Description

The block diagram of the device shredstilen on the drawing.

It contains a sector register /, a register of rows 2, a register of columns 3, an information input block 4, a power supply block 5, a matrix indicator board 6, divided into k sectors, each of which includes the element "And and the two-place familiarity matrix; yydrssnuyu bus 7, information bus 8 n elements “And 9.

Sector 1 register is intended for storing and storing the sector address and changing this address during the sequential entry of information. The address input of the sector register is connected to the address bus, and each address input 13 is the output from, the first input of the elements “And the corresponding sector. On the control input, the register of the reactor is connected to the control output of the register of rows 2.

The register of rows 2 and the register of columns 5 are used to record and store the addresses of the row and column of the familiarity selected and change these addresses upon sequential input of information. The address inputs of these registers are connected to the address bus, the address output of the register line is connected to the address inputs-szukh / dimensional matrices of indicators of all ss-ctorosis, and the address output of the register of columns with the second input of the elements of “And all sectors. By the lowest input, the row register 2 is connected to the control output of the register of columns 3, and Г to the equal output with the control input of the sector /. .Register 3 columns. It is occupied by the control over us, iBxojy with the control of the output of the input block of information 4, and. For the control output with the control input of the registrar line. 2

 A type of information 4 is intended for Afithema. of the sign, for converting it into a code for illumination, for storing the illumination at the time of the record, as well as for the forms of transferring IM11; y; 1) (c)) B. According to the information input, the information input unit is connected with the information bus, and at the information output, with the information inputs of the two-dimensional matrixes of all sectors. The control output of the information input unit is associated with the control input of the register of columns 3.

The power supply unit 5 is designed to formulate a saturation matching the physical characteristics of the indicators. Matrix indicator board 6 (intended for displaying and storing information. The first inputs of the elements of the PI sectors are combined with the corresponding "BL X Board of the sector selection register, the second inputs of the elements in" And all sectors are connected to the address output of the column register 3. Address inputs two-dimensional datrits of all sectors are connected to the address output of the register of rows 2. The output of the elements of "And each cejcTopia is connected to the uni-final input of a two-dimensional matrix of the same sector. Information: matsi-rye inputs of two-dimensional matrices

all sectors are connected to the information output of the input block.

The device works as follows. To enter information on the matrix scoreboard on the address data bar. The command to select the display cell is received. This command sets the corresponding bits of the sector, rows and columns to the "one" unit. The output from the output of the row register set to unit is fed to the iBce cells of the selected row of the matrix display, and the voltage from the output set to column discharge unit of the column 3 through the element "And, the other input which is output is set to the result set in" the sector register bit unit, is fed to the indication cells of the selected column of this sector. The display cell, located at the intersection of the selected rows and column, is prepared for recording information.

According to (Command "recording information on the information bus, the pa-block of entering information and receiving a sign code. Unit 4, when receiving a sign code, converts it into an illumination code and simultaneously sends an erase signal to the matrix board and then an illumination code.

Erasing followed by recording of new information occurs only in the selected display cell.

iB the moment when the recording of the Information is completed in the selected display cell, unit 4 forms a pulse. which shifts the register of columns to one; discharge, thus preparing the next cell indgkatsil selected sector. At the end of the record in the last cell of the selected row, the column register output shifts the register of rows by one bit and sets the first digit of the column register to “unit”, thereby selecting the first indication cell of the next row of the selected sector.

By eye: tschan1 and writing to the last cell of the last line of the selected sector, the row register non-complement signal shifts the sector register by one bit and sets: 1Is the first bit of the register of rows into the first unit, prepares and thus the first cell of the next selected sector to receive information.

The recording of the foreign trademark is carried out by analogy recording in the previous code.

When selectively recording on separate cells of the matrix display, it is necessary to repeat the command for selecting the display cell.

Subject and d on and e and

The device for displaying information, contains, its block of information, one output of which is connected to the matrix indicator board, the other to the register of columns, and the input to the information bus,

the inputs of the registers of columns and rows are connected to the address bus; one output of the register of rows is connected to an indicator board, which is different from the fact that, in order to simplify the device, it contains elements “AND and the sector register, whose inputs 1 are connected to

address bus and other output of the register of lines, and outputs - with one input of the corresponding elements “And, the outputs of which | are connected to the matrix indicator board; other inputs of the elements “And are connected to another OUTPUT of the register of columns.
