Expert Linker Overview

Expert Linker Overview
Expert Linker is a graphical tool that allows you to:
• Define a DSP target's memory map
• Place a project's object sections into that memory map
• View how much of the stack or heap has been used after running
the DSP program
Expert Linker takes available project information in an .
(object files, LDF macros, libraries, and target memory description) and
graphically displays it. You can then use drag-and-drop action to arrange
the object files in a graphical memory mapping representation. When you
are satisfied with the memory layout, you can generate the executable file
( ) via VisualDSP++ project options.

memory map and the object mappings. The memory map displays in the
Expert Linker window.
Use this display to modify the memory map or the object mappings.
When the project is about to be built, Expert Linker saves the changes to
the . file.
LDF
Expert Linker is able to show graphically how much space is allocated for
program heap and stack. After you load and run the program, Expert
Linker can show how much of the heap and stack has been used. You can
interactively reduce the amount of space allocated to heap or stack if they
are using too much memory. Freeing up memory enables you to store
other things like DSP code or data.
