The assembly language code below is run on the micro$-$architecture diagram in the

exam handout. The content of data memory is also shown. For the assembly language

command highlighted with a $"$$$",$ determine the following information:

The register file A$1,$ A$2,$ A$3,$ RD$1,$ RD$2,$ RD$2$U and WD$3$ bus values $($in hex number format$).$

The data memory A$,$ WD and RD bus values $($in hex number format$).$

The values of Branch, MemOp, LdIm, RegWE, ALUCtl and MemWE $($in binary numeber format$).$

Notes:

Once a new command is loaded from instruction memory on a rising clock edge, it

takes a full clock cycle for all bus and control line values to stabilize to their final

values. Your answer should reflect bus and memory values just before the next rising

clock edge. Therefore, if the command with the $"*"$ writes to data memory, you can

assume that the write has not yet occured.

You can assume that all registers in the register file have been set to zero before the

code shown in the question is run.
