i need help with both questions ( 2 and 3 ) please

Problem 2) Draw the intemaLorganization for a CPU with Accumulator 16-bit data and 8-bit address busses. Show the widths of all registers as well as all external and internal buses. Problem 3) Given the following assembly program for the Accumulator architecture in Problem 2: load M[100] add M[101] mult MI102] store M[103] a) b) c) How many bits would each instruction require to be encoded in binary? For every instruction in the above program, provide a possible binary encoding. Calculate the total memory (in bytes) needed to store the program. d) For every instruction in the above program, draw in a flow chart the micro execution steps e) Assuming an execution on a GHz CPU, where every step requires a number of clock cycles (cc) as shown below, calculate the execution time for every instruction, then for the whole program.
