A digital computer can control an array of circuit modules through the use of two sets of pan-array signals, known as R and C. The C lines run vertically and connect to all modules in the same column, and the R lines run horizontally and connect to all chips in the same row of the array. By asserting a particular pair of R and C lines, a specific module can be selected to receive control data from one of these lines. Each module includes a support circuit to latch when R and C are asserted together, and then to route data from one line into a variety of storage registers. A particular example is described that uses the control system as the basis of a data storage and retrieval system. |
