Patent number: 11314680Abstract: Methods and apparatus for implementing a bus in a resource constrained system. In embodiments, a first FPGA is to a parallel bus and a second FPGA is connected to the first FPGA via a serial interface but not the parallel bus. The first FPGA processes a transaction request, which has a parallel bus protocol format, to the second FPGA by an initiator and converts the transaction request to the second FPGA into a transaction on the serial interface between the first and second FPGAs. The first FPGA responds to the initiator via the parallel bus indicating that the transaction request in the format for the parallel bus to the second FPGA is complete.Type: GrantFiled: October 9, 2020Date of Patent: April 26, 2022Assignee: Raytheon CompanyInventors: Hrishikesh Shinde, Daryl Coleman
