why FSM so big

Dear

I implemented 12-state controller and the operations are basically

ld 32bit data -> ld another 32bit data -> compare -> store into memory

The operation above is repeated 1024 times.....

Then I synthesized in FPGA tool.

Problem is that the area is too big (more than 10% of Vertex2pro),
though 'area' optimiation option was used.

When I do the same thing with 128 times of ld/ld/cmp/store, the area
was 3%.

I am wondering why this happens....

and I hope the area of FSM will be constant, regarless of the number of
ld/st...

If someone has this experience or idea, let me know....Thankyou
 
Hi

Yes, it was 'counter' problem...when I removed it, the area is more or
less same...
Thankyou all for good comments
