The present invention relates to a torus-coupled modular array implementation method that can be easily adapted to any configuration.

[Technical background of the invention and its problems]

In a parallel data processing device where modules are arranged in a two-dimensional manner, torus coupling, which has the effect of reducing the distance between modules 101 by half, is used as a coupling method between modules, as shown in Fig. 1. is often used. In the torus structure,
Although the upper, lower, left, and right edges do not exist, in the following explanation, the upper, lower, left, and right edges of the module array will be referred to as the edges of the module group. , 105 is called a lower side terminal, 106 is called a left side terminal, and 107 is called a right side terminal. 102 is a vertically adjacent connection line, 103
is called the horizontal adjacent connection line. Conventionally, as a module array mounting method having such a torus structure, methods as shown in FIGS. 2 to 4 have been used. 2 shows the case where the modules are arranged in 1 row and 8 columns, FIG. 3 shows the case where the modules are arranged in 2 rows and 8 rows, and FIG. 4 shows the case when they are arranged in 2 rows and 16 columns. Module 101 in any case
The upper terminal 104 connects to the lower terminal 105 of the module adjacent to the upper side of the module, the lower terminal 105 connects to the upper terminal 104 of the module adjacent to the lower side of the module, and the left terminal 106 connects to the lower terminal 105 of the module adjacent to the upper side of the module. The right side terminal 107 of the module adjacent to the left side of the module, and the right side terminal 107
are respectively connected to the left side terminals 106 of the module adjacent to the right side of the module, forming a torus structure. As can be seen from the figures, with this type of mounting method, as the number of modules increases, the connection distance between modules increases depending on the location, and there is a risk of deterioration of electrical characteristics during information transmission between modules. Ta. Furthermore, when considering an increase in the number of modules, the connection method changes greatly as the number of modules increases, resulting in a drawback of poor expandability.

It is. Further, counting only the module rows B, the odd numbered module row from the left side is the odd numbered module row B, and the even numbered module row is the even numbered module row B. In FIG. 5, in the vertically adjacent connection line indicated by a broken line, except for modules at the upper and lower ends, in module row A, the upper terminal 104 of each module is connected to the lower terminal of the module adjacent to the upper side of the module. The lower terminal 105 is connected to the upper terminal 104 of the module adjacent to the lower side of the module. In module row B, the upper terminal 104 of each module is connected to the lower side of each module. It is connected to the lower side terminal 105 of the adjacent module, and the lower side terminal 105 is connected to the upper side terminal 104 of the module adjacent to the upper side of the module. In the modules at the upper and lower ends, the upper terminal 10 of the module at the upper end of module row A
4 is connected to the lower terminal 105 of the module at the upper end of module row B, and the lower terminal 105 of the module at the lower end of module row A is connected to the upper terminal 104 of the module at the lower end of module row B. In the horizontal adjacent direction connections shown by solid lines in FIG. Connect to the left terminal 106 of the fourth module in the same row, that is, connect the left terminal 106 of each module to the left terminal 107 of the fourth module in the same row to the left when counting from the module. Connecting.

In the modules in module row B, the right side terminal 107 of each module is connected to the left side terminal 106 of the fourth module on the same row counting from the module, that is, the left side terminal 106 of each module Connect it to the left side terminal of the fourth module on the same row, counting from the module in question.

Embodiment 1 in FIG. 5 in which the odd module row A and the odd module row B are exchanged is the same as that in FIG. 6, so a description thereof will be omitted.

A specific example will be explained below. Here, we will consider a board on which a plurality of components as shown in FIG. 7 are mounted as each module, and a case where these are mounted in parallel as shown in FIG. 8 will be described.
In FIG. 7, 104 is a terminal for the upper side, 107 is a terminal for the right side, 106 is a terminal for the left side, and 105 is a terminal for the lower side. 200 is a component constituting the module. In FIG. 8, 101 is a board (module), and 301 is a backboard for parallel mounting. In the following explanation, connections between boards are shown in a view seen from the direction of the arrow in FIG. 7. FIG. 9 shows a third embodiment of the present invention, in which eight boards are mounted as a set.

This is equivalent to the connection method of the second embodiment in which the right side terminal of each module in module row B is used as the left side terminal, and the left side terminal is used as the right side terminal. When eight boards are considered as a set, the connection lines shown by solid lines are fixed wiring, and the connection lines shown by broken lines are lines that are changed when the number of boards is expanded. The first board was expanded by using four of the eight boards shown in Figure 9 as a unit.
This is figure 0. The part indicated by the bold line is the part where the connection is changed.

Therefore, in the implementation shown in Fig. 9, when the connections between boards are absorbed into the backboard shown in Fig. 8, the fixed wiring part shown in Fig. 9 is left as the printed circuit board wiring inside the backboard, and the expansion If the parts that may be changed in connection can be connected using connectors and cables, any expansion can be accommodated by simply creating one type of board and one type of backboard as shown in FIG. 7. Moreover, the connection distance between all the boards can always be kept within 4d, where d is the board spacing.

〔Effect of the invention〕

As explained above, by using the present invention to implement a matrix-like torus-coupled array circuit with 2n rows and m columns, the connection distance between each module can be minimized, and the distance can be maintained regardless of the scale of the module. Since the distance between modules is always 4d or less, it is possible to prevent deterioration of electrical characteristics etc. due to connection between modules. Further, connection changes due to expansion are small and regular, making expansion easy. Furthermore, as mentioned earlier, when mounting is performed using the board shown in FIG. 7, there is an advantage that it is possible to carry out the mounting with consideration to expansion using only one type of board and backboard.
