1. Los是一个c/c++语言编译型的虚拟机。它使用llvm/clang作为其前端，losld做后端对源代码进行编译，生成los指令文件。Los虚拟机是100%c语言编写的，其可运行在mcu与pc上。 los(核心)占rom 8Kb左右(mini)。 los提供统一的api接口，实现一次编写，到处运行的好处，提高代码可重复使用率。 Author's mailbox:[email protected];QQ:708745662

        los.exe

1. 将bin文件添加到系统环境,进入los-mini文件夹内
2. 执行clang编译:clang -c test.c 与losld -o test test.o,生成test.los文件，将test.los文件转换为test[]数组
3. 在los-mini文件夹下，输入make命令，生成los.exe文件。运行观看结果

1.mini版本los，只有以下api：具体使用请看los.h文件内注释,以及参考test.c main.c

uint32_t los_quit(losc_t *lp);
void los_arg_clear(losc_t *lp);
uint32_t los_push_arg(losc_t *lp, uint32_t arg);
uint32_t los_call_addr(losc_t *lp, uint32_t addr);
void los_set_function(fun_os f);
uint32_t los_app_first(uint8_t *addr);

1. 需要把los.h的内存管理函数实现

#define lpram_malloc malloc
#define lpram_free free

1. 运行单个文件，请使用 xxx/los.exe xxx/xx.los的格式运行,或把los后缀的文件，拖到los.exe。
2. 运行losfat中的文件可以直接双击los.exe,它会已losfat的文件作为跟目录

• 现提供1个方式
  1. 使用makefile

• 现提供2个方式-注意把bin文件夹加入系统变量

1. 使用eclipse-build-los
2. 在mf-build-los-app夹中使用使用make命令

1. 不需要管理app功能的，请使用los_app_frist函数作为入口。如los_app_frist("c://test/test.los"),运行rom或ram中的los文件，请使用如los_app_frist("c://test/test@123456") 123456是los在rom或ram中的地址

2. 在arch文件中复制一份los_api文件夹，把各文件的api实现。

3. los的库，在lib文件中

English Language

1. Los is a c/c++-compiled virtual machine. It uses llvm/clang as its front end, and losld does the backend to compile the source code to generate the los directive file. The Los virtual machine is written in 100% c language and runs on mcu and pc. Los (core) accounts for about rom 8Kb (mini). Los provides a unified API interface to achieve the benefits of writing once, running everywhere, and improving code reusability. Author's mailbox: [email protected].

1. Add the bin file to the system environment and enter the los-mini folder.
2. Execute clang compilation: clang -c test.c     With losld -o test test.o, generate the test.los file and convert the test.los file to the test[] array.
3. In the los-mini folder, type the make command to generate the los.exe file. Run the viewing result

1.mini version los, only the following api: please see the comments in the los.h file for specific use, and refer to test.c main.c

Uint32_t los_quit(losc_t *lp);
Void los_arg_clear(losc_t *lp);
Uint32_t los_push_arg(losc_t *lp, uint32_t arg);
Uint32_t los_call_addr(losc_t *lp, uint32_t addr);
Void los_set_function(fun_os f);
Uint32_t los_app_first(uint8_t *addr);

1. Need to implement the memory management function of los.h

#define lpram_malloc malloc
#define lpram_free free

1. To run a single file, run it in xxx/los.exe xxx/xx.los format, or drag the s suffixed file to los.exe.
2. Run the file in losfat and you can double-click los.exe directly, it will be the losfat file as the directory

• 1 way available now    Use makefile

   * Now provide 2 ways - pay attention to add bin folder to system variables    1. Use eclipse-build-los    2. Use the make command in the mf-build-los-app folder

1. If you don't need to manage the app function, please use the los_app_frist function as the entry. For example, los_app_frist("c://test/test.los"), run the los file in rom or ram, please use los_app_frist("c://test/test@123456") 123456 is los in rom or ram the address of

2. Copy a los_api folder in the archive file and implement the api for each file.

3. los library, in the lib file
