It might, in fact, be interesting to see what limitations/enhancements the
hardware features of the two processor types would impose. Interleaved
display memory would effect both processors' ability to use memory, etc.
I'd say it will difficult enough to come up with a problems suitable for a
valid exercise without such difficulties.

Good point.

Nice, but already to high level.
The task should be abstract enough to run within a simple
system, lets say a SBC system with CPU, some MEM and some
of the usual I/O&Controll stuff (Ports, Serial, Timer).
Basicly there are two types of possible challanges:
a) implements some kind of standard code in a most speedy way, or
b) build some small, but sophisticated "real world" application.
Challenge a) would meet the basic idea we had in our discusion:
define at what ratio two processors are equivalent when executing
a real task, while b) should be sophisticated enough to give a
'boh ey' (sound of exeptional admire) effect.
In terms of a sportive competition a) would be a compulsatory
exercise, while b) is more a voluntary (free style) exercise.
As I stated before, for our theme a) would be more aprobiate.
As actual tasks I would suggest
for a): a 'simple' sorting challenge
given is
- Input media
- Input structure
- input data (same data or all participants, randomly generated)
- Type of sort algo to use (what about just a bubble ? :)
- Output structur
- Output media
the score schould be made up from
Execution time (mainly for the sort, but also for I/O)
Programm length (again most points to be given on the sort itself)
Style (readability, portability, maintainability)
for b) a thing like a small multi tasking OS could be used,
maybe for a controlling application (heating or traffic -
or what about a model railroad setup ?) or other purposes ?
(This could be chalenging, since these kind of tasks are
maybe a bit tough for our little helpers :)
So, you're opinion ?
BRING IT ON, MO FO!
Don't rub the lamp if you don't want the genie to come out.
MO FO ? I fear, I'll have to rub the lamp.
