Description

one

The invention relates to computing, in particular, to devices for inputting information into a digital computer (DVM), and can be used in computer systems for processing film information coming from communication channels.

A device 1 for inputting information into a digital computer is known, comprising a counter, a counter control circuit, a reception circuit, an overhead signal indicator, a query generation cell, a shift register, a linear buffer and a read control circuit.

The disadvantage of the device is a significant cost of equipment in its implementation.

The closest to the invention in technical essence and the achieved result is a device 2 for inputting information into a digital computer comprising an input register, a command register, a control unit, the first, second outputs and the first, the second inputs of which are connected respectively to the control inputs of the input register and register commands, with the first output of the command register and with the first clock input of the device, information, code inputs and address output of the device are connected respectively to the information input of the input register, with watts rymi input and output of the instruction register.

When processing information coming from the communication channel from a film-scanning device with the results of a physical experiment in a bubble chamber, or certain conditions, it is required to enter information not from the entire frame, but only data from a certain frame area into the computational computer. For example, it is necessary to take over the service area information, where the frame number, the lens number, the magnetic field, the current B magnets, or the information where the track is twisted or intersected with another track are indicated. To analyze a physical experiment,

Photographing the entire volume of the camera in three projections. After processing a frame, any of the projections (or frames of two projections) to restore the track in a digital computer

it is enough to enter information from individual zones from the remaining frames.

The drawback of the device lies in the lack of an ability to control input to the digital computer not all, but some specific information coming from the communication channel. This leads to a reduction in the functionality of the device.

In addition, if you enter information from all frames completely, then to store it in

The digital computer requires a significant amount of memory, and software time searching for information of the track of interest of one of the frames is required.

The purpose of the invention is to expand the functionality of the device.

This is achieved by the fact that the device contains a coordinate counter X, a coordinate counter Y, a strobe shaping unit, a regreg output and four comparison circuits. The information and control inputs and output of the output register are connected respectively to the outputs of the input register and the strobe formation unit and to the information output of the device, and for the first time the inputs of the comparison circuits are associated with the corresponding outputs of the comaid register and the outputs with the corresponding outputs of the strobe forming unit. The second inputs of the first and second comparison circuits are connected to the output of the X counter, the second inputs of the third and fourth comparison circuits are connected to the output of the coordinate counter U. The third, fourth, fifth, outputs of the control unit are connected respectively to the fifth input of the gate forming unit, the control inputs of the coordinate counter X and the coordinate counter Y, and the counting inputs of the coordinate counter X and the coordinate counter Y are connected respectively to the triggering and second clock inputs of the device.

FIG. 1 is a block diagram of the device; in fig. 2 shows an example of the arrangement of codes in a command register; in fig. 3 - the conditional distribution of zones (shaded areas) for the input of film information into the digital computer from a frame with various combines of codes in the register of IDs.

A device for entering information into a digital computer contains (fit. 1) an input register 1 with information input 2, with control input 3 and output 4; command register 5 with control input 6, code input 7, and outputs 8-13; control unit 14 with inputs 15, 16 and outputs 17-21; counter 22 coordinates X with inputs 23, 24 and output 25; counter 26 coordinates Y with a counting input 27, control input 28 and output 29; comparison circuit 30 with inputs 31, 32 and output 33; circuit 34 compared with inputs 35, 36 and output 37; circuit 38 compared with inputs 39, 40 and output 41; circuit 42 compared with inputs 43, 44 and output 45; output register 46 with information input 47, torque input 48 and output 49; strobe formation unit 50 with inputs 51-55 and output 56.

Input 2 of register 1, input 7, output 9 of register 5, input 15 of block 14, input 23 of counter 22, input 27 of counter 26, output 49 of register 46 are the corresponding information, code inputs of the device, the address output of the device, their first clock trigger, the second clock inputs of the device and information output of the device.

FIG. 2 and 3 are indicated: / Ci is the operation code and the memory location into which information is recorded; Kz is the coordinate code from which

The output of information in the digital computer along the X axis begins; Кз - the coordinate code from which the output of information to the digital computer along the X axis is repaired; Ki is the coordinate code from which the output of information in the digital computer along the Y axis begins; Kj is the coordinate code from which the output of information in the digital computer along the Y axis is stopped.

The remaining symbols are similar to those in FIG. one.

The device works as follows.

The command is received from the control unit of the digital computer to the input 7 of the register 5 according to the reception enable signal received at the input 6 from the output 18 of the control unit 14. From exit 8

the register 5 to the input 16 of the block 14 is given an operation code, specifying the operation mode of the device. When a clock signal arrives from the channel at input 15 of block 14, output 17 is generated at the reception resolution of information received at input 3 of register 1, according to which information from input 2 of the communication channel is received into register 1.

This is equal to the codes received at the input 32 of the comparison circuit 30 from the output 10 of the register 5

and the input 31 from the output 25 of the counter 22, the output 33 of the comparison circuit 30, generates a start out signal that enters the input 52 of the block 50. With the input signal 51 and the block 50 from the output 19 of the block 14, a receive strobe signal is outputted at the output 56 of the block 50. When this signal arrives at input 48 of register 46, information from output 4 of register 1 is taken to input 47 of register 46. The reception strobe signal will be generated until

But from the output 37 of the comparison circuit 34, the blocking signal will not arrive at the input 53 of the block 50. The blocking signal is generated when the codes received at the input 36 of the comparison circuit 34 are equal from the output 11 of the register 5 and the input

35 from the output of the counter 22.

Similarly, the formation of a start signal from the output 41 of the comparison circuit 38, which is fed to the input 54, takes place

block 50, and the blocking signal from the output 45 of the comparison circuit 42 passing to the input 55 of the block 50. The input 40 of the comparison circuit 38 and the input 44 of the comparison circuit 42 are connected respectively to the outputs 12, 13 of the register 5, and the inputs 39 and 43 with the output 29 counters 26.

To enable the operation of the counters 22 and 26 from the communication channel, the start signal of the scanning line is input to the input 23 of the counter 22, and the clock signal to the input 27 of the counter 26.

From outputs 21 and 20 of block 14, account control signals are supplied to input 24 of counter 22 and input 28 of counter 26. Information from output 49 of register 46 is passed to memory of the digital computer but to the address transmitted from output 9 of register 5.

The proposed device provides a reduction in the amount of transmitted information due to hardware control input specified areas of information. The application of the invention will make it possible to reduce the amount of memory of a digital computer for the collection of information, as well as the time of a digital computer for software search of information.
