Design Example 9-18 Latches in Asynchronous Circuits The traditional configuration of asynchronous circuits is using one or more feedback loops No real delay elements It is more convenient to employ the SR latch as a memory element in asynchronous circuits Produce an orderly pattern in the logic diagram with the memory elements clearly visible. To analyze the circuit we break the feedback loop as shown in Figure 222b. Whether to use synchronous or asynchronous resets in a design has almost become a religious issue with strong proponents. This step in asynchronous sequential circuit design has to be done very.

With all of the potential advantages of asynchronous circuits one might wonder why synchronous systems predominate. Some asynchronous circuits may require extra power for certain operations. In general an asynchronous circuit does not need the precise timing control supported by flip-flops. For example even though a floating point unit on a processor might not be used in a given instruction stream the unit still must be operated by the clock. If transitions on two inputs arrive at almost the same time the circuit can go into the wrong state depending on slight differences in the propagation delays of the gates which are known as race.
