Abstract

FIELD: computer science equipment engineering, possible use for engineering of VLSI, devices and systems.

SUBSTANCE: spatial commutation structure has programmable commutation environment, groups of outputs of which are electrically connected to groups of outputs for connecting typical replacement elements. It is made in form of a polyhedron with n sides, on which groups of outputs are mounted for connecting typical replacement elements, while programmable commutation environment is positioned in the center of polyhedron. Second variant is different because spatial commutation structure is made in form of polyhedron with n sides, circling line of which approaches a spheroid shape. Groups of outputs of programmable commutation environment in accordance to both variants are electrically connected to groups of outputs for connecting typical replacement elements by means of conductors, positioned in appropriate radially positioned channels.

Description

The invention relates to the field of computer technology and can be used in the design of VLSI, devices and systems.

Known multilayer printed circuit boards (MPP), containing several layers of metallization and groups of conclusions for connecting typical replacement elements: microcircuits, connectors, etc. Electrical connections in the MPP are obtained by tracing printed conductors over the area of each layer and connecting fragments of printed conductors located on different layers, for example, through metallized holes.

Known programmable switching matrix (PCM), selected as a prototype, containing a programmable switching environment, terminal groups which are electrically connected to terminal groups for connecting typical replacement elements [www: Aptix. ru]. PCM is manufactured using submicron technology and contains several layers of metallization. Electrical connections in PCM are obtained by connecting fragments of printed conductors by switching bi-directional keys located over the area of each metallization layer and between metallization layers in a certain optimal way.

In known devices, the existing level of technology imposes restrictions on the maximum permissible minimum physical dimensions of printed conductors, the distance between printed conductors, the length of printed conductors, etc. The traditionally accepted design involves wiring the topology of the implemented electrical circuit along the planes of the layers, which leads to a limitation of the resource by the number of sold electrical connections, a decrease in the surface area for the placement of typical replacement elements and the complexity of manufacturing technology.

The disadvantages of the known devices are the limited resource in terms of the number of electrical connections sold and plug-in typical replacement elements and the complexity of the manufacturing technology.

The objective of the invention is to increase the resource of the spatial switching structure in terms of the number of electrical connections sold and connected typical replacement elements and simplifying the manufacturing technology.

The problem is solved due to the fact that the spatial switching structure containing a programmable switching medium, the terminal groups of which are electrically connected to the terminal groups for connecting typical replacement elements, according to the invention is made in the form of a polyhedron with n-faces, on which terminal groups for connecting standard replacement elements, moreover, a programmable switching medium is placed in the center of the polyhedron.

The problem is also solved due to the fact that the spatial switching structure containing a programmable switching medium, the terminal groups of which are electrically connected with terminal groups for connecting typical replacement elements, according to the invention is made in the form of a polyhedron with n-faces, the envelope of which approaches a sphere which have pin groups for connecting typical replacement elements, the programmable switching environment being placed in the center of the polyhedron.

The terminal groups of the programmable switching medium are electrically connected to the terminal groups for connecting typical replacement elements by means of conductors placed in the corresponding radially arranged channels.

For example, when implementing the design of the device in the form of a polyhedron, the envelope of which approaches the sphere, the achievement of the objective of the invention consists of the following factors:

- the surface area for placing groups of terminals for connecting typical replacement elements will increase by about 4 times (the ratio of the surface area of the ball to the area of the radial section of the ball);

- the resource of a programmable switching medium according to the number of electrical connections sold (if implemented in accordance with the invention, RF patent No. 2092896) is specified by the number of matrix switch cells and is practically unlimited. The layout of the topology of the implemented electrical circuit is reduced to programming matrix switches. Placement of conductors is carried out in the space inside the polyhedron and does not change during the implementation of any electrical circuits;

- the use of a polyhedron whose envelope approaches a sphere, including regular polyhedrons: tetrahedrons, cubes, dodecahedrons, icosahedrons, etc. - allows you to achieve the same length of all sold electrical connections.

The proposed device with an increase in surface area to accommodate typical replacement elements by about 4 times allows the implementation of any electrical circuits with the maximum filling of their typical replacement elements.

A programmable switching environment, made, for example, according to the patent of the Russian Federation No. 2092896, figure 2, has a regular structure and can be manufactured by any technology that allows you to get matrix switches.

Thus, the inventions solved the problem of increasing the resource by the number of electrical connections sold and connected typical replacement elements and simplifying the manufacturing technology.

Figure 1 presents a design drawing of a spatial switching structure.

Figure 2 presents a diagram of an electric programmable switching environment.

The spatial switching structure (Fig. 1), made, for example, in the form of a cube 1, on the faces of which there are groups of terminals 2 for connecting typical replacement elements: microcircuits, connectors, etc. The programmable switching medium 3 is placed in the center of the cube 1. Group of terminals 4 of the programmable switching medium 3 by means of conductors 5 located in the corresponding radially arranged channels 6 is electrically connected to the group of terminals 2 for connecting typical replacement elements.

The work of the spatial switching structure (figure 1) is as follows.

Typical replacement elements are installed on the faces of the polyhedron, and the group of conclusions of each element is connected to the corresponding group of conclusions 2. The location of the typical replacement elements on the faces of the polyhedron can be arbitrary. By programming the matrix switches of the first (1.1 ... 1.F) and second (2.1 ... 2.Q.) Groups of matrix switches of the programmable switching medium (Fig. 2), the topology of the implemented electrical circuit is obtained.

If it is necessary to combine devices based on the spatial switching structure (Fig. 1) into more complex systems, the location of typical replacement elements on the faces of the polyhedron should allow the possibility of connecting these devices into quasiregular or regular structures.

The spatial switching structure can be made in the form of other polyhedra, including regular polyhedrons, whose envelope approaches a sphere.
