Parity error detection and recovery

Parity error detection and recovery

In a computer system having a CPU and several buses which includes a system bus and an I/O bus, parity error can occur when data is being written between the I/O bus and the system bus. This invention provides a technique for detecting whether a parity error has occurred on data being written betwee...

Zusammenfassung:In a computer system having a CPU and several buses which includes a system bus and an I/O bus, parity error can occur when data is being written between the I/O bus and the system bus. This invention provides a technique for detecting whether a parity error has occurred on data being written between the system bus and the I/O bus. If a parity error is detected, the address at which such error occurred is stored and then sent on to the system bus to the CPU.
