-
- I have been asked to jot down a list of advantages and disadvantages
- of using an Intel 386 against a GPS MA31750 (MIL-STD-1750A) processor
- by the end of this week (5th April 1996).
-
- The software will be a real-time design in an embedded system,
- probably developed and cross-compiled using a UNIX box.
-
- I am in the unfortunate position that the company I work for has built
- a MIL-STD-1750A computer for use in space (i.e. using rad-hard parts)
- so it is going to take some pretty good arguments really to persuade
- them to let us use a 386. Having had no experience in using a 386 as
- an embedded target, I'm not sure that the reasons I could come up with
- myself would be persuasive enough so I'd be enormously grateful if
- anyone could help me with the following:
-
- 1) The number and quality of Sun SPARC hosted 386 cross-compilers
- versus MIL-STD-1750A cross-compilers.
-
- 2) The availability of cross-compilers on other hosts.
-
- 3) Any serious problems with the compilers themselves or the customer
-
- support.
-
- 4) Recommendations of particular compilers.
-
- 5) Purchase cost.
-
- 6) People's general opinions on how easy it is to develop a system
- using these particular processors.
-
- I would be particularly interested in any figures anyone has regarding
- productivity (e.g. number of lines of code / day) on these processors,
- particularly with respect to use of Ada.
-
- I would be most grateful for any advice/opinions/vendor contacts that
- you could provide me with.
-
- Please contact me by email as I have posted this to a number of (I
- hope) relevant but complementary groups.
-
- If this message is out of place in your group please forgive me.

- Best Regards
