Description

The invention relates to computing and is intended to display information from a computer, it can be used in design and construction automation systems, in automated data processing, in dialog systems.

The purpose of the invention is to increase the speed and simplify the device.

The drawing shows the block diagram of the device.

The device contains a memory block 1, a first decoder 2, a modulation unit Ze, a pulse distributor 4, a synchronization unit 5, an address switch 6, a television indicator 7, a register 8, a second decoder 9.

The device works as follows.

The synchronization unit 5 generates pulses corresponding to the required screen sampling of the television indicator 7 and controls the scanning of the latter. These pulses are fed to the pulse distributor 4d by temporarily assigning it to a television clock signal,

In the memory block 1, each point of the image corresponds to one bit, encoding its brightness;

verticals The coordinate origin of the screen grid is in the lower left corner. At the same time, the mathematical coordinates (X, Y) of the points of the screen lie within the limits: О Х 2 - 1,. Y 2 memory 1 is 2 bits,

In the mode of reading information from memory 1, converting it into video 4 and displaying on the screen of television indicator 7, the device operates identically to the known device

The recording of information in the memory unit 1 from the computer is performed as follows.

In the address field of the computer, to work with the device, 2 addresses are allocated by which the device is accessed. For example, for an Electronics-60 type computer with a common bus channel, when accessing a device, it can be depleted by the address 177400g - 177777 memory cube, it will be 2 then horizontal along 2 points

divided for connecting external devices. In this case, the device refers to the lower eight bits of the address, and the upper eight bits define the zone where these addresses are located. Each address of the address corresponds to a line of the image stored in memory block 1.

The first inputs of the register 8 are supplied with m lower-order address addresses, and the inputs of the decoder 9 are supplied with the highest address bits from the computer. At the input of the decoder 2, the lower ones are supplied, and the first input of the address 6 switch is the higher information bits from the computer. .

When writing information to the memory unit 1 from the computer, the addresses of the address zone are supplied to the inputs of the decoder 9, and the first input of the register 8 is the address of the address corresponding to the line of the image in which the record is made. The address of the address is recorded in register 8 by a signal from the output of the decoder 9. According to the information buses, the value of the X coordinate of the recorded point is output from the computer, the lower p bits being fed to the input of the decoder 2, the value of the information bit is fed to the first input of the pulse distributor 4 ( O or), which encodes the luminance of the point and-according to the signal. The recording requirement, received at the second input of the pulse distributor, connects the address of the record through the switch of address 6 to memory block 1 and writes to the bit of the selected word, 2 nd decoder.

Thus, the point is recorded in one machine cycle of output, due to the fact that the Y coordinate of the point is specified in the address field, and the X coordinate of the point is specified in the information field. When the channel width of a computer is equal to 16 bits, which corresponds to such mini- and micro-computers as CM-3, CM-4, Electronics-60, etc., the execution time for the edge of one command is saved. the point. So, with the regeneration on the screen of all points, with the issuance command time equal to 7 µs, and with n in the speed in comparison with the known device, it is 448 ms (2 times). At the same time, for issuing points from a computer, it is required to perform 2 times fewer issuing commands, which, respectively, 2 times increases its effective performance. In addition, in the present invention, a significant reduction in the equipment volume is achieved, since the third register, the second register, the first and second adders, the comparison node, the counter, the trigger and the valve are excluded from the known device.
