Floating- to fixed-point MATLAB algorithm conversion for FPGAs

In a recent survey conducted by AccelChip Inc. (recently acquired by Xilinx), 53% of the respondents identified floating- to fixed-point conversion as the most difficult aspect of implementing an ...

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 ...

Fixed point iteration for max-min sir balancing with general interference functions

Abstract: This paper studies the convergence of a fixed point iteration algorithm for the problem of max-min signal-to-interference ratio (SIR) balancing. Differently from the existing work on the ...

Allow CSV output per fixed point iteration

It is sometimes useful to output quantities after each fixed point iteration, for example, for testing or monitoring fixed point progress. Currently, there is only one execution point for Outputs ...
