power design. This paper presents an architecture description language XP ADL for low power design and its architecture design environment. This language is firstly utilized in VLIW architecture design in our approach. XP ADL facilitates the description of reconfigurability by distinguishing construction information and execution information of system function units when describing reconfigurable VLIW architecture. The language and its environment also support various power models and power constraints by integrating basic power statistics in its grammar, which greatly facilitates the low power architecture design space exploration.
