Abstract

An example multi-master system in a system-on-chip (SoC) includes a plurality of master circuits, an error-correcting code (ECC) proxy bridge comprising hardened circuitry in the SoC, a local interconnect configured to couple the plurality of master circuits to the ECC proxy bridge, a memory not having ECC support, and a system interconnect configured to couple the ECC proxy bridge to the memory. The ECC proxy bridge is configured to establish an ECC proxy region in the memory and, for each write transaction from the plurality of master circuits that targets the ECC proxy region, calculate and insert ECC bytes into the respective write transaction.
