writing nxn matrix inversion by verilog code

sffong2 · Oct 30, 2012

Hi,
I have a project on writing a n*n matrix inversion by using verilog code. I hope can doing this by using QR decomposition. Can anyone give me some clue on:
1) how can making the code is suitable for n*n matrix by just changing the parameter ?
2) a module that can do floating point division.

Hi,

a module that can do floating point division.

Why do you need floating point. It is difficult to deal with it. If possible to any extent you should use fix point.
but I think that in Xilinx core generator you can make floating point division module (if you are using xilinx FPGA).

About point 1 can you explain a little, you need to store your data in some sort of memory before inverting your matrix. I think it is some sort of image matrix, right?
Can you give some detail about point 1

Bests,
Shan

Hi,
I am using Altera quartus ii version 9.1 to doing this project. The point 1 that I mentioned is ,for example ,determinant for a 2x2 matrix, det= (a11*a22 - a12*a21 )
however, in matrix 3x3 det= a11 (a22*a33-a23*a32) - a12 (a21*a33-a23*a31) + a13 (a21*a32-a22*a31). the number of input and function are different, how can I doing this determnant by just changing the parameter n? Because I am doing n*n matrix, mean the module that I doing can used for any matrix size by just changing the parameter,n.
