(54) DEVICE FOR READING INFORMATION

t

This invention relates to computing technology. And can be used with .W-J in magnetic storage devices.

There is a device for calculating information containing a bridge circuit, a buffer cascade is connected to one bridge diagonal, and another is not a delay, there are resistors in the bridge arms, and a common amplifier is connected to common points.

The closest technical solution to this is a block for reading information, containing coupling amplifiers connected to the bit-reading tires of the drive memory lines, to the inputs of the number register and to the gate signal former, reference reading amplifiers connected to the bit-reading line m reference numerical lines of the G2 accumulator, FROM THE DRIVE

The known devices do not allow reading signals to be reproduced in a memory device with a high degree of roominess. There are no blocks and elements in them that allow learning the time gating of reading signals depending on the level of noise in the discharge-reading buses.

The purpose of the invention is to improve the noise immunity of the device for reading information from an accumulator.

The goal is achieved by the fact that, in a device for reading information from a storage device, the reader contains read amplifiers whose only inputs

ts are connected to the discharge bus of the drive lines of the accumulator, the other output of the gate signal generator, and the outputs of the read amplifiers are connected to the inputs. A numeric register, reference amplifiers, connected to the discharge-readable buses of the standard numeric bar, introduced an inverter, an adder, a waiting multivibrator and a differential element whose output is connected to the input of the gate signal generator, and the input to the output of the strobe signal, and the input to the output of the strobe signal, and the input to the output of the strobe signal; the input of which is connected to the output of the adder, the first input of which is connected to the output of the first reference reading amplifier, and the second to the output of the inverter the input of the inverter is connected to the output of the second reference amplifier schitshani bodies.

The drawing shows a diagram of a device for retrieving information from a storage device.

The device contains read amplifiers 1, one inputs of which are connected to the bit-reading buses of 2 storage lines, and the second to the output of the strobe signal generator 3, the outputs of the read amplifiers 1 are connected to the inputs of the numerical register 4. The input of the gate signal 3 is connected to the output of the differentiating element 5, the input of which is connected to the output of the standby multivibrator 6. The input of the standby multivibrator G is connected to

the output of the adder 7, the first input of which is connected to the output of the first reference amplifier 8. The output of the second reference reading amplifier 8 is connected to the input of the inverter 9, the output of which is connected to the second input of the adder 7 "Percussion inputs and the second adder 7 are connected to the discharge 10 and 11 reference /; numeric ruler drive.

When reading, the signal together with the noise comes in by the discharge-reading lines 2 numerical lines on the first inputs of the amplifier 1; At the same time, on the discharge-reading lines 10 and 11 of the reference numerical lines of the accumulator, the reference signals 1 and 0 are fed to the inputs of the reference amplifiers reading 8. From the output of one of them, the signal through the inverter 9, and from the other directly, is fed to the first and second inputs of the adder 7,

The output signal from the adder 7 starts the waiting multivibrator 6, from the output of which the signal goes to the remote power element 5. Next, the received signal is fed to the input of the gate signal 3, from the output of which the pulse

the gating is fed to the second inputs of the amplifiers of the schitsit 1,

The interference immunity of the device is enhanced by the organization of floating gating. This arrangement allows the introduction of an inverter, a adder, a waiting multivibrator, and a differentiator element. The time selection of the readout signal is not carried out by the reference signal of the link 1, but by the difference signal, i.e. by the difference of the reference signal of the read 1 and the reference signal O. By this, the influence of the interference imposed on the reference signal of the link 1 is eliminated or reduced by the start time of the gate signal generator 3, since the interference received

to the inputs of the reference amplifiers of the readout 8 from the 10O bit-reading unit and 11 reference numeral lines of the storage device are self-suppressed in the summa®®. The time selection of the readout signal is performed on the leading edge of the pulse received from the waiting multivibrator 6 after differentiating it from the differentiating

element 5, after di (fermentation

pulse of the waiting multivibrator and its formation with the help of the shaping of the bodies of the strobe signal 3, the strobe signal is fed to the second inputs of the read amplifiers 1, from the outputs of which the information signals are fed to the inputs of the numeric register 4.
