Agee Ozeki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Digital signal processor particularly suited for decoding digital audio
    Publication number: 20020053015
    Abstract: A digital signal processor particularly adapted for decoding digital audio. The barrel shifter of the processor includes logical circuitry, so that operations involving a combination of a logical operation and a shift, can be performed in a single pass through the combined barrel shifter/logical unit, rather than requiring separate passes through the barrel shifter and ALU, which would require more instruction cycles. The address generator of the processor, includes circuitry which concatenates the most significant bits of a base address of a table to the least significant bits of an index, to thereby rapidly generate addresses of indexed locations in a table.
