Hardware Implementation of Floating Point Matrix Inversion Modules on FPGAs

Abstract

Matrices are employed for diversified applications such as image processing, control systems, video processing, radar signal processing, compressive sensing and many more. Finding inverse of a floating point large scale matrix is considered to be computationally intensive and their hardware implementation is still a research topic. FPGA implementation of four different floating-point matrix inversion algorithms using a novel combination of high level language programming and model based design is proposed in this paper. The proposed designs can compute inverse of a floating point matrix up to a matrix size of 25×25 and can be easily scaled to large size matrices. The performance evaluation of proposed matrix inversion modules are carried out by their hardware implementation on a Zynq 7000 FPGA based ZED board and the results are reported.
