[FONT="]Question No 1[/FONT]
Let us consider an I/O bus that can transfer 6 bytes of data in one bus cycle. presume that a designer is considering to attach the following two components to this bus:
Hard drive with a transfer rate of 80 M bytes/sec
Video card with a transfer rate of 200 M bytes/sec
What will be the implications if both of these components need to work simultaneously?
(The maximum frequency of the bus is 30 MHz)
[FONT="]Question No 2[/FONT]
If a bus requires 15 nsec for bus requests, 10 nsec for arbitration and the average time to complete an operation is 10 nsec after the access to the bus has been granted, is it possible for such a bus to perform 40 million IOPS?
