matrix inverse in vhdl

[ahmedomar_2000]

first ,thanks a lot for all who reply me. aruipksni, thank you for the program , i didn't try it yet, but i will . just i want to ask you , which method used in this program ,is it a gaussian elimination ? in fact i have to do the matrix inverse in many ways using VHDL , and then compare between them( execution time ,area ,number of resources ) ,this is a part from my project . i wrote a program before a short time and i used QR decomposition which based on gram shmidt algorithm, but this method requires a lot of operations like additions, subtraction ,division , and square root ,i used the core generator for calculating the division and square root ,but that causes a lot of delay for calculation, so the frequency was very bad , i thought to use the lookup tables for calculation instead of core generator ,but i don't have idea about using the lookup table also i use a 12 bit representation for the matrix elements (fixed point), and i think that will take a lot of area ,i am stuck here ,i searched every where in the net but can't find any vhdl code for calculating the matrix inverse ,and iam also a beginner in vhdl , finally i knew about this web site , so i hope to find the help from you .thanks

I suggest getting reading on digital design as a first step. Without understanding the basics, you wont have a chance trying to understand how to convert and algorithm to use on an FPGA.
