Program Code Size and Data Memory Usage

Started by Daniel May 5, 2005
Hi everybody!
I am programming a TI 6713 DSP with the Code Composer Studio V 2.21 in
C and have a question concerning it.

Is there an easy way to see the size of the program code (not the
C-Code, but the compiled code that is transmitted to the DSP) and the
maximum of data memory used?

I want to compare MATLAB-generated Code with my own handwritten code
and see which one is smaller and uses less data memory.

Thank you all

Daniel

It is possible to estimate these things in a number of different ways in TI development environment.I will just reccomend one of the many many methods: This is via the usage of a MAP file. This map file can be generated by enabling this option in project->build options->linker tab->under Map file name type in a name with .map extension (ex:.\Debug\dotproduct.map) Upong building the project based on these configuration you would find a dump of this text file name.map in your project folder. This is a sort of a symbol table+ section length info bundled into one. Basically if you are interested in code/data size,you shd look for the sizes of the following pre-defined sections: text ----> code bss ----> Global/Static Variables stack----> Stack for local variables sysmem----> Memory for malloc fcns (heap) cinit ----> Initial values for global/static vars far ------> Global and statics declared far cio ------> Buffers for stdio functions A Typical MAP file might read something like this(I hope the formatting is alright when you read it in a different resolution...) example.map ----------------------------------------------------------------------

Yes, there should be a .map file in the debug directory that gives all the 
information on memory allocation.  I believe it's generated by default.  If 
it's not there then you can go to Project -> Options and then go to the 
linker tab and specify a file name in the field that shows map file.

Under  you installed directory bin
there is
two command line  tool available.
"sizeti"  (which will give you in one shot how much code, data memory u
are using)
and second one "secti" (will give you usage per section , this is very
similar to map file result but in more readable format)
But if you like do dive in MAP file is the best.
