Assignment NO 2 Exercise N1 Show the block diagram of the hardware that implements the following register transfer statement: yT: R2R1, R1+R2 Exercise N2 . Represent the following conditional control statement by two register transfer statements with control functions. If (P = 1) then (R1+R2) else if (Q = 1) then (R1R3) Exercise N3 Draw the block diagram for the hardware that implements the following statements: x+yz : AR AR + BR Where AR and BR are two n-bit registers and x, y, and z are control variables. Include the logic gates for the control function. (Remember that the symbol + an OR operation in a control or Boolean function but that it represents an arithmetic plus in a micro operation.) Exercise N4 What has to be done to the bus system in the following figure to be able to transfer information from any register to any other register? Specifically, show the connections that must be included to provide a path from the outputs of register C to the inputs of register A. MIS MIN MUK 1 33 Exercise NS A digital computer has a common bus system for 16 registers of 32 bits each. The bus is constructed with multiplexers. a. How many selection inputs are there in each multiplexer? b. What size of multiplexers are needed? c. How many multiplexers are there in the bus? Exercise N6 The following transfer statements specify a memory. Explain the memory operation in each case a. R2 b. MARI c. RS MARI R3 MIRSI Exercise N7 Show the hardware that implements the following statement. Include the logic gates for the control function and a block diagram for the binary counter with a count enable input. xyTo + T + y'T : AR AR +1
