After a successfully completed subcycle i
    The index of the first power factor for the decomposition of the associated summation unit is always stored in the recorder by 14 steps. It is the uncompressed unit 7 of the first index to the autoscriptive value in the form
    The second clock cycle sequence has the goal of breaking the associated unit. The associated unit, recorded in register 11 of the associated unit, is partitioned into a decimal prefix and an elementary unit. The clock cycle in a modified form can be passed several times. When controlled from the control unit 21, the generator 10, the adder 14,

    a sequence of metrics for base units, wherein the contents of register 8 of the autoscriptive unit are added in adder 14 and stored in register 8 of the autoscriptive unit.
    The processing of the autoscriptive value involves the adder 14, the registers of the number 3 and the autoscriptive unit 8, the accumulators of the number 24 and the autoscriptive unit. To perform operations with the values, the input keyboard has keys for summing, subtracting multiply, dividing, raising to a power, and extracting the root (not shown separately ).
    partitioning the existing connected unit so that adder 14 for up to m subcycles for each i subcycle, starting with i 1, adds the first i characters, forming the serial number for the memory of decimal prefixes 18, and using 55 of the first i characters of the associated unit, according to a given Bit scheme, forms a control sign for
    received decimal prefixes and, in time, parallel to this process in parallel or successively adds all the signs of the associated unit, starting with the (i- | -l) -ro sign, forming the sequence number for memory 16, and using the generator 10 from the sequence of all the signs of the compound unit, starting with the (i + 1) -th sign in the given Bit scheme, form the sign for the received elementary unit.

    a sequence of metrics for base units, wherein the contents of register 8 of the autoscriptive unit are added in adder 14 and stored in register 8 of the autoscriptive unit.
    The adder 14, the registers of the number 3 and the autoscriptive unit 8, the accumulators of the number 24 and the autoscriptive unit participate in the process of processing the autoscriptive value.
    In order to carry out operations with values, the input keyboard has keys for summing, subtracting multiplying, dividing, raising to a power, and extracting the root (not shown separately).
    The scheme adds or subtracts without limiting the type of values of one system — two autoscriptive values of the same type, multiplies or divides two autoscriptive values of the same or a different type, and raises or extracts the root from the autoscriptive value and translates the result as an autoscriptive value into the accumulator 24 numerical value and to the accumulator 25 of the autoscriptive unit 5.
    When performing the operations of addition and subtraction of two autoscriptive grandeur, adder 14 compares the content of the inbound transformation as follows.
    During several cycles, adder 14 extracts a compressed unit from the contents of accumulator 25 of autoscriptive unit 25 and stores it in the address register, reveals for K cycles whether the unit is in the memory of homoscriptive units. If it is contained, then the homoscriptive unit is translated into register 5 of the homoscriptive unit 8 of the autoscriptive unit from the content, and the indicator to the first factor
    the accumulator of the accumulator 25 of the autoscriptive unit, adds (subtracts) if these units are equal, the contents of the register are 3 numbers with the contents of the accumulator 24 and stores the received amount in the accumulator 24.
    the products of the degrees of the homoscriptive unit are in register 7 of the first indicator. A generator 27 of decimal prefixes separates a certain factor involving the adder 14 from the contents of the accumulator.
    When performing a multiplication operation of 5–24 numbers, depending on its value and (dividing) two autoscriptive values of the contents of register 7, the first display is the 14 Mmator by separate elements of the warehouse body. Instead, in register 5 homoscriptive (subtracts) the contents of the register of the 8-unit unit, the designation of the deci-autoscriptive unit is entered, taking into account the order of the standard prefix. The auto reflection process with the contents of the accumulator 25 of the autoscriptive script value in the form of a homoscriptive unit, the adder 14 multiplies (divides) this value ends, the contents of the accumulator 24 numbers by the contents of the register 3 numbers, the results of the Generator 28 units produce a homologous unit. N clock cycles take place, and n is equal to the number of basic units of the used system of units.
    found in the accumulators of the autoscriptive unit 23 and the number 24.
    During the operation of the construction of 25 In each cycle, a factor is created, the degree (extraction of the root) of the autoscriptive value adder 14 checks whether the register 3 contains numbers of an integral numerical index with the mantissa "1" and whether all bits of the register of the autoscriptive unit are equal
     degrees if the corresponding element in accumulator 25 for an autoscriptive unit is non-zero.
    The first cycle starts with the last base unit of the specified type. In each
    tsi 8 is always "O When these pre-30 cycles are performed, which includes the generation of parcels, the adder 14 multiplies the existing factors one by one, first the factor of
    transferred from the accumulator 25 of the autoscriptive unit to the register 5 of the homoscriptive unit, after which the designation of the basic unit is taken from the generator 28 units, then the factor indicator is written to the first indicator register 7, and the homo (divides) the contents of the 2D autoscriptive unit accumulator into the 3 register index and writes the result in the drive 25 autoscriptive units, then the adder 14 raises (extracts the root) the contents of the accumulator 24 numbers to the power in accordance with the contents of the register 3 numbers and stores the result ltat number in the accumulator 24.
    The script unit is generated in the optimal form of the record.
    Under the optimal recording form, an optimal recording format is added. Next, the device converts autoscript, computed multiplication of degrees with a simulated value recorded from the tips of 24 and autoscriptive unit 25, into a homoscriptive one, while finding a suitable homoscriptive unit. The numerical value of the homoscriptive value is memorized; a number of factors, and these factors contain only certain units. These units can be supporting (SI units with a separate name), for example
    it is in the accumulator on the 24th, and its homoscreen is 45 newton, volt, Pascal; the main (second, tivny unit is stored in the 5 ampere register) additional (radians), homoscriptive units. For example, for a value of this type.
    If for this autoscriptive vein, as the resistivity, it is always impossible to find the generating unit, the unit is ohm-meter, the volt-meter to ampere, the homoscript value is appropriate, then the generator of 26 units generates with the unit-generator of 28 units the optimum form the key unit in the form of the product is a display of a homoscreen unit and it works by a driver consisting of the basic units .. p.; 1 the following way.
    The generator 27 of the decimal prefixes an attempt to detach a unit from the contents of the accumulator 24 hours, if the given unit contains a factor that does not depend on its values and less (K-1) of the basic units from the group enters it into the first bit of the register 5 reference units, all the supporting units of the same group contain the same basic (juvnye units. When this
    homoscriptive unit, as the designation for the decimal prefix.
    Output transformation occurs as follows.
    During several cycles, adder 14 extracts a compressed unit from the contents of accumulator 25 of autoscriptive unit 25 and stores it in the address register, reveals for K cycles whether the unit is in the memory of homoscriptive units. If it is contained, then the homoscriptive unit is translated into register 5 of the homoscriptive unit of the degrees of the homoscriptive unit — into register 7 of the first indicator. A generator 27 of decimal prefixes separates a certain factor involving the adder 14 from the contents of the accumulator.
    24 numbers depending on its value and on the contents of register 7 of the first indicator. Instead, the designation of the decimal prefix is entered into the register 5 of the homoscriptive unit. The process of reflecting the autoscriptive value in the form of a homoscriptive value ends there,

    The script unit is generated in the optimal form of the record.
    Under the optimal form of writing, the product of degrees with a miuslov is implied, the deviation of the given autoscriptive unit from the individual reference units by points is estimated, while a point means that of the considered basic units, one has a deviation of “1. There are points of shortage and points of excess.
