Hi, We have one application which was developed in c51. By applying all aptimization techniqs provided by compiler, code size is near to 20k. If we change total code to Assembly from C, how much code size can be reduced?. Please provide me ur inputs.... Ramesh
I thought I'd add my 2 cents here. First of all, I can't see any contradiction between what Drew and Erik said. What I mean is that if you write a complex program entirely in C you'll most likely end up with smaller code than if you write it in assembly language. Of course, it is possible to make a mess in both of those scenarios, but let's assume that the programmer does a sound job. I think all the points raised in the discussion are good ones. To sum up, the recipe is to write good C code keeping in mind that some C language constructs translate into tighter code than others for your particular architecture. For example, in one of my projects I was writing simple menu handling code. Simply replacing 2D array indices with pointers instantly saved me more than 1K of code memory. Best of luck, - mike
