The PCI follows a set of standards primarily used in _____ PC’s.
Explanation: The PCI BUS has a closer resemblance to IBM architecture.
The ______ is the BUS used in Macintosh PC’s.
Explanation: The NuBUS is an extension of the processor BUS in Macintosh PC’s.
The key feature of the PCI BUS is
Explanation: The PCI BUS was the first to introduce plug and play interface for I/O devices.
PCI stands for _______
Explanation: The PCI BUS is used as an extension for the processor BUS.
The PCI BUS supports _____ address space/s.
Explantion: The PCI BUS is mainly built to provide a wide range of connectivity for devices.
______ address space gives the PCI its plug and play capability.
Explanation: The coniguration address space is used to store the details of the connected device.
_____ provides a seperate physical connection to the memory.
Explanation: The PCI bridge is circuit that acts as a bridge between the BUS and the memory.
When transfering data over the PCI BUS, the master as to hold the address till the completion of transfer to the slave.
Explanation: The address is stored by the slave in a buffer and hence it is not required by the master to hold it.
The master is also called as _____ in PCI terminology.
Explanation: The Master is also called as initiator in PCI terminology as it is the one that initiates a data transfer.
Signals whose names end in ____ are asserted in the low voltage state.
A complete transfer operation over the BUS, involving the address and a burst of data is called _____
The device connected to the BUS are given addresses of ____ bit.
Explanation: Each of the devices connected to the BUS will be allocated an address during the initialisation phase.
The PCI BUS has _____ interrupt request lines.
Explanation: The interrupt request lines are used by the devices connected to raise the interrupts.
_____ signal is sent by the initiator to indicate the duration of the transaction.
Explanation: The FRAME signal is used to indicate the time required by the device.
______ signal is used enable commands.
Explanation: The signal is used to enable a 4 command lines.
IRDY# signal is used for _______
Explanation: The initiator transmits this signal to tell the target that it is ready.
The signal used to indicate that the slave is ready is _____
DEVSEL# signal is used
This is signal is activated by the device after it as recognised the address and commands put on the BUS.
The signal used to initiate device select ________
Explanation: This signal is used to initialisation of device select.
The PCi BUS allowsus to connect _______ I/O devices.
Explanation: The PCI BUS allows only 21 devices to be connected as only the higher order 21 bits of the 32 bit address space is used to specify the device.
