Honored ContributorHello,
I used C2H to optimize SQR function : This function compute SQRT of 16 bits unsigned integer number. results is on 8 bits. unsigned short sqr(unsigned short Xio){ register unsigned short V= 1<<14; register unsigned short Z=0; register short i; register int temp; register unsigned short X=Xio; for(i=7;i>=0;i--){ Z=Z+V; temp=((X-Z)>=0); X=X-(temp ? Z : 0); Z=Z+(temp ? V : -V); Z=Z/2; V=V/4; }//Fin pour return Z; } After adding sqr function to C2H and configurer in release mode, here is result of make : make -s all includes Compiling board_diag.c...
