This paper presents an implementation of a neuro-inspired algorithm
called VITE (Vector Integration To End Point) in FPGA in the spikes domain.
VITE aims to generate a non-planned trajectory for reaching tasks in robots.
The algorithm has been adapted to work completely in the spike domain under
Simulink simulations. The FPGA implementation consists in 4 VITE in parallel
for controlling a 4-degree-of-freedom stereo-vision robot. This work represents
the main layer of a complex spike-based architecture for robot neuro-inspired
reaching tasks in FPGAs. It has been implemented in two Xilinx FPGA
families: Virtex-5 and Spartan-6. Resources consumption comparative between
both devices is presented. Results obtained for Spartan device could allow
controlling complex robotic structures with up to 96 degrees of freedom per
FPGA, providing, in parallel, high speed connectivity with other neuromorphic
systems sending movement references. An exponential and gamma distribution
test over the inter spike interval has been performed to proof the approach to the
neural code proposed.Ministerio de Economía y Competitividad TEC2012-37868-C04-0
