The purpose of the invention is to expand the didactic capabilities of the device.

Figure 1 shows the functional diagram of the device; FIG. 2 shows a scheme of a control unit for computing speed.

The device for teaching the basics of computing contains a generator 1 (single pulse generator), generators 2-5, distributor 6 pulses, switches 7 and 8 of the delay duration, specifying information register 9, switch 10, block 11 of interchangeable modules, plug-in modules 12 and 13, button 14 Record, indicators 15 and 16, unit 17 for controlling the speed of calculations, operating mode switch 18, counting limit setting buttons 19, rough counting indicator 20, accurate counting indicator 21, GOI Start button 22, generator unit 23, operator’s console 24. Block 17 contains triggers 25 and 26, nodes 27 and 28. Comparison, elements 29-31, counters 32 and 33, indicators 20 and 21 contain decoders 34 and 35, and elements 36 and 37 of the display.

The device in the evaluation of speed: twi calculations works as follows.

The device has two modes of operation: single and continuous.

In a single mode of operation, the installation times of codes in one device under investigation are examined.

the previous, in continuous mode, the comparative installation times of codes in two computer nodes with different types of transfer are investigated. The operation principle of the speed unit is based on the use of the main and the nano generators, which are triggered accordingly by the signals of the beginning and end of the measured time interval. The countdown time is fixed on indicators of a rough and accurate count. 2 or ..

Before starting work on the console 24, a module 12 is installed — the computer node to be examined, for example, a counter.

The impulse supplied to the input is reset from generator 1 through switch 10, module 12 is set to O.

The device allows you to work with four types of transfer: parallel, end-to-end, group and sequential.

 On the master data register 9, information is typed; by pressing the button 14, it is rewritten into module 12; for example, at point 8, the code 11111111 is set in it.

In order to estimate the transition time of module 12 from this state to a new one, i.e. 00000000, clamps 19 set the code 00000000, from generator I, through switch 10, we give a pulse to the input of Module 12's account and switch 18. When button 22 is pressed, generator 1 generates a pulse, by which trigger 25 is set to one, thereby permitting the passage of generator pulses 2 at a frequency of, for example, 10 MHz over: element 29. The decoder 34 converts a binary code, for example, into signals of a seven-segment code. Element 36 displays the coarse count time in 1/10 of the ISS. As soon as the transition to the new state in module 12 ends, the inputs of node 27 will have the same codes, and the signal from its output will switch trigger 25 to the zero state, element 29 will stop passing pulses from generator 2. This same signal from the output of node 27 will switch

the trigger 26 is in the unit state and will start the generator 3, which in this case is a vernier generator with a frequency of, for example, 11 MHz. Element 31 transmits pulses of generator 3, which are counted by counter 33. Decoder 35 converts a binary code, for example, into signals of a seven-segment code. Element 37 displays the exact readout time in O 1/100 ISS. As soon as the pulses of the generators 2 and 3 coincide in time at the element 30, the trigger 26 goes to the zero state and the counting time ends.

Thus, in a single mode of operation, the time of transition of devices to a new state from the previous one is measured. Depending on the type of transfer, this time will be different. To measure the transition time of other devices under study, it is necessary to replace the module 12 of the counter with another one.

In continuous mode, the comparative installation times of codes in two devices with different types of transfer are investigated.

On the console 24, modules 12 and 13 of the devices under study, such as meters, are installed.

Switch 18 selects the mode of comparative evaluation of speed. In module 12, a transfer must be selected that provides a higher speed than in module 13, for example, a correspondingly parallel and group transfer. Using the keys 19, we set the code to which the count will be produced, for example, when p 8 code is 10,000,000. When inputting the count account to a continuous sequence of pulses from one of the generators 4-5 through the switch 10, the following happens: 10,000,000 and a signal from the output of the node 27, the trigger 25 goes into one state. The counter 32 counts the pulses of the generator 2. As soon as it is set to the state 10,000,000 less than the high-speed module 13, the output of the node 28 occurs

operator’s console groups, and the inputs are with the outputs of the first and third elements I, respectively, the first inputs of which are connected to the outputs of the primary

As soon as the pulses of the oscillators 2 and 3 coincide in time on the element 30, the trigger 26 goes to the zero state and the counting time ends. Thus, the difference between the installation time of the codes will be displayed on the elements 36 and 37, namely: how much will a counter with a higher speed set to, for example, 10,000,000 faster than a counter that is slower;

In this mode, a comparative evaluation of the speed of any devices with different speeds is possible. The choice of a specific device under investigation is determined by the operator by installing one or another plug-in module.

Thus, the invention provides significant accuracy measurements of the speed of individual computer devices and their comparative speed.
