Design a data processor, which keeps counting under given conditions. You will use an Algorithmic State Machine (ASM) chart, which will define its digital hardware algorithm. Design a digital system with two flip-flops, E and F, and one 4-bit binary counter, A. The individual flip-flops in A are denoted by A4, A3, A2, and A1, with A4 holding the MSB of the count. A start signal S initiates the system operation by clearing the counter A and flip-flop F. The...

The task is to design a two-bit controlled counter which has two
counting bits (Q2, Q1), has one control input C1, and also two
extra outputs, one indicating overflow, the other underflow.
When C1=0 the counter counts up by 2s; i.e. 0 becomes 2, 1
becomes 3. In this mode the values 2 and 3 go to the overflow
state. When the control input C1=1, the counter counts down by 2s,
i.e. 3 becomes 1, and 2 becomes 0, and...
