The invention relates to digital computing and is intended for mass parallel processing of information.

The aim of the invention is to extend the functionality by performing data movement operations.

The drawing shows the functional diagram of the cell of uniform structure.

The cell has inputs 1-6 (k, z, x, y, v, u, respectively), outputs 7- II (z, x, y, v, and respectively), trigger 12, elements AND 13-20, elements OR 21 -23, elements NOT 24 and 25, elements AND 26 and 27, elements OR 28, AND 29, OR 30, NOT 31 and 32.

In a homogeneous structure, the outlets 8 and 9 of the cell are connected to the inlets 3 and 4 of the adjacent vertically cell, respectively, and the outlets 7, 10 and 11 are connected to the inlets 2.5 and 6 of the neighboring cell horizontally, respectively.

cells

Cell homogeneous structure works as follows.

Functions (4) and (5) allow paraphase writing of information into triggers of 12 rows of a homogeneous structure. For this, the direct code of the written binary word is fed to the bits on the inputs of the 3 cells and the reverse code to the inputs of the 4 cells of the corresponding columns of the homogeneous structure. Simultaneously to inputs 6

all cells of the selected row are given a write enable pulse, and to inputs 1 a zero signal.

The device can operate in different modes, depending on the value of the control signal k and the control signal and.

In information retrieval mode

to inputs 1 of the whole cells of a uniform structure, the control signal k O is supplied, and inputs 6 - the control signal U 0. The functions (1) - (3) are taken as follows:

(one)

x x v za; z z (a V y); v v vay

(2) (3)

At the same time, the cells of the homogeneous h: the structures ensure the fulfillment of the following information-logical operations in the homogeneous structure.

Search for the maximum element. To accomplish this operation, the elements of the array to be processed must be pre-written in lines, with the leading bits on the left, in the trigger 12 of a uniform structure. If now in each column we connect through the element NOT the outputs 8 and 9 of the lower cell and apply to the inputs 2 all the cells of the left column and to the inputs 3

of all the cells of the upper row, the boundary signals z I and X О, respectively, then at the end of the transients the signal z 1 at the outputs of 7 cells of the right column is set

in the lines that contain the maximum information elements.

Search for the minimum item. It is performed similarly to the previous one, if all elements of the array are written

in the trigger 12 reverse code.

Splitting an array into three subsets. To perform this operation, the array is written in the same way as when searching for the maximum element.

The comparison indication is applied bit by bit to the inputs of the 4 upper cells, respectively, to the columns in the reverse code. If we now apply to the inputs 2 and 5 of all the cells of the left column the boundary

signals, respectively, at the end of the transient, where elements larger than a given attribute are contained, signals v 1 are set, if the signals of v o and z o are smaller than the specified attribute, the signals v o and z 1 are the same.

In the transformation mode of the data structures to the inputs 1 of all cells of the homogeneous structure, the control signals k 1 and U 0 are supplied.

Functions (1) - (5) take the form:

X x v z; z zx;

 V i zxy;

q, qi

a, a

t-i

If you add an arbitrary binary vector to the inputs of 2 all cells of the left column and the boundary signals X O to the inputs of 3 cells of the upper row, then in the first (left) column of the homogeneous structure, the first binary source unit is separated (condition zx 1) in the second column is the second one, and so on. Indeed, in the first (left) column, according to (), the variables x retains the value O until. In some ith cell, where z 1 is first encountered, x changes the value by 1 and saves 1 to the lower limit. This means that the unit cell of the first column, in which the condition is fulfilled, the horizontal channel z of the selected i-th cell in accordance with (2) is locked by a signal, therefore the first I of the source binary vector does not spread further horizontally. In all cells of the first column, located below i, and cells, and, consequently, z z. This means that a copy of the initial binary vector is fed to the inputs 2 of the second column with the exception of its first (upper) unit. Similar transformations occur in the second, third, etc. columns of homogeneous structure: in some ith cell of the second column, the third vector of the original vector is imposed (condition), third of the first vector, and so on. Moreover, it is obvious i, i i ...,

The following operations transform data structures.

Expansion. The task that the device solves in this case is to connect m ordered input channels with any ordered group m output channels (out of the total number n). The number of input channels 1,, i2, 1. . . , i (i, - i - i,...), to which the input channels 1,2, ... are to be connected, are given by an n-bit binary vector containing 1 in the corresponding bits (control vector). This vector is fed in bitwise to the inputs 2 of its left boundary of a uniform structure, m input channels are connected bitwise to the inputs of 4 cells of the upper boundary. To the inputs of the 5 cells of the left border, the boundary signals Ud 0 are supplied. In this case, in each cell of the homogeneous structure, where the condition is fulfilled, according to (3), v y takes place, i.e. the signal rotates from the vertical channel y to the horizontal channel V. Obviously, the outputs of 10 cells of the right border will be sent in the i, th line of the signals of the 1st input channel, in the i2-th line - signals of the 2nd channel and t . e., which corresponds to the problem to be solved.

