4.1.10 Error Aggregator

The error aggregator is an interface module between certain peripherals that generate specific errors including the C29, RTDMA, Memory controllers, Peripheral bridges, Read Interfaces and ESM. Main purpose of the Error Aggregator is to accumulate various errors from various sources and provide aggregated error output to ESM module. The module also logs the error status, error address and error type information while segregating high priority errors and low priority errors for ESM to generate appropriate action to alert CPU.
