If you are looking for performance with the eigen library and the TI compiler you should probably wait for the next TI compiler versions. The extensive use of template libraries like eigen or boost result in very big binary files for me with a lot of warnings like this one:
Warning: static local variables of extern inline function are not resolved to single copy. Not ANSI C++ Compliant.
The execution speed matches my requirements but is probably not highly optimized compared with the TI libraries.
I am looking forward to the next TI compiler versions with enhanced template support.
