Abstract

This paper introduces a flexible code generation framework dedicated to the design of application specific programmable processors. This tool allows the user to build specific compilation flows, using a library of modules, implementing flexible compilation passes such as code generation, resource allocation, scheduling, etc. Retargeting is performed at two levels: minor changes in the target processor architecture are handled by a retargeting of the modules of the defined compilation flow, while major modifications require a structural modification of the flow. To build a compiler for a target processor, the user selects modules from the library, and links them together. While the global compiler structure is user-defined, the retargeting of modules is automatically performed by the framework. Target processors are described using ARMOR, a programmable processor modeling language especially defined for design space exploration. The proposed tool is then suitable for a large range of instruction set architectures.
一个灵活的代码生成框架,用于设计特定于应用程序的可编程处理器
本文介绍了一个灵活的代码生成框架,专门用于设计特定应用的可编程处理器。该工具允许用户使用模块库构建特定的编译流,实现灵活的编译过程,如代码生成、资源分配、调度等。重定向是在两个级别上执行的:目标处理器体系结构中的微小变化通过对已定义编译流的模块进行重定向来处理,而主要的修改则需要对流进行结构修改。要为目标处理器构建编译器,用户需要从库中选择模块,并将它们链接在一起。虽然全局编译器结构是用户定义的,但是模块的重定向是由框架自动执行的。目标处理器使用ARMOR描述,这是一种专门为设计空间探索而定义的可编程处理器建模语言。因此,所提出的工具适用于大范围的指令集架构。
