Study Notes
Writing to a Flip-Flop Register
- A flip-flop register can be written to using a circuit with an AND gate (AND2) and an AND2B1 gate for clearing the register.
- The "write" signal must be high to enable writing to the register.
- The "clear" signal must be low to clear the register.
- A clock signal controls the timing of the write operation.
- The output of the flip-flop is connected to a "data out" signal.
- The circuit uses a FJKC type of flip-flop.
Reading from a Flip-Flop Register
- A flip-flop register can be read from using a circuit with an inverter (INV) and a tristate buffer (OBUFT).
- The tristate buffer is enabled by the "RCI" signal, which must be low for the output to be active.
- The "Din" signal is used to write to the register.
- The circuit uses an "active low" signal, meaning the output is active when the "RCI" signal is low.
- This design allows multiple registers to share the same pathways on a bus.
Key Principles of Synchronous Digital Circuits
- Clock signals are used to control the timing of operations.
- Gates and buffers are used to enable and disable output signals.
- These mechanisms are essential in synchronous digital circuits.
