Flip-Flops. Last time, we saw how latches can be used as memory in a circuit.. Latches introduce new problems:. We need to know when to enable a latch.. We also need to quickly disable a latch.. In other words, it. Slice and I/O Resources. Objectives. After completing this module, you will be able to:. Describe the CLB and slice resources available in Spartan-6 FPGAs. Describe flip-flop functionality. Anticipate building proper HDL code for Spartan-6 FPGAs. Slice and I/O Resources. Objectives. After completing this module, you will be able to:. Describe the CLB and slice resources available in Virtex-6 FPGAs. Describe flip-flop functionality. Anticipate building proper HDL code for Virtex-6 FPGAs. © 2014 Project Lead The Way, Inc.. Digital Electronics. Flip-Flops & Latches. 2. This presentation will. Review sequential logic and the flip-flop.. Introduce the D flip-flop and provide an excitation table and a sample timing analysis.. Digital Computer Logic. Latches. S-R Latch. Gated S-R Latch. D Latch. RQ2011. 2. A . latch. is a temporary storage device that has two stable states (bistable). It is a basic form of memory. . The S-R (Set-Reset) latch is the most basic type. It can be constructed from NOR gates or NAND gates. With NOR gates, the latch responds to active-HIGH inputs; with NAND gates, it responds to active-LOW inputs.. © 2014 Project Lead The Way, Inc.. Digital Electronics. Flip-Flops & Latches. 2. This presentation will. Review sequential logic and the flip-flop..

A . flip-flop is a bi-stable device: a circuit having 2 stable conditions (0 or 1. ). A flip-flop circuit has two outputs and the outputs of the flip-flop always complement each other, . Read . Kleitz. , Chapter 10.. Homework . #10 and Lab #10 due . next week.. Quiz . next week.. Combinational Logic versus Sequential Logic. A . combinational logic circuit. is a circuit whose output depends only on the circuit’s present inputs. (“Has no memory of the past.”). Chapter 5. Sequential Circuits. Combinational circuits storage (store binary information). Binary information stored defines the state of the sequential circuit. External input present state determine the binary value of outputs and change state in storage elements. Drysdale. Objectives of Lecture. The objectives of this lecture are: . to discuss the difference between . combinational . and. . sequential . logic as well as the difference between . asynchronous. Digital Electronics.
