3) Explain how above identified hazard can be resolved?
4) Resolve the hazard by using hazard-resolving mechanism.
SRC pipelined instructions:
200: ld r7, r6, 65
204: str r8, 43
208: shl r4, 5

Question#02:
Let us suppose, we have an I/O bus that can transfer 2 bytes of data in one bus cycle. If a system designer is going to attach the following two components to the I/O bus:
Graphics card with a transfer rate of 20 Mbytes/sec
Network card with a transfer rate of 40 Mbytes/sec
What will be the implications for the above scenario after adding two components (Graphic and Network card) to I/O bus?
Note: The maximum frequency of the bus is 20 MHz.
