Abstract
A method for configuring programmable logic in an IC to implement instances of a relocatable circuit includes, for each instance, assigning a respective portion of an address space of a processor to the instance, configuring a respective interface circuit for translating the transactions accessing the respective portion of the address space into a fixed address space of the relocatable circuit, and selecting a respective region within an array of programmable logic and interconnect resources of the IC. The processor accesses the address space with read and write transactions issued on an interface bus. The relocatable circuit is independent of the address space assigned to the instances. Each region is configurable to implement an instance. The programmable logic and interconnect resources are configured to implement the instances and to couple each instance to the interface bus of the processor via the respective interface circuit, using a single copy of configuration data for the relocatable circuit.
