Latest Patents

One of David's latest patents is for a digital controller for automatic rate detection and tracking of audio interface clocks. This invention provides systems and methods to achieve a digital audio interface that can automatically detect and track digital audio streams. The system includes a digital controller that works in conjunction with an analog phase-locked loop (PLL). This innovation eliminates the need to know or communicate the operating rate of the interface in advance, allowing for asynchronous switching between different audio streams. The digital controller modifies the feedback divide ratio of the PLL to minimize the phase error between the device clock and an arbitrary audio interface clock.

Another significant patent is for a sparse-coded look-up table (LUT). This LUT is organized into multiple rows, each indexed by an index value and storing coefficients for processing digital data. The LUT features repeated sections where coefficients for successive index values form a cycle, with the number of coefficients not being an integer power of 2. This design allows for efficient conversion of a digital count to a gain in dB, optimizing the size of the LUT in terms of circuit area or programming logic.
