Half Adder Module in VHDL and Verilog. For adding together larger numbers a Full-Adder can be used. A single half-adder has two one-bit inputs, a sum output, and a carry-out output. Refer to the truth table below to see how these bits operate. The code creates a half adder. There is also a test bench that stimulates the design and ensures that it behaves correctly.
The next Verilog/ VHDL project is a specially designed for cryptographic applications. The co-processor has standard instructions and dedicated function units specific for security. The co-processor is implemented mainly in VHDL, but the N-bit Adder is designed in Verilog. The Verilog code for the N-bit Adder will be instantiated later in a VHDL design.
In next posts, implementations of major modules in the co-processor will be presented. The complete co-processor design and implementation will be presented after every part of the co-processor is posted. This post presents for N-bit Adder designed for the co-processor. The Verilog code for N-bit Adder is done by using Structural Modeling.
