Abstract:
Access is provided to user registers of a user design implemented on an integrated circuit (IC). A memory of the IC is initialized with instructions, and a portion of the programmable logic and interconnect resources of the IC is configured to implement an access interface, multiplexer logic, and the user design. A processor is coupled to the programmable logic and interconnect resources and executes the instructions from the memory. The processor receives from an external user interface, via the access interface, an access command. For a read command, the processor reads a value from an identified user register and transmits the value to the external user interface. For a write command, the processor writes a write value specified by the access command to the specified user register via the multiplexer logic. The processor and the user design are both coupled to write to the user registers via the multiplexer logic.
