Implementing matrix inversions in fixed-point hardware

We implement fixed-point matrix inversion on a Virtex-4 FPGA using a synthesizable QR-decomposition MATLAB model and the AccelDSP Synthesis tool. The resulting function occupies 12% of a XC4VSX55 ...

Fixed Point Iteration-based Problem Solution without the Calculation of the Jacobian

Abstract: In technical applications typical problems arise that can be “differentially” treated by the calculation and subsequent inversion of certain Jacobi matrices. However, in many cases, the ...

D. M. Young, “Iterative Solution of Large Linear Systems,” Academic Press, New York, 1971.

ABSTRACT: In this paper, Aitken’s extrapolation normally applied to convergent fixed point iteration is extended to extrapolate the solution of a divergent iteration. In addition, higher order Aitken ...
