05:05
The application of synchronous counters with asynchronous carryAll the discharges of synchronous or parallel counters within one microcircuit switch simultaneously. As the result, the total shift hesitation of a synchronous counter roughly equals to the delay of one bistable. That means synchronous counters are much faster than asynchronous ones. And their speed doesn't fall with the increase in the number of charges.The speed of synchronous counters with asynchronous carry falls between the speed values of asynchronous and fully synchronous counters. The time chart of a four-discharge synchronous counter with asynchronous carry shows that the discharges are simultaneously switched over the positive edge of the input signal (with a certain delay). The negative carry signal also has a delay relative to the negative input impulse. That means, in this case, the shift hesitation of a multibit counter increases with each new microcircuit, rather than with each new discharge.Binary-decimal counter IE6 and binary counter IE7 can serve as examples of synchronous counters with asynchronous carry. Both the counters are bidirectional and can do direct and reverse counting. It is possible to reset the counter to zero with the help of a positive signal at input R. There is also the parallel recording function. You can record code from inputs D1, D2, D4, and D8 with the help of the negative signal at input WR.Counters IE7 and IE6 can be connected in order to increase their capacity. To do so connect the carry outputs of the low-order counters producing low-order carry bits with the inverting inputs of the high-order counters producing high-order carry bits.Synchronous counters with asynchronous carry are wonderful output signal frequency dividers. They have a relatively high response speed and are quite easy to control.Another advantage is the reverse counting function. Using these counters you can build frequency dividers with the division factor that can be randomly changed with the help of entry code. This type of frequency dividers are widely used in analogue-digital systems working with analogue signals of various frequencies.A common task is to form a packet of input impulses with a set number of impulses. For example, it is necessary in order to organise information exchange in a serial code. This type of impulse packet former can be built with the help of synchronous counters with asynchronous carry.A former of time intervals with the length set by external ...

Application of Synchronous Counters
 
05:18
Application of Synchronous Counters Synchronous or parallel counters are known to be the fastest devices of the kind. The high speed is achieved by a substantial complication of the mircochip's internal structure. This results in the fact that they are more difficult to control if compared to the asynchronous counters and series-carry synchronous counters. That's why synchronous counters should only be used in the cases, when high performance and high digit switching speed is a must. Otherwise the complication of the control circuit is just not worth it. Let's look at some circuits based on synchronous counters. The synchronous counters enable a rather simple implementation of a controlled frequency divider with a conversion factor set by an entry code. In the circuit the carry signal CR produced by the senior counter is supplied to the write enable input EWR. The counters operate in the countdown mode (the zero level signal is supplied to the U/D input). When all the counters reach the null code, a carry signal CR is generated, which switches the devices into the mode of concurrently writing the control code. The next positive edge of the clock C records the entry code in the counters. This results in a new count cycle from the entry code to zero. The next circuit - a generator of a time interval of the set duration - demonstrates how the output carry signal of synchronous counters should be used when required is a single operation cycle. The generator's operation is triggered by a short negative pulse Start, which sets the control flip-flop to one and starts the input signal. The positive signal from the flip-flop output switches the 8-digit synchronous counter from the concurrent write mode to the count mode (on EWR input). The countdown is performed on the positive edge of the clock from the generator. When the counter reaches zero, the next positive edge of the clock writes the carry signal CR into the flip-flop. This concludes the output signal, and the counter switches to the concurrent write mode. The next operation cycle of the generator starts at the Start signal. The use of synchronous counters can be associated with their ability to concurrently write on the clock edge. In the concurrent write mode the counter is viewed as a register actuated by the clock edge. Due to ...

Synchronous Counters
 
02:44
Synchronous Counters Synchronous or parallel counters are known to be the fastest devices of the kind. Provided that the required conditions are met, gain in their capacity does not result in an increased total dwell. We can thus say, that it is the synchronous counters that operate as ideal counters, where all the discharges are actuated simultaneously or in parallel. At the same time the drawback of synchronous counters is that they are more difficult to control if compared to the asynchronous counters and series-carry synchronous counters. A time diagram describing the operation of a synchronous counter is different from the time diagram for a series-carry synchronous counter in the formation of the carry signal used in cascading counters. The carry signal CR in this case is generated when all the counter outputs are set to one (when counting forward) or to zero (when counting back). In the situation the clock input does not participate in generation of the carry signal. The standard microchip series includes several types of synchronous or parallel counters. Depending on the counting method, there exist binary or binary-decade counters, bidirectional and unidirectional counters. They also may or may not have a reset signal. All the counters count based on the positive edge of the clock, and all have a carry output CR and expansion inputs for cascading. Besides, all counters support parallel recording of data. The potential applications of synchronous (or parallel) counters are quite extensive. Suffice it to say that they can easily replace both, the asynchronous (or serial) counters and the series-carry synchronous counters. And if required is the high speed, they are hugely advantageous if compared to all the other kinds of these devices. The output pattern of synchronous counters is set simultaneously at any number of discharges without the need to apply additional output registers that are an absolute must in the case of asynchronous counters and series-carry synchronous ones.

Application of synchronous counters, slice former
 
02:04
Application of synchronous counters, slice formerSynchronous counters are the most high-speed counters. The capacity extension under the specific conditions doesn't lead to increasing full dwelling time. So we may consider that the synchronous counters work as perfect counters which have simultaneous bits.A circuit of a slice former of a particular duration can be based on synchronous counters. The circuit shows how to use an output carry signal of synchronous counters if a once-only (non-repeat) cycle of work is needed.Former starts upon a short negative pulse "- Start" flipping the control trigger to 1 and starting an output signal. A positive signal form trigger output switches 8-bit synchronous counter from the mode of parallel recording of an entry code to the counting mode (EWR -- on input). The counting is decreasing on the positive fronts of a clock signal from the generator.When the counter reaches 0, the next positive front of a clock signal will register a zero carry signal - CR in the trigger. Thereby, an output signal is completed, and the counter will be switched to the mode of parallel recording.The next operation cycle oа the former will start upon a signal "- Start". In this case the trigger, processing a carry signal, works simultaneously with the counters as it is clocked by the same (positive) front of a single clock signal. The output signal duration will lie within the interval from NT to (N+1)T, where T is a cycle of a clock signal from the generator, and N is an entry code from 0 to 2510.

Usage of synchronous counters, controlled ...
 
01:51
Usage of synchronous counters, controlled frequency divider. Synchronous counters are the most high-speed counters. Digit growth under certain conditions doesn't cause a full operational delay, i.e. synchronous counters can be reputed ideally working counters all digits of which act simultaneously. A controlled frequency divider with a scaling factor that is preset with input code is rather easily implemented in synchronous counters. A circuit is built on 3 ИЕ17 synchronous counters. CR carry signal of the main counter is given to EWR write enable input. Counters work in a countdown mode, logical zero signal is given to U/D input. When all counters reach null code it causes occurrence of CR carry signal that switch counters to a mode of concurrent write of input control code. When the next positive-edge-of C clock signal triggered input code is written in meters. It opens a new cycle of counting from input code to zero. Scale factor of a frequency divider for this circuit is (N+1), where N — input code that can take values from 1 to (2 raised to the n--1 power), where n — a number of code digits. A frequency divider can work in the following conditions: clock signal period can't be less than full transfer delay. Output duration of frequency divider signal is equal to clock frequency period.
