Draw the abstract figure of a microprocessor which executes only add, ld$,$ sd instructions in RISC$-$V ISA. The microprocessor should implement following steps.

$$ Take the next instruction from instruction memory by using the address of the instruction

$$ Calculate the address of the next instruction $($Note that there is no branch operation$)$

$$ Take the source operands from the register file or from the instruction

$$ Make the calculation in ALU

$$ Access memory for loading$/$storing data with the correct information

$$ Update register file with the result
