The invention relates to computing and can be used in the construction of specialized stochastic devices.

The aim of the invention is to expand the scope by forming multidimensional random functions.

 The drawing shows a functional diagram of a random function generator.

The random function generator contains a synchronization unit 1, a generator of 2 random numbers, a memory unit 3, an arithmetic unit k, an argument task unit 5 made in the form of a permanent memory unit, a delay unit 6, a key, a harmonic signal generator 8 9 and key 10 „

Generator operation is

IL

in the following.

When a pulse is applied to the Start, the microprogram for controlling the generation and recording of random frequencies V (Vp .. ,, Vn) in the array memory is started.

From the sixth output of unit 1, a series of n pulses is fed to the polling input of generator 2. Each of the pulses of the series generates a vector of random frequencies Vj (v, ..., m). A series of n pulses from the seventh output of block 1 is fed to the recording input of block 3 of memory, ensuring that array V is inserted into block 2 of memory. Upon completion of the microcommand entering the last Vrt vector into block 3, the preparation stage is completed and the formation of f (x) is started. The firmware is automatically started by generating a random function V (x). In this case, the signal from the eleventh output of block 1 provides input of the argument vector x from block 5 to block 4. After that, the first cycle of formation of the quantity (x) begins. On the control pulse from the eighth output of block 1, the vector V is output from block 3 to the information input of block k,

With the next text from the seventh and ninth EXIT, D, OEZ of block 1, pulses are fed to the recording input of block 3 and to the second input of the block resolution. These pulses ensure the transmission of the vector V into the input register

block 3. In this case, an asynchronous exchange of information is performed in block k. After the micro-command of information exchange in block 3 is completed, from the thirteenth processing start output of block 1 to the processing start input of block k, a pulse is triggered, which starts the processing microprogram

information contained in the block C, in accordance with the algorithm

(X; +

M)

where 03 is the circular frequency of the generator 2.

Simultaneously, from the tenth output of block 1, a pulse is emitted, which opens generator 8. After the time required to complete the processing of information in block 4, from the fourteenth output of block 1, a pulse is sent to the input of block 1 selection enable to output information from the output microprocessor register block k. After that, it is possible to set the delay time T, dd in block 6. After the time Ј, necessary for

setting the delay time of the Tead, from the ninth and second outputs of block 1, pulses are simultaneously applied to the input of the start of the generator 8.

When the time expires, the strobe from the output of block 6 opens the key 7 and the value equal to sin ((.) Sin (V; x + 1 Gyu4) is applied to the information input of the adder 9. This completes the first generation cycle of the random function (x) „

The second and subsequent, up to p, generation cycles are similar to the first. After the completion of the last p-th cycle from the fifth output of block 1

a signal is applied to the input of the key 10, ensuring that it is opened and the sum accumulated in the adder 10 is equal to (x) at the output of the generator. After the time T0 expires, the pulse from the fourth block frm 1 wraps the adder 9 and the next cycle of generating the random function (x) begins. The change in the dimension of the argument mn, the number of terms in the sum n, and the length of the implementation of the random function (x) (the number of generation cycles) is carried out programmatically by changing the microprogram to control the generation of the random function.
