The invention relates to computing and can be used in various systems for computing elementary functions.

The aim of the invention is to improve the speed of

On the gortech, there is a diagram of a device for dividing a variable by a number

The device contains the input 1 of the device number, the input 2 of the initial installation of the device 5 adder-subtractor S register 4, flip-flop 5, the first shift register b the clock input 7 of the device, the input 8 characters of the variable device j all the device 9, the second shift register 10 and input 11 is a variable device module.

The device operates as follows.

At the input 1 of the device, the value of the number Ke is supplied. The value of the module variable X from the input 11 of the device is written to the register 10, Trigger 5 is set to a single cocTOHirnie signal from the input 2 of the device. Since K is always positive, the sign of the result coincides with the sign of X, the Result is formed as a unit of number and the sign of X is entered into the register simultaneously with the entry of the signs in the register I Oo The division begins with the delivery of clock pulses, which are equal to the number of e-) x private bits., to the input 7 of the device

For convenience, further work is illustrated by an example of dividing X -OoHOIOI (.1с110101) by 5 (0101)., Totalizer-subtractor 3 is basically molset to have an arbitrary number of bits of Gu In the device under consideration is 9 symbolic bits (11 bits in total);

Invention Formula . A device for dividing a variable by an integer containing a totalizer-subtractor ;, register, first and second shift registers, a trigger; the output of the register is connected to the inputs of bits, except the younger one, of the first information input of the adder ™ 0 five 0 five 0 five the bits of which are connected to the information input of the trigger, the installation input 1 of which is connected to the input of the initial setup of the device, the clock input of which is connected to the input of the trigger reception enable, from the shift enable input of the first and second shift registers, the output of the first shift register is the output of the device The input of the device variable module is connected to the information input of the second shift register, characterized in that, in order to improve speed, the input sign of the device variable is connected to the mouth By setting the input of the first shift register, the information input of which is connected to the information input of the trigger, the direct and inverse outputs of which are connected respectively to the inputs of the subtraction and addition resolution of the totalizer-read: I, the second information input of which is connected to the input the device numbers, the outputs of the bits of the adder-subtractor are connected with a shift by one bit towards the higher bits with the inputs of the register bits, the output of the second shift register is connected to the input of the least significant bit of the first information input of the adder-subtractor
