Mika Laiho and Eero Lethonen, University of Turku, Finland, will be talking about memristor-based neuromorphic chips at a Catalyst lunch event on Thursday, February 17, 2011 from noon to 1:00PM in the CELEST Lounge, 3rd Floor, 677 Beacon Street, Boston MA 02215. Details below.

A mixed-mode cellular image processor implementation is described. Each pixel-processor is equipped with locally adaptive image sensor, resources for local arithmetic operations and storage. In addition, the cells include e.g. programmable space-dependent neighborhood connections, ranked-order filter, rank identification and anisotropic resistive filtering. It is further described how CMOS-memristor hybrid technology could enable large neighborhood connectivity in a dense cellular processor array.

Mika Laiho: University of Turku, Finland
Mika Laiho received a DSc degree in electrical engineering from Helsinki University of Technology in 2003. He was appointed adjunct professor at the University of Turku in 2008. His research interests include computing with memristors, especially in connection with cellular and associative architectures.

Eero Lehtonen, University of Turku, Finland
Eero Lehtonen received an MSc in mathematics from the University of Turku, Finland, in 2006. He started graduate studies under Prof. Laiho's supervision in January 2009. He studies computation with memristive devices.
