jpeg_top.py was started from jpeg2000.py this now reads the file sim.dat
and computes 8 fwd even and 8 fwd odd.
The with the transistion from even to odd.
EVEN_SA 3 clocks to read the ram.  Only 2 clocks to read the ram in the ODD_SA state
ODD_SA 3 clocks to read the ram.  Only 2 clocks to read the ram in the EVEN_SA state

The problem with not writing to first
location of ram may resolved when start using sdram instead.
