Abstract

The drive control 11 addresses matrix 13, which has bistable elements arranged in a double triangular configuration. In such a matrix, two addresses are associated with a selected pair of drivers. One address is indicated when the drivers drive in the same relative direction. Another address is indicated when the two drivers drive in relatively opposite directions.

Addressing A Double Triangular Matrix

The drive control 11 addresses matrix 13, which has bistable elements arranged in a double triangular configuration. In such a matrix, two addresses are associated with a selected pair of drivers. One address is indicated when the drivers drive in the same relative direction. Another address is indicated when the two drivers drive in relatively opposite directions.

The thousands and hundreds positions of address register 15 are coupled to high-low compare register 17, and in parallel to drivers 21. The direction in which the driver, selected by the tens and units positions, drives current is always the same. The direction in which the driver, selected by the thousands and hundreds positions, drives current is controlled by high-low compare register 17 and control circuit 19.

If the output from the thousands and hundreds positions is higher numerically than the output from the tens and units positions, the driver selected by the thousands and hundreds positions drives in one, positive direction. If the output from the thousands and hundreds positions is lower numerically than the output from the tens and units positions, the driver selected by the thousands and hundreds positions drives in a relatively opposite, negative direction. Thus, cores are controllably selected in either matrix.
