After studying the content of these projects, you will be able to:

• Find example of commercial counters and registers in classic technologies, CMOS, LS-TTL, etc.

• Explain the meaning and use of control signals such CE, LD, TC, Q, Din, etc.

• Design synchronous canonical standard counters using plan C1 FSM methodologies in a single file:

• Plan X: (small counters) as a typical enumerated FSM in P6.

• Plan Y: (large counters) encoding states in n-bit radix-2 numbers and using STD_LOGIC_VECTOR signals and arithmetic libraries.

• Design n-bit synchronous counters using:

• Plan C2: components (building blocks) and signals as in Chapter 1.

• Truncate counters using plan C2 to adjust standard circuits to any modulo.

• Expand counters to reach any size.

• Design counters for the common codes: radix-2, BCD, Gray, Johnson, one-hot, etc.

• Design n-bit expandable data registers using plan Y (single file) and plan C2 (multiple components).

• Design n-bit expandable shift registers using plan Y and plan C2.

• Design applications of sequential systems using registers and counters as building blocks.
