What is the purpose of Byte Enable lines in the PCI bus? The PCI bus uses IRDY# and TRDY# signals to control data flow. Then why does it require the FRAME# signal? Describe the PCI bus arbitration mechanism. We have stated that using a PCI-to-PCI bridge improves system performance. We have used the Intel 21152 chip to illustrate the specifics of such a bridge. Discuss why using the 21152 bridge improves performance.
