Digital Circuits and Flip-Flops

• Big-endian refers to a system where the most significant byte of a multi-byte value is stored at the lowest memory address. This contrasts with little-endian, where the least significant byte is stored at the lowest memory address.

Connecting Negative Q to Clock

• Connecting the negative Q output of a flip-flop to the clock input creates a specific circuit behavior.
• This configuration effectively locks the flip-flop's output, preventing it from changing state independently of the clock signal.
• This connection is often used in specialized circuits or to create self-resetting counters.
• Negative Q output of the flip-flop toggles at the falling edge of the input clock. Therefore, if this negative Q output is fed back to the flip-flop clock input, the flip-flop will change state at the falling edge of its output signal.

Logisim MOD 6 Counter

• A MOD 6 counter is a digital circuit that counts from 0 to 5 and then resets back to 0.
• This type of counter is essential in a variety of applications, including digital clocks, timers, and sequential logic systems.
• Logisim is a digital logic design tool allowing for simulation and visualization of circuits.
• Designing a MOD 6 counter in Logisim typically necessitates use of a counter with inputs and outputs that are configurable and monitored according to the program logic conditions.
• The design will often involve flip-flops connected in a specific manner to increment and reset the counter at the desired count value (in this case, 6).
• In Logisim, you'd wire a 3-bit counter to count up. The output of the counter is wired to a decoder/comparator to detect when the count reaches 6.
• When the count reaches 6 (in binary 110), the comparator output triggers a reset signal to the counter, bringing it back to zero (binary 000).
• The output of the counter can be displayed using a 7-segment display block in Logisim to observe the counting sequence.
• Understanding the behavior of each input and output component in Logisim is crucial for developing and testing the MOD 6 counter.
