A very fast Jacobi-like algorithm for the parallel solution of symmetric eigenvalue problems is proposed. It becomes possible by not focusing on the realization of the Jacobi rotation with a CORDIC processor, but by applying approximate rotations and adjusting them to single steps of the CORDIC i Igorithm, Le., only one angle of the CORDIC angle sequence defines the Jacobi rotation in each step...

Direct digital synthesis (DDS) is a method to generate waveforms directly in the digital domain. In this method,the target waveforms are the sine and cosine ones. The Co-ordinate Rotational Digital Computer (CORDIC) algorithm configured in Rotation Mode (RM) can behave as a quadrature phase-to-amplitude converter that directly generates sine and cosine waveforms. The main advantage of using COR...
