Description

The utility model relates to information processing devices based on a microcontroller.

Currently, various educational and debugging devices are widely used in higher educational institutions to train students in specialties and areas related to computer technology. These devices are based on various microprocessors. They allow you to study the architecture of the computer, the system of commands, the features of operation and application.

An analogue of the proposed device is the "Training and debugging device "Electronics-580" (Shirokov, Yu.F. Microprocessor tools and systems / Shirokov Yu.F., E.N. Osipov, V.I. Zhdanov, N.I. Gutovets / / Training and debugging device "Electronics-580 - 1985. - No. 2. - P. 80-84.).

This device contains a microprocessor, address buffer, data buffer, status word register, control logic, decoder, generator, ROM, RAM, RAM data buffer, DMA node, parallel interface, keyboard, display, power supply. The power supply generates three supply voltages and is made according to a compensation scheme. All components of the device are made on elements of low and medium degree of integration and discrete elements.

Disadvantages analog: the device has low reliability, complex design, high power consumption.

The closest to the claimed technical solution is a hardware emulator of the training stand with a graphic information output unit. (Utility model patent RU 200727, IPC G06F9/455, G09B23/00, p. 03.7.20, publ. 09.11.2020)

The emulator contains a microcontroller unit with the necessary software, an amplifier unit for matching information signals during indication, a display, a keyboard, a switching power supply unit, a serial interface unit, a power driver unit, and a graphic information output unit.

The disadvantage of the prototype is that when building a complex computing system, it is not possible to perform registration (recording) of data, as well as to implement long-term non-volatile data storage. These can be emulator software settings, event log, time-stamped data (registration of events, reading large amounts of input information from sensors). This information can be viewed later or in real time in order to analyze the functioning of the implemented system. The prototype under consideration does not have the technical means of storing such volumes of information, since the standard amount of RAM and ROM of modern microcontrollers is up to 4 KB (http://arduino.ru/Hardware/ArduinoBoardUno).

To solve this problem, it is advisable to include an additional memory block in the emulator. It is a standard module for writing and reading data from an SD card (Micro SD Card Reader) (https://3d-diy.ru/product/module-micro-sd-card-reader). The module allows you to work with SD cards up to 32 GB.

The technical result is expressed in an increase in the memory capacity of the device.

The technical result is achieved by the fact that in the hardware emulator of the training stand with an additional memory unit, containing a microcontroller unit with software, an amplifier unit, a switching power supply unit, a serial interface unit, a power driver unit, a graphic information output unit, a display, a keyboard, where the first information the output of the microcontroller unit is connected to the amplifier unit, the output of which is connected to the display input, the second information output of the microcontroller unit is connected to the keyboard input, the output of which is connected to the information input of the microcontroller unit, the third information output of the microcontroller unit is connected to the information input of the serial interface unit, the fourth information output of the microcontroller block is connected to the information input of the power driver block, the fifth information output of the microcontroller block is connected to the information input of the graphic information output block, the output of the switching power supply is connected Connected to the power inputs of the microcontroller block, amplifier block, display, keyboard, serial interface block, power driver block and graphic information output block, the additional memory block is enabled, the sixth information output of the microcontroller block is connected to the information input of the additional memory block, the output of the switching power supply is connected to the supply inputs of the additional memory unit

The hardware emulator of the training stand with an additional memory block contains the following blocks:

1- microcontroller block,

2- amplifier block,

3- display,

4- power supply,

5- keyboard,

6- block of serial interfaces,

7- block of power drivers,

8 - graphic information output block,

9 - block of additional memory.

The scheme of the hardware emulator of the training stand with an additional memory block is shown in Fig.

Double arrows show the passage of information signals, and single arrows show power lines. A feature of the claimed device is that the functions of the training and debugging device are expanded by introducing an additional memory block 9 into the device. The amplifier block 2 is designed to increase the load capacity of the output port of the microcontroller block 1 connected to the display 3 of the training stand. The microcontroller unit 1 contains the minimum required amount of permanent and RAM memory, as well as the required number of input-output ports for organizing communication with the display 3, keyboard 5, serial interface unit 6, power driver unit 7, graphic information output unit 8 and additional unit memory 9 training stand. Switching power supply 4 generates the supply voltage required for the operation of electronic devices.

The device functions as follows.

Microcontroller block 1 performs hardware emulation, i.e. from the point of view of a user or a student, work on the hardware emulator of the training stand on microcontroller 1 is completely identical to work on the “Electronics-580 training and debugging device”. Using the keyboard 5, machine codes of commands of the developed program are entered. The input information is reflected on the display 3 of the device. Then the user starts the entered program for execution. The program can work in three modes: step by step, with stops at control points, in real time. The result of the program execution, as well as the contents of the storage elements and the device memory is reflected on a digital character display. If necessary, preliminary debugging of the program in the first or second modes of operation can be performed. It is possible to connect to the device external electronic devices, for example, a personal computer and organize information exchange with them through the block of serial interfaces 6 for the purpose of debugging the emulator software. Through the block of power drivers 7 it is possible to send control actions to the power devices of automatic control and automation systems. To display graphic information (for example, graphs of the dependence of signals on time) in order to debug and analyze the functioning of the implemented ACS, a graphic information output block 8 is used. The data accumulated by the device during operation is recorded in the memory device of the additional memory block 9. This information can subsequently be analyzed using the emulator software and, if necessary, displayed through the graphic information output unit 8. It is also possible to send this information to a personal computer through the serial interface unit 6.

To implement all the above features, the hardware emulator has the appropriate software.

Due to the addition of a block of additional memory, compared with the analog, there is an increase in the amount of memory of the device.
