Question (4)-Register Transfer-[25 Points] (a) (10 Points) Show the block diagram of the hardware that implements the following register transfer statement: YT₂: R2 <- R1, R1 < R2 (b) (15 points) Consider the following register transfer statements for two 4-bits registers R1 and R2. XT: R1 R1 + R2 x'T: R1 R2 Every time that variable T-1, either the content of R2 is added to the content of R1 if x=1, or the content of R2 is transferred to R1 if x=0. Draw a diagram showing the hardware implementation of the two statements. Use block diagrams for the two 4-bit registers, a 4-bit adder, and a quadruple 2-to-1 Wine multiplexer that selects the inputs to R1. In the diagram, show how the control variables x and T elect the inputs of the multiplexer and the load input of register R1.
