专利汇可以提供BRIDGE BETWEEN TWO BUSES专利检索,专利查询,专利分析的服务。并且A peripheral controller interconnect/industry standard architecture (PCI/ISA) bridge (34) is coupled between the PCI and ISA buses (30, 32) in a computer system. A PCI master (42) in the system asserts address and address parity information on the PCI bus (30) to initiate a master-slave transaction over the PCI bus. The bridge includes logic (60) for comparing the address and the address parity information and generating an address parity error signal when there is an address parity error. The bridge also includes a PCI slave (40) that receives the address parity error signal and generates a target-abort signal in response if the PCI slave (40) has already claimed the address by asserting a device select signal. The bridge also includes logic that prevents the target-abort signal from propagating to the PCI bus (30) whenever this logic receives both the address parity error signal and the device select signal. This allows the master to perform a master-abort and prevents the PCI slave on the bridge from performing a target-abort when there is an address parity error.,下面是BRIDGE BETWEEN TWO BUSES专利的具体信息内容。
