We are executing the following code segment using Tomasulo algorithm: DIV F6, F4, F2 ADD F10, F8, F6 SUB F6, F4, F0 MUL F12, F2, F6 ST F10, 0(R1) ADD F14, F6, F2 Assume that register Fi initially contains value i and register R1 contains 1000. All the instructions have been issued. The SUB has completed the write result stage. The DIV and the second ADD are currently executing on the functional units. The functional units are not pipelined. Show the contents of reservation stations.
