Abstract

Exclusion Circuit Identifying First Unrecoverable Event in a Series of Unrecoverable Events Disclosed is a device that identifies the first occurrence in a series of unrecoverable events. In the system that is being developing error detection is critical. Some of the errors that are detected can be recovered from. Some recoverable errors are; correctable memory ECC and PCI device errors. Other errors are unrecoverable; for example: parity error, some bus protocol errors, bus time-out errors and internal chip errors. If these unrecoverable errors where to propagate throughout the system, corruption of the customers data would occur. Therefore the system will halted immediately upon the system detecting these unrecoverable errors. An Exclusion Circuit is needed to identify the first unrecoverable event. Ports
