solve the following Computer Architecture and Organisation Problem on (Instruction Set Architecture and designing of processor)? Please show me the step by step solution on how to design. Thank you.

7. Given the ISA of Processor pico CP-SYS 2013 and components, General Purpose Register of 4 x 8 bits. . Memory with 8-bit address and 8-bit data bus Extender will give {0000,[immediate]} and {[immediate],0000} depending on EXT_OP (0 and 1 respectively) Instruction Memory and Data Memory are sperated. You may use unlimited numbers of multiplexor, adder and register 7 Instructions LI $immediate (I-Type), opcode = 1100 PC-PC+1, REG[3]={0000,[immediate]} LUI $Immediate (I-Type), opcode = 1101 PC-PC+1, REG[3]={[immediate],0000} ALU with the following operation (Z=1 when S is 0.) LW $RD, $RS (R-Type), opcode = 1000 ALU_OP DESCRIPTION PC=PC+1, REG[RD]=MEM[REG[RS]] 00 01 10 11 S=A+B S=A S=B S=0 SW $RD, $RS (R-Type), opcode = 1001 PC=PC+1, MEM[REG[RS]]=REG[RD] ADD $RD, $RS (R-Type), opcode = 0010 2 instruction formats (8 bit) Format (#bit) PC-PC+1, REG[RD]=REG[RD]+REG[RS] MOV $RD, $RS (R-Type), opcode = 0011 PC-PC+1, REG[RD]=REG[RS] R-type OP RD RS BZ $RD, $RS (R-Type), opcode = 0111 I-Type OP Immediate IF (REG[RS]==0) PC=PC+REG[RD]+1 ELSE PC=PC+1 Please design the complete Data Path of Processor pico CP-SYS 2013
