Description

one

This invention relates to automation and computing.

A device for dividing is known, containing a register of the dividend, connected by inputs to input buses, and outputs to a comparison circuit, a divider register whose inputs are connected to an input bus, a result counter connected through logic to a clock generator, an adder and keys.

The proposed device is characterized in that the adder is connected by inputs through the keys to the register of the divider, and the outputs to the comparison circuit, the output of which is connected to the input of the counting logic of the output connected to the inputs of the keys.

This simplifies the device.

The drawing shows a block diagram of a device for dividing.

The device contains the registers of the dividend 1 and the divider 2, the result counter 5, the comparison circuit 4, the accumulator 5, the clock pulse generator 6, the keys 7 and the counting logic 8.

The device for dividing works as follows. The pulses from the generator 6 through the logic 8 of the resolution of the account arrive in the counter 3 and simultaneously on the keys 7. With each pulse, the information divider

the parallel code is transferred to the lower bits of the adder 5. Scheme 4 compares the number in the upper bits of the adder with the number of register / dividend.

The dividend X recorded in the register must be greater than the divisor, by a certain number of orders, determined by the required accuracy of the calculations. At the moment of equality of the numbers recorded in the adder and register 1, the comparison circuit closes the logic of resolution of the account, the compartment, the arrival of pulses in the counter and on the keys. The number recorded in the counter is thus dividing.

The proposed division device works both in a one-time calculation and in the case of continuously variable values of the dividend and the divisor. In the latter case, registers 1 and 2 are replaced by reversing

counters, and the rates of change of the dividend, the divider and the frequency of the pulse generator must be appropriately matched.
