My suggestion would be that you have reached the point where you should go on
an
adventure and enter the wonderful world of C54xx assembly language
progamming.
Those
valuable guard band bits are waiting there like treasure to be discovered.

I am using a 5416 doing some filtering and would like to have access to
the
40 bit registers from C. I originally wrote my code using long long
datatypes(64 bit on the PC) but I found that when I transfered the code to
CCS 2.0 the long long types are not supported.
Does anybody know if there us a way to use these 40 bit registers (as I need
to use their guard bits) from C. The intrinsics seem to always scale to q31
or saturate.
