The Silicon Vertex Trigger (SVT) in the CDF experiment at Fermilab performs fast and precise track finding and fitting at the second trigger level and has been a crucial element in data acquisition for Run II physics' However, as luminosity rises, multiple interactions increase the complexity of events and thus the SVT processing time, reducing the amount of data CDF can record. The SVT upgrade aims to increase the SVT processing power to restore the original CDF DAQ capability at high luminosity. We describe the SVT upgrade, consisting of a new Associative Memory 16 times larger than the existing one, and new faster Track Fitter and Hit Buffer boards to take advantage of these patterns. We describe the existing system, the upgrade, tests and. performance. (c) 2006 Published by Elsevier B.V.
