Consider Code Sequence Executing Smp System 2 Processors Implemented Snooping Bus System U Q37097521

Consider the code sequence below in executing on an SMP systemwith 2 processors implemented with a snooping bus. The system usesMSI protocol. Assume R2 is initialized to 0x0200 on both processorsin cycle C0. ISA format:

opcode <t> <src1> <src2 Cycle CO: C1: C2: C3: C4: ะก5: Ce: C7: C8: Processor0 Processor 1 nop ld R1, 0(R2) addi R1, 0x72 st R1

Fill in the status of the cache line for the address 0x0200 foreach cycle for both processors. In MSI protocol, a cache line canbe I (Invalid), S (Shared), or M (Modified) state.
