VHDL MATRIX 8x8 INVERSE

Hi,

I am working on Reed Solomon (255,239) decoder and it involves calculation of the inverse of an 8x8 Matrix.

Can anyone post the VHDL code for the same?

Thank You,

Regards,

Suhas  M.

Re: VHDL MATRIX 8x8 INVERSE

Im guessing from the question that your new to this ,
There are books written on and PHDs won on this subject.

Matrix inversion in logic is not easy,
have a look on line at how to invert matrix

most tend to use division, which if you think about the hardware needed, is not an easy circuit.

Then you have number of bits questions and errors,
division in inherently going to give errors, one answer to this is to use floating point, but that is even bigger than fixed point, and slower / more clock cycles.

Re: VHDL MATRIX 8x8 INVERSE

Yeah like you guessed, i just started working on vhdl a couple of months ago. So i am kinda new to this. 

But like you explained, yeah the math involved is quite complex. Anyway, any other approach to RS 255,239 decoder on VHDL??
