Now this is what I call an analysis... Thanks.

It turns out that since we are using the xdata reentrant calling convention, in most cases the cost of stacking and unstacking the second data pointer, quickly washes out the advantages gained by the use of the second data pointer. Makes sense. Much like the interrupts entry/exit, mentioned by Andy above. My bet with myself would have been excessive interrupt usage if it would be just the slowdown, not the code bloat. JW |
