7. In a normal branch instruction, we provide the number of instructions we need to go to with respect to the current Program Counter. We want to modify this in the datapath. Suppose, instead of providing the number of instructions, we provide it 16-bit address, which when sign extended to 32 bits and then add 8 to it, will provide the exact address to branch to, what modifications will you make in the datapath below to accommodate it.

The instruction “addi” is an I-type instruction that can be executed using the Single-cycle datapath without modification. Answer the following question: (a) Give values of all control signals needed to execute this instruction on the single-cycle data. For example: addi $t2, $S2, 3.
2- Write a program in assembly language for the 8085 microprocessor to receive 10 bytes of data via the SID and store it at the memory address (3000h) using a baud rate of 1200. And two high pulses must be sent before each byte (start bits) and one low pulse after each byte (end bits).
