2 Contains ・ Back ground ・ What is a Neurosynaptic computing chip? ・ Practical use research works -Application for human work organ -Application for computer ・ Product example ・ Problem ・ Sammary November 30, 2011Colloquium

3 Back ground ・ Development focus on human brain Human brain's mechanism is good at processing of flexible consideration Disadvantage point of usual neumann computer ・ Application of other field This chip work very similar to human nerve Embed in human body with complicated device November 30, 2011Colloquium Neurosynaptic computing chip(Neuro chip) Neuron: Brain's nerve cell Synapse: Connection part between neuron and neuron Possible application to medical

4 Neurosynaptic computing chip November 30, 2011Colloquium ・ Neuro chip build new network constantly oneself -Perception -Action Learning ability -Recognition ・ Recognize any pattern ・ Expectation from experience Fig. Neuro conection Fig. Neuro network on silicon chip

5 Contains ・ Back ground ・ What is a Neurosynaptic computing chip? ・ Practical use research works -Application of human work organ -Application of computer ・ Problem ・ Summary November 30, 2011Colloquium

6 Human work organ November 30, 2011Colloquium Building new networks Possible embed medical parts(pacemaker, biosensor) in human body natural Org an Medical parts Chip Human bodyDevice : Neuron Fig. Neuron put on biochip

7 Human work organ November 30, 2011Colloquium Building new networks Possible embed medical parts(pacemaker, biosensor) in human body natural Org an Medical parts Chip Human bodyDevice : Neuron Fig. Neuron put on biochip

8 Neuro computer November 30, 2011Colloquium ・ Advantage of usual computer -Calculate high speed Many calculation ・ Advantage of Neuro computer -Recognize pattern of figure, sound, etc... -Deciding volition ability Input figure1Input figure2 Same person Can computer judge same person? Front view Input figure1 Side view

9 Product example IBM product “Neurosynaptic core” ・ Have neuro and synapse made silicon - Neuro number is Program synapse number is 262,144 - Learning ability synapse number is 65,536 ・ Run scatter and parallel processsing -Recognize pattern -Remember association -Classification November 30, 2011Colloquium Neuro: calculate work Synapse: memory work

10 Problem ・ Big scale to run parallel scattering process -Have to put many neuman -Occur delay communication between neuman and neuman Process different between human signal and device signal ・ Many neuro's processing speed - Each neuman's process speed is slower than anything digital, but human body make high speed parallel processing use neuron and synapse November 30, 2011Colloquium

11 Summary Neuro chip can process some problem that usual neumann computer can't process good This technology's development affect control problem - Hardware to device Robot control, Figure and sound pattern processing... - human to device Biosensor, artificial retina, artificial arms and legs...
