Description

one

The invention relates to the field of automation and computer technology and is intended to convert numbers.

A device for mutual conversions of decimal-binary and ternary-binary numbers, consisting of adders and converters of nine-binary digits into a ternary-binary code, is known. A disadvantage of the known device is low speed.

In order to increase the speed, the first stage of the device contains two nine-digit adders of decimal digits interconnected by transfer chains, the input of the first term of the first adder is connected to the bus of the highest (n-1) and decimal binary digit of the number being transferred, the input of the first the second adder is connected to the bus (p-2) -and ten-binary digits, the input of the first adder and the transfer adder of the second adder are connected to the bus “О, the second adder of the second adder is connected to the older bus (p-1) - digits of the translated number, at the t-th stage, there are (t + 2) nine-adder accumulators sequentially interconnected by transfer chains, the inputs of the first term of all nine-adders, except the youngest, are connected to the corresponding outputs of the adders of the previous step, and the youngest connectors the bus of the transferable number with the number {p- (t + 1), the inputs of the second term of the first hexadecimal adder and the transfer inputs of the younger (i + 2) -ro adder are connected to the “O” bar, the inputs of the second term of all nineth adders, except the first, connected to the corresponding inputs of the first addend of neighboring higher hexadecimal adders, the output of the sum of each dByric adder of the last (n-1) -th stage is connected to the converter of nine-binary digits to the ternary-binary code.

These compounds of nine-digit su.mmators and transducers make it possible to speed up the operation of converting decimal binary numbers to ternary binary code.

The drawing shows a diagram of the device.

It contains converters 1-6 diacritical-binary digits into a ternary-binary code, as well as diacrit adders of 7-23 decimal-binary digits. The inputs of the device are the inputs of 24 decimal-binary digits, and the ternary-binary digits of the result are obtained at the outlets 25.

The operation of the device consists in the fact that the input decimal number is converted into a decimal number system, and then the binary value of the bit is converted into a ternary-binary code.

The first part of the conversion is performed at the (-1) -th stage of nine-adder adders. In the first stage, consisting of adders 22 and 23, a two-digit decimal number is converted into a hexadecimal code, consisting of two leading digits and L "-2 of the initial decimal number. The result corresponds to the calculation of the value

10 + An-z

in the nine-fold number system. The result numbers are obtained at the output of the transfer and the sum of the dirich adder 22, as well as at the output of the sum of the adder 23. The next decimal digit is added to the number found on the right, and the resulting four-digit number goes to the second conversion stage.

The input of the 1st stage, consisting of adders 13-17, is given a deviatic number L, obtained at the (i-1) -th stage. The number L- on the right is added by the digit An- (i + i). The measured result is obtained at the outputs of the sum of adders 13-17 and corresponds to the value

10b + fn. (, Part 1 ,,

which is calculated in the number system with a base of nine. The result obtained together with the digit An- (i + z) is transmitted to the () -K stage.

A complete binary-binary result is generated at the outputs of nine-to-ten adders of 7–12 steps (n-1).

The second part of the conversion — the bitwise translation of the hexadecimal number into the three-binary code — is performed at the 9th transform transducer stage 1-6.

A full binary binary result, equivalent to the original decimal binary number, is obtained at outputs 25.

Obviously, the result of the conversion is stored in the output bits until the input number changes in the input. The conversion rate is determined only by the speed of operation of the logic elements from which the nine-adders of the device are built.
