intrinsic function for 32bit multiplication hello, are there intrinsic functions available for the XC164 to use the multiply unit of the ALU? For example for calculations like: 16bit x 16bit = 32bit (MUL-instruction)or 32bit / 16bit = 16bit (DIVL-instruction)? regards! Andreas

Besides, why would you need them when the compiler emits the appropriae instructions well enough? Just compile the following piece of code and see the compiler output: int a, b; long c; void main(void) { c = a * (long)b; b = c / a; } Regards, - mike
