嵌入式系统下交叉汇编器的移植

Cross assembler porting in embedded systems

在芯片设计时,汇编器GAS应用越来越广泛。在分析GAS的数据类型和工作机制的基础上,根据目标处理器的特点和要求,对GAS进行了移植,为ZSP芯片开发出符合自由软件基金标准的汇编器,且ZSP芯片的体系结构体现了芯片的普遍结构,具有可推广性,促进其在嵌入式系统下的应用。

While designing new chips, the application of assembler GAS becomes increasingly wide. Based on the analysis of data type and working mechanism of GAS, the GAS was transplanted to develop a new assembler according to the characteristic and requirement of the target processor. The new assembler is suitable for the foundation standard of free software for the new processor ZSP. It also has a common architecture which appeared in some other DSP chips, and it is able to facilitate the application of GAS in the embedded system.
