Latest Patents
One of his latest patents is titled "Method and apparatus for changing execution code for a microcontroller on an FPGA interface device." This invention discloses a method for selectively overlaying portions of default firmware code for a microcontroller within an FPGA interface device. The device includes a microcontroller, an on-board FPGA, and a memory with first and second pages. Upon initial power-up, the default firmware code is loaded into the first memory page. The microcontroller then executes instructions from a host system using this code. When updates or modifications are needed, an overlay code is stored in the second memory page, allowing for efficient firmware updates without requiring extensive hardware changes.
Another significant patent is "Embedding firmware for a microprocessor with configuration data for a field programmable gate array." This invention describes an FPGA interface device that includes a microcontroller and an on-board FPGA. The configuration design and firmware code are stored in a serial memory. Upon power-up, the FPGA reads the configuration design and configures itself accordingly. This innovation allows for the elimination of dedicated parallel memory previously used for firmware storage, thus conserving valuable printed circuit board area.
