National Semiconductor HPC16083/HPC46003 High Performance mi |
|
|
Hello,
I inherited an embedded computer using the National HPC 46003 processor. I
am obliged to correct some programming problems in the code but I have
little information and no tools. I have only found some high level spec
sheets and app. notes. I'll probably need to hand assemble the changes but I
need sufficient info to build the object code. Does anyone have the User's
Manual, assemblers, etc for this processor that can help?
Thanks,
Bob |

The HPC was a fine micro in its day - I believe it was one of the |
fastest microcontrollers available at the time (15 years ago?). It's a
16-bit accumulator-based CISC cpu, with a reasonable range of addressing
modes. We used to have an emulator for it, but it's unfortunately
broken. It was an impressive system - a main board around 50cm by 50cm,
with a "daughter" board at about 30cm by 50cm. The assembler was, as
far as I can remember, free (or at least very low cost), while the C
compiler from National Semiconductor cost extra. It's been about 10
years since I've written a new program on the HPC, but the last
modification I made to a HPC program was a couple of months ago.
Talk to your National Semiconductor representatives about tools and
documentation. If they can't give you the tools, but can authorize a
free copy, then I can send you a zip of the assembler and linker (and C
compiler, if they authorize that too). That might be easier to deal
with than the originals, which I believe came on 5 1/4" floppies. The
documentation would be harder - I think I only have it in dead tree format.
As long as you don't have to debug anything (which you might avoid, if
you are only modifying a working system), then the HPC is fine to work
with in assembler, or even its (slightly limited and very old fashioned)
C compiler. It's certainly much more programmer friendly than many
8-bit micros.
Good luck!

I agree with David, a fine micro - every micro that National does
seems to dissapear :-(
Still have the tools and documentation - Even have some spare micros
somewhere Im sure..
