Dsp/Bios Configuration Tool - Texas Instruments C28 Series Student Manual

DSP/BIOS Configuration Tool

The DSP/BIOS Configuration Tool (often called Config Tool or GUI Tool or GUI) creates and
modifies a system file called the Configuration DataBase (.CDB). If we talk about using CDB
files, we're also talking about using the Config Tool.

The GUI (graphical user interface) simplifies system design by:
•
Automatically including the appropriate runtime support libraries
•
Automatically handles interrupt vectors and system reset
•
Handles system memory configuration (builds CMD file)
•
When a CDB file is saved, the Config Tool generates 5 additional files:
Filename.cdb
Filenamecfg_c.c
Filenamecfg.s28
Filenamecfg.cmd
Filenamecfg.h
Filenamecfg.h28
When you add a CDB file to your project, CCS automatically adds the C and assembly
(.S28) files to the project under the Generated Files folder. (You must manually add the
CMD file, yourself.)
