Abstract: In approaches for correction of errors introduced in an interconnect circuit, an ECC proxy circuit is coupled between a first interconnect and the second interconnect, and generates for each of the write transactions from a bus master circuit, a first ECC from and associated with data of the write transaction, and transmits the write transaction and associated first ECC on the second interconnect. The ECC proxy circuit also supplements each of the read transactions from the bus master circuit with a reference to a second ECC associated with data referenced by the read transaction. The ECC proxy circuit transmits the read transaction that references the second ECC on the second interconnect. At least one random access memory (RAM) is coupled to the ECC proxy circuit through the second interconnect. The RAM stores data of each write transaction and the first ECC.

Abstract: An integrated circuit can include a processor system configured to execute program code. The processor system can be hard-wired and include a processor hardware resource. The IC also can include a programmable circuitry configurable to implement different physical circuits. The programmable circuitry can be coupled to the processor system. The programmable circuitry can be configurable to share usage of the processor hardware resource of the processor system. The processor system further can control aspects of the programmable circuitry such as power on and/or off and also configuration of the programmable circuitry to implement one or more different physical circuits therein.
