Abstract: Based on the dichotomous coordinate descent (DCD) algorithm,having the next iteration with the power of half step size after a successful iteration guarantees the convergence speed when it solves the problem with the linear equations.It makes it possible to get the ratio of two numbers without multiplication on FPGA.MATLAB simulation is carried out to verify that the DCD algorithm has higher convergence speed in the application．

Key words: DCD algorithm; step size; linear equations; the ratio of two numbers; divider without multiplier
