BUS SYSTEM INCLUDING BRIDGE CIRCUIT FOR CONNECTING INTERLOCK BUS AND SPLIT BUS

摘要

A bus system is configured by connecting an unretriable interlock bus and a split bus through first and second bridge circuits and respectively connecting first and second channels of the split bus and the interlock bus through the first and second bridge circuits. An access from the split bus side to the interlock bus side is processed by the first bridge circuit and an access from the interlock bus side to the split bus side is processed by the second bridge circuit, whereby a deadlock during a bus conflict is avoided.

主权项

1. A bus system having bridge circuits for connecting a split bus and an interlock bus, the bridge circuits being a first bridge circuit and a second bridge circuit, wherein
the first bridge circuit connects the interlock bus and a first channel of the split bus, the second bridge circuit connects the interlock bus and a second channel of the split bus, an access from the split bus side to the interlock bus side is processed by the first bridge circuit through the first channel, and an access from the interlock bus side to the split bus side is processed by the second bridge circuit through the second channel.
