The linker is a software program that combines separate object files produced
by the assembler into a single object file. The linker allows the user to create
separate code modules for different sections of code. It also allows the user to
create a library of functions which may be used in a number of different pro-
grams.
Object File - Same as above but each object file contains only a section/module
of the entire program.
Load Map - Specifies how memory is allocated. A typical load map might con-
tain the following sections:
Translates programs written in high-level languages such as C into equiva-
lent assembly language programs. The high-level language is usually a mod-
ified high-level language which allows a combination of the standard high-
level language instructions and assembly language instructions. A compiler
increases ease of programming but decreases code efficiency.
High-level language Source File - A file containing microcontroller program
written in a modified high-level language.
Assembly Out File - A file containing assembly language source code pro-
duced from the high-level language source file.
Range Definitions: Shows memory ranges with assigned names
Memory Order Map: Shows starting and ending ranges of each
contiguous block of memory
Memory Type Map: Shows how address space is allocated to different
types of memory
Total Memory Map: Shows allocation of all RAM and ROM/EPROM
combined
Section Table: Shows starting and ending address of each linked
module
Symbol Table: Same as section table
Cross-Reference Table: Similar to a symbol table, it lists all symbols
and tables with their associated values. In addition, it lists all the
locations where the symbol and tables are being used.
