Inventor: NAKAMURA YUJI
IPC: G06F13/00
Filed: 2003-01-14
Abstract: <P>PROBLEM TO BE SOLVED: To precisely transmit the parity error of a first bus to a second bus in a bus bridge circuit connected to the first and second buses to perform data transfer between devices.  <P>SOLUTION: A new parity bit is generated from a parity bit generated in a first PCI device 18 and a byte enable signal from a second PCI device 8, and transferred to the second PCI device 8 with the read data from the first PCI device 18. Therefore, even if the byte enable value is differed between the primary and secondary buses, the parity error of the secondary bus can be precisely transmitted to the primary bus. This is realized by a simple additional circuit, and such a function is easily realized at low cost.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
