#1080 - 32bit maths on 8052
Hi,

I have just had to write a routine to evalutate the following function:

(8000000H)/ 2^(14-ctr)/16bit number. Its a 32 bit numerator divided by two 16 bit numbers. Then I add another 16bit number.

I have code that will do it, but the 32 bit divide is VERY time consuming, and the routine takes nearly 1.9 mSec to execute on a 24Meg 80C320.

Can anyone suggest some optimisation ? The 2^(14-ctr) I have done by walking a bit through a Word, the 32bit divide is a hacked up INTEL example.

I can post the code if anyone can help.

Steve
