Chapter 5 Digital building blocks


Up to this point, we have examined the design of combinational and sequential circuits using Boolean equations, schematics, and HDLs. This chapter introduces more elaborate combinational and sequential building blocks used in digital systems. These blocks include arithmetic circuits, counters, shift registers, memory arrays, and logic arrays. These building blocks are not only useful in their own right, but they also demonstrate the principles of hierarchy, modularity, and regularity. The building blocks are hierarchically assembled ...
