Description

The invention from:, to the field of digital computing and is intended for mass parallel processing of information.

A known cell of a homogeneous medium l, containing the trigger and logical elements AND and OR.

In devices built from known cells, information is ordered by performing a certain sequence of polls of an associative matrix in accordance with the so-called SeberLindquist algorithm. In this case, for ordering an array of N information elements, an average of 2.9 N commands is required.

For the p yeny of the task of highlighting an ordered list of elements within given boundaries P | And Pj in known devices is preliminarily entered into a special column of the associative matrix for all elements of the original array. Then, an ordered search is carried out (in descending order) of all elements, starting with P and the units of the label column are erased in the selected lines. Similarly, an orderly search is carried out (in order of increasing) of all elements, starting

with P:

as well as erased tags. AT

As a result, labels remain only for those elements that are located within the specified boundaries. After that, an ordered sampling of all the marked (isklh) elements is carried out. Since in general the entire array is viewed the number of commands is constant (2.9 N) and does not depend on the useful volume of the NO array, i.e. on how many elements satisfy the given conditions.

The disadvantage of such devices is a large consumption of time when solving information and logic problems.

The closest to the technical essence of the invention is the cell of the device for sorting information 2, containing a trigger, four AND elements and two OR elements. The first input of the cell is connected to the first inputs of the first and second elements AND The second input of the first element AND is connected to the second input of the cell and the first input of the first OR element, the second input of which is connected to the output of the third AND element and the first input of the second OR element, the second input of which is connected to the output of the fourth element And, the first input of which is connected to the third input of the cell and the first input of the third element And, and the second

the input is from the fourth input of the cell and the second input of the second element I, the output of which is connected to the zero input of the trigger, the single input of which is connected to the output of the first element I and the single output to the second input of the third element I.

The aim of the invention is to expand the functionality of a homogeneous environment when solving information and logical problems,

This goal is achieved by the fact that the fifth element AND and the third element OR, the first input of the fifth element AND are connected to the output of the third element AND, the second input is connected to the second input of the fourth element AND, and the output is connected to the first input of the third element. OR, the second input of which is connected to the first input of the check. The drawing shows the logical scheme of the proposed homogeneous medium cell, Cell 1 has inputs 2, 3, 4, 5 and 6 variables Z, X, v, v and U, respectively, and outputs 7, 8, 9, Yui 11 variables z x y / V and and, respectively, and contains a trigger 12 with input elements And 13 and 14, elements And 15, 16 and 17 and elements OR 18, 19 and 20. In a homogeneous environment, outputs 8 and 9 of each cell 1 are connected to inputs 3 and 4 neighboring vertical cells respectively, and the outputs 7, 10 and 11 - with inputs 2, 5 and 6 of the next horizontal cell, respectively. Inside each cell 1, the first inputs of elements AND 15 and 16 are connected to input 2, the output of element AND 15 is with the first inputs of elements OR 18 and And 19, the second input of element OR 18 is with input 3 of cells, and the second input of element OR 19 is with the output element And 16, The output element OR 18 (19) is connected to the output 8 (7) of the cell. The second input element And 15 is connected to a single output of the trigger 12, and the second input of the element And 16 - with input 4 and output 9 of the cell. The first input of the element And 17 soi dinene with the output of the element And 15, the second input - with the input of 4 cells, and the output with the first input of the element OR 20, the second input of which is connected to the input of the 5th cell, and the output - with the output of 10 whose cells the environment implements the functions x: Xvaz, (1) z-Z (qvv1, (2) v Vv / qv, (3) 9-, JJ, (4) S-oUv, (5) where C (is the trigger state 12. Functions (4) and (5) allow the paraphase recording of information

Trigger 12. For this, the direct code of the recorded binary digit is fed to input 3, the reverse one to input 4. And simultaneously a write pulse is fed to input b. The comparison indicator PP PP2. Is supplied bitwise to the inputs of the corresponding columns of the homogeneous medium in the reverse code.

Functions (1) and (2) together provide the selection of maximum information elements,

To clarify the role of function (3), which acts in conjunction with function (2), we construct a table ... From this table, it is clear that avp I in the x cases when with J p, dtp - 1 in the case when

Claims (2)

 Table The expression (2) shows that the signal at the output of the Z cell is 1 if there is a signal 1 at the input and, in addition, CJ $ p. Expression (3) shows that the signal at the output V of the cell is 1 if there is a signal 1 at the input V or a signal 1 at the input Z, and in addition, to perform the comparison operation, a signal 1 is supplied to all inputs Z of the left border of the homogeneous medium and on all the inputs of the left boundary there is a signal O, When comparing arbitrary numbers and P-Pi.p2, three cases are possible: 1, In all bits. This means that a r. According to expressions (2) and (3), the signal pr 1 and vnp-O, 2 are produced on the right border. In all higher bits (up to some j-th) p,, py (i.e. oi; ti , r r 0), This means that regardless of the ratio of further bits. Since 2 ,, 1, then, according to expressions (2) and (3), in J and cell 2-1 and. If in all further (junior) bits, then, if at least in one bit, then 2 Gn 0, 3, - In all big bits (up to some J-th) a p, «PJ (i.e. ctjOf p.). This means that regardless of the ratio of further bits,, According to expressions (2) and (3), O and: 0. Consequently, and v 0. Results of the above analysis are shown in Table 2, Table 2 Thus, the environment is homogeneous , built from the proposed cells, provides a solution for one command of the following types of information and logical problems: 1. Search for the maximum information element in the array. 2. Selection of all elements of information coinciding with a given attribute. 3. Splitting an array into three subsets, the first of which includes all elements of information that coincide with a given attribute, the second — all elements smaller than a given characteristic, and the third — all elements that are larger than a given attribute. Consider the examples of solving some common informational problems in a homogeneous environment, built of the proposed cells. 1. The ordering of information is carried out by alternately selecting the maximum information elements. The divided elements are excluded from the subsequent processing (for example, by turning off the signal Z on the left boundaries of the corresponding lines of the medium). To order an array of elements, N commands are required. 2. Allocation of the ordered list of elements located within the given boundaries. РА Ра To solve this problem, a comparison is first made with the sign PI, after which all the elements that satisfy the condition are excluded from further processing. It then makes a comparison with the sign r, and excludes all elements of A of the RP. In the remaining subset, the rotation is carried out (see WSE). Thus, to solve this problem, it takes about + 2 commands, where NO is the number of elements of the initial array that satisfy the specified conditions. J. Search for an element closest to a given characteristic P. At first, a comparison is made with the reference parameter P and all elements are excluded A P. Then, in the remaining array, the maximum element is evicted, which is the desired one. To solve the problem, 2 teams are required. 4. Associative processing of information. Since in a homogeneous environment, built from pre-expanded cells, iMets parallel search associative search operations, it can be used as an associative computing device matrix, i.e. provides an effective implementation of all known algorithms for associative information processing.
