1Use of energy by moving object
If traditional computer methods are used to simulate random walks, then computation can be performed, but electrical power consumption is high and computation efficiency is low
Solution Approach 1:
The patent replaces traditional von Neumann architecture computers with neuromorphic computing systems that mimic biological neural networks. This substitution fundamentally changes the computational paradigm from sequential processing to parallel event-driven processing, dramatically reducing power consumption while improving computation efficiency for random walk simulations.
Solution Approach 2:
The simulation domain is divided into multiple mesh nodes, each independently processing random walk events. This segmentation enables parallel computation across numerous nodes simultaneously, reducing overall computation time and power consumption per node while maintaining total simulation accuracy.
2Temperature
If traditional computer methods are used to simulate random walks, then computation can be performed, but heat output increases and equipment efficiency reduces
Solution Approach 1:
The patent replaces traditional high-heat-generating computer processors with neuromorphic computing hardware that operates at lower temperatures. The event-driven spiking neural network architecture reduces unnecessary computational operations, thereby reducing heat generation and improving equipment reliability and efficiency.
3Loss of time
If traditional computer methods are used to simulate random walks, then computation can be performed, but computation time increases and resources are wasted
Solution Approach 1:
The patent implements event-driven computation where mesh nodes pre-process and filter random walk events before full simulation. Spiking neurons only activate when relevant events occur, eliminating unnecessary computational steps and reducing both computation time and resource consumption while maintaining simulation accuracy.
Solution Approach 2:
The neuromorphic system maintains continuous simulation processing through asynchronous event handling, eliminating idle computation periods. Random walk events are processed continuously as they occur across mesh nodes, maximizing resource utilization and reducing total computation time without wasting computational resources.

AI summary
A method for simulating a random walk using spiking neuromorphic hardware is provided. The method comprises receiving, by a buffer count neuron, spiking inputs from upstream mesh nodes, wherein the inputs include information packets comprising information associated with a simulation of a random walk process. A buffer generator neuron generates spikes until the buffer count reaches a first predefined threshold, after which it sends buffer spiking outputs to a spike count neuron. The spike count neuron counts the buffer spiking outputs, and a spike generator neuron generates spikes until the spike count neuron reaches a second specified threshold. The spike generator neuron then sends counter spiking outputs to a probability neuron, which selects downstream mesh nodes to receive the counter spiking outputs, wherein the spiking outputs include updated information packets. The probability neuron then sends the spiking outputs to the selected downstream nodes.
