><P
>The MN10300 simulator is an architectural simulator for the
Matsushita MN10300 that implements all features of the microprocessor
 necessary to run eCos. The current implementation provides accurate
simulation of the instruction set, interrupt controller, timers,
and  serial I/O.</P
><P
>In this release, you can run the same eCos binaries in the
simulator that can run on target hardware, if built for ROM start-up,
with the  exception of those that use the watchdog timer.</P
><P
>However, note that AM33 devices required to run eCos are not
simulated; therefore you cannot run eCos binaries built for the
AM33 under the simulator. For the AM33, the simulator is effectively
an instruction-set only simulator.</P
><P
>To simplify connection to the simulator, you are advised to
create a GDB macro by putting the following code in your personal
GDB start-up file (gdb.ini on Windows and .gdbinit on UNIX).</P
