The first or only module of a program coded with the msp / 7library macros . this module must contain system routines required in every storage load , and can include system routines required by more than one module of the program 7的模块系统程序（ msp 7 ）库宏指令编码的程序的第一个或唯一一个模块，该模块必须包括每次存储装入所要求的系统例行程序，也可以包括多个程序模块所要求的系统例行程序。
Firstly the thesis introduces the frame and design of the c 、 c + + compiler , and discusses the implementation of the compiler based on gcc , which is a retargetable compiler . the implementation considers the architecture of thump , including the delay slots , the instruction interlock , macro expansion , and libraries for soft - float . and addresses the process developing the cross compiler and native compiler for thump 论文介绍了thump的c 、 c + +编译器的总体结构以及设计方案，并详细阐述了利用可重定向编译器gcc实现thump的c 、 c + +编译器的方法和过程，包括延迟槽修改、指令互锁的实现、宏指令展开以及软件浮点库的生成等，并实现了thump的交叉编译器和本地编译器。
