(54) DEVICE FOR COLLECTION AND PROCESSING OF INFORMATION

I

. The invention relates to the field of computer technology and can be used in information-measuring systems and in automatic control systems. ,

A device for collecting and processing information {, containing a synchronization unit, telegraph code geerator, amplifier, converter, control unit, electronic clock unit, interrogator, selector unit, interface unit, subcommutator unit,) information sensors, memory unit, unit comparisons, perforators, tape recorder and display unit.

The closest to the invention in technical essence and the achieved result is a device for collecting and processing information 2, which contains a microprogrammed control unit, the first output of which is connected to the first inputs of the RAM and arithmetic-logical unit, the command register, the first input of which is connected to the output of the adder , address counter and element OR. The first input of the firmware control unit is connected to the first output of the command register, the second output of which is connected with the first inputs of the OR element and the address counter. The output of the counter address soideii with the second input of the OR element and with the first input of the adder. The output of the memory block S is connected to the second inputs of the arithmetic logic unit and the command register. The second and third inputs of the RAM block are connected to the outputs of the OR element and AriQ of the logic unit, and the second input of the address counter is the device input.

The disadvantage of these devices is greater equipment redundancy.

The purpose of the invention is to reduce the number of equipment.

The goal is achieved by the fact that the proposed device contains a switch, a super-fast memory block and an index register. Groups in (switch's switchboard is a device gathering group, the first and first switch inputs and outputs are connected to the second output and input of the microprogram control unit, respectively. The second and third outputs are switched, respectively, to the second input of the adder and to the third input of the arithmetic unit. The second one the output of the register of the command is connected to the second input of the switch and to the input of the super-operative block. This type of output is connected to the second input of the command register and through the index register to the third input m adder.

The block diagram of the device is presented in the drawing.

The device contains a microprogram control unit 1, a RAM unit 2, an arithmetic logic unit 3, a command register 4, an address counter 5, an adder 6, an index register 7, a switch 8, an operative memory block 9, and OR elements .10. :,: .

The device provides information collection in two ways.,.

The first method is that information is removed from the sources of information in the event that a request is received from them. It is considered that the request is usually sent, in the event that the information has changed from the previous one.

The second method is that information is removed from the sensors at an arbitrary point in time, for example, if for a given argument value it is necessary to have a function value.

Information collection methods are implemented using two commands. The first method is performed with the help of the command Resolving the Preamble, the second method is performed with the help of the command Central Survey. These HMeiqT commands are the structure of the mathematics .km; andes and exits when passing the program. Program commands are selected from block 2 and stored in command register 4. The operation code of the command enters the microprogram control unit 1, where, using this code, a series of microoperations is generated that performs this operation. Counter 5 of the address forms the address of the next command by adding one to the previous one or by rewriting the address from the register of 4 commands ..

When the interrupt block 1 command is executed, the switch 8 is polled. If there are no requests in the switch for 8 years, then from the regisgram 4 command, the address of block 5 of the address receives the cell address of block 2, where the next program command is located. If the switch Sanpock 8 in the switch 8, then the switch 8 selects the request with the highest priority and generates the code of the source of the information that sent the request. The 3i4jT code is fed to the input of the adder 6. At the same time, the address code from the index register 7 arrives at its other input. The total address obtained at the output of the adder 6 is the address of one of the registers of block 9, the reference to which

is done through register 4 commands.

With a zero value of the contents of the register 7, the addresses of the registers of block 9 are the numbers of the sources of information. The number of registers of block 9 is equal to the number of sources of information. If any sources of information are to be disabled (the program does not serve them), then the command "Enable interrupt." In the event that the information from the sources of information is to be removed, the command of unconditional transfer to the program serving the given source of information should be in the corresponding register of block 9. This command is rewritten to register 4 commands. In parallel with the selection of a command from block 9 of the command “Interrupt enable connects the information channel of the selected information source to the input of block 3 and.-Writes the information code into it. Thus, the command “Resolve Interrupt” prepares the initial situation for executing the program for servicing the selected source of information.

When several programs are working with Information Reference, the program can have its own block 9, and it is accessed by writing the corresponding index (basis) to the register 7. Block 9 can be implemented on a permanent memory, and the index register 7 may be missing. In this case, each program uses the same block 9, having previously written into it “its address of unconditional jump.

In this case, block 9 can be implemented either in the RAM or in the permanent memory.

In order to increase speed in any case, block 9 can be implemented on: triggers.

D. When executing the command “Centralized polling, the operation code comes from register 4 of the command. In block 1. The latter generates a series of control signals. The contents of the address part of the register 4 of the command, where the code of the source of information is recorded, from which it is required to read information. A switch 8 connects the information channel of the required source to the input of block 3. By the signals from block 1, the information is stored in block 3, and from block 2 the operational

1 memory is selected by the program command line.

The invention was used in an information-measuring system for antenna measurements. During the year we tested the high technical performance of the device. Thus, the measurement rate in the system is up to 250 kHz: i.e., equal in time to two
