Abstract
An error recovery mechanism for an interconnect is disclosed. A data processing system includes a bus connected between a bus master and a bus slave. In response to a parity error occurring on the bus, the bus slave issues a bus parity error response to the bus master via the bus. After waiting for a predetermined number of bus cycles to allow the bus to idle, the bus master then issues a RESTART bus command packet to the bus slave via the bus to clear the parity error. If the RESTART bus command packet is received correctly, the slave bus will remove the parity error response such that normal bus communication may resume.
