浮点加法的SystemC设计

Design Arithmetic of Float Adder in SystemC

以IEEE754标准格式中的单精度格式为标准,进行浮点加法器的设计。SystemC作为一种基于C++语言的新型硬件设计语言比较原有的HDL语言在系统级建模、软硬件协调设计方面更具优势,因此也更适用于SoC的设计建模。通过对浮点加法流程的分析,以其算法设计和结构映射为例,对浮点加法步骤加以讨论,得出合适于标准格式的设计,并结合如何应用SystemC进行系统设计,给出浮点加法器部分模块的SystemC描述。

Based on single -floating IEEE754, the float adder to build the system model by using HDL（hardware design language is designed. The traditional method is ）, but the efficiency is low and not fit to SoC （ system on chip） design. As a new hardware design language based on C ＋＋ language, SystemC is more suitable for system level design than HDL. Based on the flow of float adder, Algorithm design and the structure mapping with the floating adder is the instance, talked about how design system in SystemC, moreover give out floating adder part of module of SystemC to depict.
