    Abstract: A spike timing dependent plasticity (STDP) rule is applied in a spiking neural network (SNN) that includes artificial synapses bi-directionally connecting artificial neurons in the SNN to model locations within a physical environment. A first neuron is activated to cause a spike wave to propagate from the first neuron to other neurons in the SNN. Propagation of the spike wave causes synaptic weights of a subset of the synapses to be increased based on the STDP rule. A second neuron is activated after propagation of the spike wave to cause a spike chain to propagate along a path from the second neuron to the first neuron, based on the changes to the synaptic weights. A physical path is determined from the second to the first neuron based on the spike chain, and a signal may be sent to a controller of an autonomous device to cause the autonomous to navigate the physical path.

    Abstract: Techniques and mechanisms for processing differential video data with a spiking neural network to provide action recognition functionality. In an embodiment, the spiking neural network is coupled to receive and process a first one or more spike trains which represent an encoded version of a sequence comprising frames of differential video data. In turn, the frames of differential video data are each based on a difference between a respective two frames of raw video data. Based on the processing of the first one or more spike trains, the spiking neural network may output a second one or more spike trains. In another embodiment, the second one or more spike trains are provided to train the spiked neural network to recognize an activity type, or to classify a video sequence as including a representation of an instance of the activity type.

    Abstract: A clock buffer or driver is gated pending reception of verifiable crypto keys. These clock buffer or divers remain gated, thus disabling a processor from any meaningful function, till crypto keys are decoded, verified, and applied to the clock buffer or driver. A low frequency pseudorandom frequency hopping time sequence is generated and used for randomizing spread-spectrum to modulate a reference clock (or output clock) of a frequency synthesizer. This hopping time sequence holds the key to unlocking the crypto keys. The PWM modulated crypto keys are carried by the hopping time sequence. To decode the PWM modulated crypto keys, the hopping time sequence is used. The reference clock which is modulated with crypto keys in the spread-spectrum is sent to a decoder (in a processor) along with the hopping time sequence. The crypto keys are decoded and then used to un-gate the clock buffer.
