when emulating, because the decoding is in
the target system. In this particular case it
would be necessary to move the code from
0E000 to 00000 before emulating.
Benefits of memory emulation .
1. It is universal. You can use it with any
microprocessor.
2. The equipment costs less than a
Microprocessor Develoment System.
The only other piece of kit you need is
a computer and a cross-assembler.
3. The target system behaves like the
"real thing".
4. The software runs at full-speed.
5. Memory contents can be inspected,
edited and the program started again
very quickly.
6. It is very cheap and effective with
single-chip microcontrollers which
have a piggy-back version. You plug it
straight into the back of the
microprocessor.
7. It is good for making modifications to
existing systems, such as changing
messages and odd values, especially
where some trial and error is involved.
The "tweak values and try it again"
process works very well.
8. When successful the program can be
transferred to an EPROM immediately.
How Memory Emulation works
The method used is to assemble the program
on a computer and download in one of the
standard file-formats into the emulator. The
