Latest Patents
One of Dowdal's latest patents is titled "External memory data management with data regrouping and channel look ahead." This invention involves a device that manages data for a digital signal processor. The device includes an external random access memory (RAM) configured to store channel-specific data for multiple channels. A microprocessor communicates with the external RAM and efficiently processes packets by determining the corresponding channel and fetching specific data into its internal memory. This innovation enhances the speed of data processing by minimizing wait times at the application layer.
Another significant patent is "Memory optimization packet loss concealment in a voice over packet network." This method aims to reduce memory requirements for a packet loss concealment algorithm during packet loss in pulse code modulated voice signals. The voice playout unit in the receiver shares its nominal delay buffer with a history buffer, which helps in optimizing memory usage. This approach not only reduces the need for additional memory allocation but also retains original voice signal packets prior to packet loss.
