微结构描述语言CHMDL的构造与设计

CONSTRUCTION AND DESIGN OF THE MICROARCHTTECTURE LANGUAGE CHMDL

本文介绍微结构描述语言CHMDL的构造与设计.该语言对可微程序设计体系结构的计算机微结构的描述具有较大的选择性与灵活性.特别,它把对微结构的描述程序转换成为一种称为“表状微结构”的表格驱动式的中间代码形式,为其支持完整的可重定向固件开发工具,提供了统一的微结构描述形式.另外,本文对MDL的构造,编译结果及评价标准等作了讨论.

Construction and design of the machine-independent microarchitecture description language CHMDL are introduced in this paper. CHMDL, which can describe any microarchitecture of microprogrammable processors, translates the source description into a table-like structure which is called Table-formed Microarchitecture. CHMDL is used to support fireware development for fireware tools in FDE. Construction, result of compiling and performance of MDL are also discussed in the paper.
