Cross assembler porting in embedded systems
嵌入式系统下交叉汇编器的移植

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.
