Introduction - Software Development Tools Overview
The following list describes the tools that are shown in Figure 1 -1.
•
The C compiler accepts C source code and produces TMS34010 as-
sembly language source code. The C compiler has three parts: a pre-
processor, a parser, and a code generator. Section 3 describes compiler
invocation and operation.
•
The assembler translates assembly language source files into machine
language object files.
•
The archiver allows you to collect a group of files into a single archive
file. (An archive file is called a library.) It also allows you to modify a
library by deleting, replacing, extracting, or adding members. One of the
most useful applications of the archiver is to build a library of object
modules. Two object libraries and a source library are included with the
C compiler:
flib.lib contains floating-point arithmetic routines.
rts.lib contains standard runtime-support functions.
rts.src contains the source for the functions in rts
.lib.
Several application-specific object libraries are available as separate GSP
products:
The math/graphics function library contains math functions
for performing algebraic, trigonometric, and transcendental oper-
ations as well as graphics functions for performing viewport man-
agement, bit-mapped text, graphics output, color-palette control,
three-dimensional transformations, and graphics initialization.
The font library contains a variety of proportionally spaced and
monospaced fonts. You can use the functions in the graphics li-
brary to display the fonts.
The CCITT data compression function library contains
CCITT -compatible routines for compressing and decompressing
monochrome image data.
The
8514
adaptor emulation function library contains rou-
tines for use with the IBM PS/2 high-resolution display.
'
These functions and routines can be called from C programs. You can
also create your own object libraries. To use an object library, you must
specify the library name as linker input; the linker will include the library
members that define any functions called from a C program.
•
The linker combines object files into a single executable object module.
As the linker creates the executable module, it performs relocation and
resolves external references. The linker accepts relocatable COFF object
files and object libraries as input.
•
The main purpose of this development process is to produce a module
that can be executed in a
TMS3401 0
target system. You can use one
of several debugging tools to refine and correct your code. Available
products include: a software simulator that runs on PCs, a PC-based
software development board (SOB), and a realtime in-circuit
XDS/22 emulator.
•
An object format converter is also available; it converts a COFF ob-
ject file into an Intel, Tektronix, or TI-tagged object-format file that can
be downloaded to an EPROM programmer.
