A new learning algorithm for neural networks of spin glass type is proposed. It found to relax exponentially towards the perceptron optimal stability using concept adaptive learning. The patterns can be presented either sequentially or in parallel. prove convergence given and method's performance studied numerically.
With the ongoing integration of (dynamic) reconfiguration into current system models, new methodologies and tools are needed to help designer during development process. This article introduces a language extension for SystemC along with design methodology describing simulating dynamically reconfigurable systems at all levels abstraction. The presented library provides maximum freedom description behavior its control, while featuring simulation runtime configuration, removal, exchange custom...
A general purpose neurocomputer, SYNAPSE-1, which exhibits a multiprocessor and memory architecture is presented. It offers wide flexibility with respect to neural algorithms speed-up factor of several orders magnitude — including learning. The computational power provided by 2-dimensional systolic array signal processors. Since the weights are stored outside these NSPs, size processing can be adapted individually application needs. programming language, embedded in C ++ has been defined for...
We present a space-efficient, FPGA-optimized architecture to detect collisions among virtual objects.

Software implementations that test two triangles for intersection often favour speed over exact calculation. They leave it to the user choose an or a fast depending on domain of application. Hardware can not opt make this distinction since users will always expect accelerator hardware be applicable in all possible settings. This paper introduces novel approach towards testing triangles. It is based separating axes and lends itself well implementation. To integrable into hierarchical...
