Abstract
One embodiment of the invention provides a system comprising at least one data-to-spike converter unit for converting input numeric data received by the system to spike event data. Each data-to-spike converter unit is configured to support one or more spike codes.
Claims20
A system comprising:
- a data-to-spike converter unit supporting different spike coding schemes, wherein the data-to-spike converter unit is configured to convert external input data received by the system into one or more spike event packets encoded in a spike coding scheme of the different spike coding schemes by processing the external input data in accordance with an equation corresponding to the spike coding scheme;
- and
- an output bus configured to transmit the one or more spike event packets to a plurality of neurosynaptic core circuits for processing;
- wherein a first spike event packet, encoded in a first spike coding scheme of the different spike coding schemes, is converted from first external input data received by the system by processing the first external input data in accordance with a first equation corresponding to the first spike coding scheme;
- and
- wherein a second spike event packet, encoded in a second spike coding scheme of the different spike coding schemes, is converted from second external input data received by the system by processing the second external input data in accordance with a second equation corresponding to the second spike coding scheme that is different from the first equation.
