This book presents the design of computer arithmetic circuits for four arithmetic operations using three number representations. The circuits are designed using algorithms or traditional design techniques and implemented using Verilog hardware description language (HDL) in the SILOS simulation environment. For each design method, the text illustrates the underling theory, examples of use, organization of the arithmetic function, logic design of the circuit, and Verilog HDL implementation. Verilog projects, including the design and test bench modules, as well as outputs and waveforms obtained from the simulator, illustrate the complete functional operation.
