Abstract
This invention relates to an improved program counter which is capable of both incrementing the program count as well as decrementing the program count. This functionality provides improve implementation of decision trees in computer logic. The value of an integer is determined and compared to a predetermined constant. For each of, for example, three conditions a different decision is made. One of those decisions enables the program counter to continue on the current program list. A second decision moves the counter to a new list and causes decremental movement of the counter. The final decision enables movement to the same location as the second decision but causes incremental movement of the counter.
