Playback apparatus and method of controlling a playback apparatus

Each of memory bridges and I/O bridges, cross-linked to one another, is provided with an interface circuit section which performs data transmission and reception according to an PCI-Express interface. Each interface circuit section has a communication error processing section. When an error occurs in data received from the I/O bridge, the communication error processing section of the memory bridge cancels the received data and sends a communication error signal to the memory bridge. When receiving the communication error signal, the memory bridge stops receiving the data. Then, the communication error processing section of the memory bridge requests the I/O bridge to resend data.

In two systems that constitute a fault tolerant system, a router assigns, to an access packet transmitted from a CPU to an IO device, tag information including ID codes of access source and destination and information indicating whether the access packet is synchronous access. An access comparison section has buffers and that retain the packets from the CPU on a system basis, a tag check section that determines whether each packet is synchronous packet access based on the tag information assigned to the packets retained in the buffers, and a comparison section that outputs the packet from one system to an IO IF and discards the packet from other system in the case where the packet is synchronous access.

The CPU subsystem operates at the same timing with a CPU subsystem of other system in lock-step. The FT controller manages a plurality of system operations, according to which both systems perform error processing, duplication processing, and resynchronization processing for fault tolerant, by associating a plurality of states corresponding to the system operations with predetermined event signals. According to these event signals, the FT controller selects the system operations while changing the states for every system and allows the CPU subsystem to perform the selected system operation.