Compression. The task that the device solves in this case is to connect any ordered group of input channels (of the total number n) with m consecutive output channels. Input Channel Numbers

i,, ij,. . . , (i, i z i 3. i). which must be connected to the output channels 1,2, ..., ha, are given by n-bit binary vectors containing 1 in the corresponding bits. In this case, this control vector is fed in the reverse code to the inputs of 3 cells of the upper boundary of a homogeneous structure, n input channels are connected in parallel to the inputs of 4 cells of the upper boundary. To the inputs 2 and 5 of all the cells of the left border, the boundary signals and V 0 are supplied, respectively. In those columns where the control vector contains O,. This means that there cannot be selected cells in the columns. The remaining columns behave as follows. Let in the vector, the units are located on,

condition according to (1) and occurs in the i, s, and to the left of the cell of the 1st line, i, and to the left of the cell of the 2nd line, etc., therefore, the signals i ,, ij-ro, etc. input channels will be directed to the outputs of 10 cells of the right border in 1,2-th, etc. lines, which corresponds to the problem solved in this case.

Weighing (counting the number of units in a binary vector). The argument vector is fed in reverse code to the inputs of the 3 upper boundary cells. All the inputs of the 2 cells of the left border and the inputs of the 4 cells of the upper border are respectively boundary signals and 1. If the argument vector contains 1 units, then the condition will be fulfilled exactly in the first 1 lines of the homogeneous structure. In all the other lines below, the condition cannot arise. This means that signals will be sent to channels v only in the first 1 lines. Consequently, the outputs IO of its right boundary form in this case a scale along which the weight (number of units) of a given binary vector is calculated.

In the mode of moving data to the inputs 6 of all its homogeneous structure, a signal is given, and to the inputs of 1 cells that are configured to work in the specified mode - a short-term signal. At the same time, the cells, on which the signals of adjustment are sent and, realize the functions (1) - (5) in the form:

Xv z;

a;

V V zxy;

d) (2 (3)

(4) (5)

Thus, setting the cells of a homogeneous structure to perform functions (l) - (5) provides the ability to write to the triggers of these cells the information entering them on input 2, and at the same time forming the output state 7 of the trigger state of the corresponding cell B previous cycle work homogeneous structure. This property provides the following operations in a homogeneous structure.

Write information to a column. The task that the device solves in this case is to write in a certain i-th column of the uniform n-bit structure of the binary vector arriving at the second inputs.

cells of the leftmost column of a homogeneous structure. To solve this problem, an n-bit binary vector is fed to the inputs of 2 cells of the leftmost column of a homogeneous structure, a signal is also fed to inputs 6, a signal to the inputs of 4 cells of a homogeneous structure, 1 cells of an i-column of a homogeneous structure in which the initial binary vector is written, a pulse signal is applied. As a result of this setting, functions (l) - (5) are implemented in i-ro cells, and in the remaining

cells of homogeneous structure - function (1-5) in the form:

x x v za; (r)

z z; (2)

V V V za; q, X

(3) (4) (5)

Thus, in accordance with (l) - (5), the binary vector supplied to the inputs of 2 cells of the leftmost column of a uniform structure without input changes to the inputs of 2 cells of the i-ro column and in accordance with (l) - (5) the triggers of 12 of these cells upon receipt of a recording pulse at the input, which is required for solving the set task.

It should be noted that when a signal is applied to the inputs 1 of all cells of a homogeneous structure, the input binary vector will be written in parallel to all the columns of the homogeneous structure.

Shift data. The task that the device solves in this case is to write into each (i, 3) -th cell of a uniform structure.

The cp of implementing this task sends a signal to the inputs I of all cells of a homogeneous structure, a pulse is given to the inputs of 6 cells of the leftmost column, and the output of each cell of the homogeneous structure generates the trigger state of this cell, which enters the neighboring cell and 2 is entered into its trigger. The pulse duration during the operation of a homogeneous structure in this mode should be, respectively, 26, +2 s +, where C ,, G ;, e, respectively, the delay times of signals in the OR, AND, NOT circuits, on which cells of a homogeneous structure are realized. Thus, as a result of setting the cells of a homogeneous structure with signals and a homogeneous structure in this case, the matrix is shifted to a shift register, in which the operation of shifting to the right by one position of the stored data is performed, which is required to solve the problem.

It should be noted that when the outputs of the 7 cells of the rightmost column of the homogeneous structure are connected to the inputs of the leftmost column, the homogeneous structure is converted into a matrix shift ring register. In addition, in the case of forming at the inputs of 6 cells of the leftmost column of a homogeneous structure of a series of pulses in a homogeneous structure, a shift will be realized by n positions, where n is the number of pulses in the specified series.
