New trigger processor algorithm for a tracking detector in a solenoidal magnetic field

This paper describes a new method of calculating triggers for a tracking detector in a magnetic field. The method is serial and requires one clock cycle per layer. It uses roughly the same resources in a Field Programmable Gate Array as the more conventional logical equation approach. It has 2 main advantages over the logical equation approach. First, missing track elements have no affect on the amount of calculation required and the resolution degrades in a predictable manner. Second, this method allows implementing information from the third (non bend) coordinated as a simple extension to the basic algorithm.
