Solution
Every MIPS instruction can be implemented in at most 5 clock cycles.
Here's a step-by-step breakdown:
-
Instruction Fetch: The instruction is fetched from memory in the first clock cycle.
-
Instruction Decode/Register Fetch: The instruction is decoded and registers are fetched in the second clock cycle.
-
Execution/Effective Address Calculation: The actual execution of the instruction or the effective address calculation (in case of memory instructions) happens in the third clock cycle.
-
Memory Access: If the instruction involves memory access (like load or store), it is done in the fourth clock cycle.
-
Write-back: The results are written back to the register in the fifth clock cycle.
So, in the worst case scenario (like a load or store instruction), a MIPS instruction can take up to 5 clock cycles to complete.

<§2.11> Write the MIPS assembly code to implement the following Ccode:lock(lk);shvar=max(shvar,x);unlock(lk);Assume that the address of the lk variable is in $a0, the address of the shvarvariable is in $a1, and the value of variable x is in $a2. Your critical section shouldnot contain any function calls. Use ll/sc instructions to implement the lock()operation, and the unlock() operation is simply an ordinary store instruction.
