Problem #7 Assume we want to execute the following new instruction on the MIPS single-cycle data path Idr R[rt], constant(PC+4): signExt constant] This instruction uses I-format and performs: R[rt] MIPC+4+ op rs rt constant or address 6 bits 5 bits 5 bits 16 bits Note that rs field is not used by this instruction. The opcode of the ldr instruction is 0010002. Modify the data path and identify the values of the following control signals needed for this instruction and then modify the given control unit (discussed in class) to implement the control signals.
