Latest Patents
Sen W Chu holds a patent for a "Digital phase to digital sine and cosine amplitude translator." This invention generates sine and cosine outputs from an input angle word. The input angle is decomposed into the most significant bits (MSBs) and the least significant bits (LSBs). The octant number of the angle is identified by the octant identifier bits. Radix-4 multiplier/adder circuits are utilized to improve the efficiency of multiplication and addition computations. An incrementor and a decrementor are employed for sine and cosine MSB computations, respectively, which further conserves computer memory and logic. In a preferred embodiment, the MSBs of the sine and cosine outputs for all octants are generated based on the octant number of the input angle. The LSBs of the outputs are produced through trigonometric approximations and octant selection, resulting in significant savings in computer memory and logic.
