For this part of Lab 7 you will design the sign extender module for your ARMv8 processor in Verilog. As an example, below is a simple 16 to 32-bit sign extender module: module SignExtender(BusImm, Imm16, Ctrl); output [31:0] BusImm; input [15:0] Imm16; input Ctrl; wire extBit; assign #1 extBit = (Ctrl ? 1'b0 : Imm16[15]); assign BusImm = {{16{extBit}}, Imm16}; endmodule Rewrite this module to meet the needs of your ARMv8 processor. In particular, the sign extender should output a 64-bit BusImm, and it's input should be the 32-bit instruction. Depending on the instruction type (B, CB or D), it should extend the right set of bits in the instruction up to a full 64-bits. Save this module in a file called SignExtender. v.
