Chapter 1 Setting Up the Code Generation Tools With DOS or Windows 3.1x This chapter helps you install release 1.20 of the TMS470R1x code generation tools and set up your code-development environment on a 32-bit x86-based or Pentium PC running MS-DOS, PC-DOS, or Windows 3.1x. These tools include an optimizing C compiler and a full set of assembly language tools for developing and manipulating assembly language and object (executable) code. The C compiler tools are composed of the following compo

Installing the Code Generation Tools 1.2 Installing the Code Generation Tools This section helps you install the code generation tools on your hard-disk system. The code generation tools package is shipped on CD-ROM. The installation instructions vary according to your operating system. Installing the tools on DOS systems To install the tools on a DOS system, follow these steps: 1) Insert the TMS470R1x Code Generation Tools CD-ROM into your CD-ROM drive. 2) Change to the CD-ROM drive (where d: i

Setting Up the Code Generation Environment 1.3 Setting Up the Code Generation Environment Before or after you install the code generation tools, you can define environ- ment variables that set certain software tool parameters you normally use. An environment variable is a special system symbol that you define and associate to a string. A program uses this symbol to find or obtain certain types of information. When you use environment variables, default values are set, making each individual invo

Setting Up the Code Generation Environment Identifying the directory that contains the executable files (PATH statement) You must include the tool_dir directory in your PATH statement so that you can specify the assembler and compiler tools without specifying the name of the directory that contains the executable files. If you modify your autoexec.bat file to change the path information, add the following to the end of the PATH statement: ;c:\tool_dir If you set the PATH statement from the c

Setting Up the Code Generation Environment Setting default shell options (C_OPTION) You might find it useful to set the compiler, assembler, and linker shell default options using the C_OPTION environment variable. If you do this, the shell uses the default options and/or input filenames that you name with C_OPTION every time you run the shell. Setting the default options with the C_OPTION environment variable is useful when you want to run the shell consecutive times with the same set of option

Setting Up the Code Generation Environment Specifying a temporary file directory (TMP) The compiler shell program creates intermediate files as it processes your program. By default, the shell puts intermediate files in the current directory. However, you can name a specific directory for temporary files by using the TMP environment variable. Using the TMP environment variable allows use of a RAM disk or other file systems. It also allows source files to be compiled from a remote directory with

Performance Considerations Performance Considerations / Where to Go From Here 1.4 Performance Considerations You may notice a speed degradation when you use the code generation tools with DOS or Windows 3.1x. This speed degradation may occur when you use DOS with the tools to get appropriate host memory support. If you encounter error messages when you use the tools on a PC with DOS, run PMINFO to determine your system configuration before you contact tech- nical support. For more information ab
