sdram - write operation takes different cycles for execution for each emu-build

I have a small piece of code which writes data into sdram memory in a
loop. I always reinitialize the CYCLES as zero before this operation
and then right after the write loop, I store the CYCLES value into
memory. If the data buffer which I am accessing is in L1 memory, it
gives the same CYCLE value for every re-build and re-run, but its never
consistent for SDRAM.

Working on EZ-KIT.

My code is something like this, written in ASM :

CYCLES = zero.
WRITE DATA INTO SDRAM IN A LOOP (BUFFER SIZE = LOOP SIZE = 5000).
cycle_count = CYCLES.

The above variable cycle_count gives different valeus for each builds! Start a New Thread
