Abstract :
We propose a new generation of VLSI processors for pattern recognition, based on associative memory architecture, optimized for online track finding in high-energy physics experiments. We describe the architecture, the technology studies and the prototype design of a new associative memory project: it maximizes the pattern density on the ASIC, minimizes the power consumption and improves the functionality for the fast tracker processor proposed to upgrade the ATLAS trigger at LHC.
