Description

We describe a VLSI processor for pattern recognition based on Content Addressable Memory (CAM) architecture, optimized for on-line track finding in high-energy physics experiments. We have developed this device using 65 nm technology combining a full custom CAM cell with standard-cell control logic. The customized design maximizes the pattern density, minimizes the power consumption and implements the functionalities needed for the planned Fast Tracker, an ATLAS trigger upgrade project at LHC. We introduce a new variable resolution pattern matching technique using “don’t care” bits to set the pattern-matching window for each pattern and each layer can be independently.
