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. Any help would be appreciated.

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. -Jeff |
