Suppose 8 bit registers have following contents X=00001111 Y=10101010 Z= 11011011 W=00110011 What will be the 8 bit values of each register after execution of following sequences of microoperations ? X ← 𝑋 + 𝑌 Z←Z⋀ 𝑊, 𝑌 ← 𝑌 + 1 X←X-Z

 The outputs of four registers, A, B, C, D, H, L are connected through 8:1 line multiplexer to the input of a fifth register, X. Each register is 16 bits long. The required transfers are dictated by four timing variables, T0 through T3 as follows: T0 : X←A T1 : X←B T2 : X←C T3 : X←D The timing variables are mutually exclusive, which means that only one variable is equal to 1 at any given time, while the others are equal to 0. Draw a block diagram showing the hardware implementation of the register transfers. Include the connections necessary from the four timing variables to the selection inputs of the multiplexers and to the load input of register X.

A common bus system which is capable of transferring 2 bits at time with number of registers are 4 each register is of 2 bit? Draw circuit diagram for this and also define how many multiplexers are required and what will be the size of multiplexer with truth table Also explain how to gather data from this bus back into register
