To resolve the clash over the access of the system BUS we use ______
Explanation: The BUS arbitrator is used to allow a device to access the BUS based on certain parameters.
The device which is allowed to initiate data transfers on the BUS at any time is called _____
Explanation: The device which is currently accessing the BUS is called as the BUS master.
______ BUS arbitration appproach uses the involvement of the processor
Explanation: In this approach the processor takes into account the various parameters and assigns the BUS to that device.
The circuit used for the request line is a _________
The Centralised BUS arbitration is similar to ______ interrupt circuit
When the processor recieves the request from a device, it responds by sending _____
Explanation: The Grant signal is passed from one device till the other until the device that has requested is found.
In Centralised Arbitration ______ is/are is the BUS master
Explanation: The BUS master is the one that decides which will get the BUS.
Once the BUS is granted to a device ___________
Explanation: The BUS busy activated indicates that the BUS is already allocated to a device and is being used.
The BUS busy line is made of ________
After the device completes its operation _____ assumes the control of the BUS.
Explanation: After the device completes the operation it releases the BUS and the processor takes over it.
The BUS busy line is used
Distributed arbitration makes use of ______
Explanation: The device uses a 4bit ID number and based on this the BUS is allocated.
In Distributed arbitration, the device requesting the BUS ______
How is a device selected in Distributed arbitration ?
Explanation: The OR output of all the 4 lines is obtained and the device with the larger value is assigned the BUS.
If two devices A and B contesting for the BUS have ID’s 5 and 6 respectively, which device gets the BUS based on the Distributed arbitration
Explanation: The device Id’s of both the devices are passed on the lines and since the value of B is greater after the Or operation it gets the BUS.
