3.3.2 Programming Example Confidence Test
The XP-15 confidence test is located on the XP-15 software CDROM in the examples/cfft directory, and a
listing of the source code can be found in Appendix A. This simple application creates a signal containing a
single impulse, transfers the signal from host memory to XP-15 local memory, performs a one million point
complex FFT on the signal in the XP-15, reads the results back to host memory, and checks the results.
Copy the contents of the examples/cfft/ directory from the CDROM to a suitable local directory. For
instructions on reading the CDROM, please refer to the Installing the XP-15 Software section for the
relevant computer and operating system earlier in this document.
% cp $CDROM/sources/examples/cfft/* .
This will copy two files from the CDROM: cfft.c and Makefile. The make utility can be used to build the
program. The make file assumes that the XP-15 software has been installed in the $TMS directory as
described in the software installation section above. If this is not so, then the make file will have to be
modified to reflect the new software location.
% make
gcc -I$TMS/include -o cfft cfft.c -L$TMS/lib –lvp -lsam
