It is more complex than the others I have done.Hi Tony, Hi Kees, There is an instruction decoder in the ARC chip along with the registers, timing, access etc. The coding style is similar to other cpu's but more specific to calculator operation, although I guess you could get it to do other tasks. Check out my HP-97 emulator. It should give you an idea of its source code and operation. You can also write your own source code as it has a compiler as well. http://www.teenix.org cheers Tony |
