        Does anyone have a matrix-inversion program for the dsp56000 (that
works)? I have been working on it for a while and there seems to be a
problem implementing it with fractions, since either the original or the
inverted matrix have coefficients larger than one.
        I know this is not a usual DSP problem - a high-language solution
on a microprocessor is probably easier. But the decision was made by
someone else and I was left to implement it...
        I tried a C program that worked OK on PC but when compiled (by
motorola cc56000 compiler) and run on a Loughborough card it failed
claiming that "the program damaged the user interface".
        I prefer am assembly program but any solution is welcome.

        please email me directly if possible to EESADEE$VMSA.TECHNION.AC.IL
