One of the many
enhancements in the
DS80C320 is its
high-speed architecture.
This architecture
provides an immediate
speed increase with no
change to existing
software. The speed
increase was obtained by
redesigning the
processor core. The
original 8052 used 12
oscillator cycles for
each instruction cycle
whereas the DS80C320
does the same work in
only 4 oscillator
cycles. Generally, the
DS80C320 may be dropped
into an existing 8052
design to immediate
increase speed without
any need to modify the
software. The exception
are programs which have
critical timing issues
which count on given
instructions taking a
certain amount of time
to execute. Such
programs will need to be
modified to take into
account the DS80C320s
faster execution speed.
