Possesses Pia two Pia support the duplex host bridge

摘要

PROBLEM TO BE SOLVED: To efficiently process mixed transactions by connecting a 1st secondary bus and a 2nd secondary bus and connecting a bridge to a system bus which generates one logical bus supporting more peripheral devices than a previously set number. ;SOLUTION: A system 10 connects one host processor 12 to the 1st secondary bus 14 like a system bus that supports many peripheral devices which can be used by a multiprocessor system and also connects the other host processor 12 to the 1st secondary bus 14. Then the host bridge 20A is connected to the 1st secondary bus 14 and the 1st secondary bus 14 and 2nd secondary bus 16 are connected to each other. Further, a system memory 15 is connected to the 1st secondary bus 14 and 30 and 40 as other devices are connected to the 2nd secondary bus 16. Consequently, mixed transactions of the host bridge 20A can efficiently be processed.;COPYRIGHT: (C)1998,JPO
