With a total of 4 patents to his name, Nakazuru continues to push the boundaries of innovation in his field.
Latest Patents
One of Nakazuru's latest patents is an arithmetic method and function arithmetic circuit designed for fast Fourier transforms. This invention involves a cyclic equation setting unit that transforms and sets a Taylor series equation for calculating a sine function into a single cyclic equation. This equation is common to the terms of the Taylor series and incorporates a new known number Q, defined by multiplying a known number Q and the square of a variable X. The result is shifted by a shift number S and a constant K is added. An adjustment unit prepares the shift number S to ensure that within a variation range of the variable X, the maximum value is 1, with the constant K not exceeding 1. The cyclic equation executing unit inputs angle information and executes the cyclic equation in sequence to derive the sine function.
Another notable patent is a lookup table and data acquisition method. In this invention, input data is divided into multiple blocks, each corresponding to an address in the lookup table. The blocks are further divided into sections based on output data changes, with position information indicating section boundaries. This method allows for a decrease in the memory capacity required for the lookup table.
