C.4 Simulator Command Files for Stack Analysis
C.5 Code and Data Size from Map Files
The linker can generate a map file describing the memory map of the application (encoder or decoder). This option
is enabled either in the linker command line using the –M (or –Map <file>) option or from the compiler shell using
the –dm <file> option. The map file provides a great deal of information about both the vocoder code and the
application that runs it, and some effort is required to separate the vocoder information from the application
information. The map file provides size and memory location information for all global variables and functions, as
well as total memory allocated to each object file. The size of local (static) variables and functions are derived from
this information. Example 19 lists fragments from a map file generated for the encoder tester application. The line
numbers on the left are manually inserted for reference.
