PCNN neurocomputers - Event driven and parallel architectures

The simulation of large spiking neural networks (PCNN) especially for vision purposes is limited by the computing power of general purpose computer systems [5,9,10]. Therefore, the simulation of real world scenarios requires dedicated simulator systems. This article presents architectures of software and hardware implementations for PCNN simulator systems. The implementations are based on a common event driven approach using spike events for communication and processing flow. Furthermore, parallel approaches utilizing the spike event computing are introduced for simulation acceleration. Implementations of software simulators on workstation clusters and parallel computers and hardware accelerators based on FPGAs, ASICs and DSPs are described. The presented results demonstrate the capability to simulate large vision networks close to real world/real time requirements.
