a) (6) Consider the circuit diagram for the hirury cell (BC) below, and the RAM circuit at the bottom of the page Contents of the binary cells are shown below for an initial time. when the memory is disabled (EN) Determine the memory contents and circuit output after the inputs have been changed as follows: • Inputs: EN-1 Read Write-1 Address-11 Input Data - 1001 Matery Contents Is this Read or Write operation Output data- • Inputs: EN-1 Road Write-0 Address-00 Input Data - 1001 Matery Content Initial memory cont b)(4 poi) Draw a circuit diagram for a sequential, bit-serial adder, designed to add two 4-bit members. It is composed of a one-bit full adder, two-4-bit registers A., and one additional register, C, to store carry out. The result should be stored in register A. Time 1, A- c) (5 point) Explain the operation of the adder by answering the following question Assume that isters are filled with the following data: A-0001, 1-0011. Show the state of the legister and the carry out Cat each of the four states of operation. Time, A C-D() Time 2, A- Time 3, A- Is this Read or Write operation? Output data- Time 4, A- C-
