This article reviews recent progress in the development of the computing framework vector symbolic architectures (VSA) (also known as hyperdimensional computing). This framework is well suited for implementation in stochastic, emerging hardware, and it naturally expresses the types of cognitive operations required for artificial intelligence (AI)....

The biologically inspired spiking neurons used in neuromorphic computing are nonlinear filters with dynamic state variables, which is distinct from the stateless neuron models used in deep learning. The new version of Intel’s neuromorphic research processor, Loihi 2, supports an extended range of stateful spiking neuron models with programmable dyn...

The biologically inspired spiking neurons used in neuromorphic computing are nonlinear filters with dynamic state variables - very different from the stateless neuron models used in deep learning.

Deep artificial neural networks apply principles of the brain's information processing that led to breakthroughs in machine learning spanning many problem domains. Neuromorphic computing aims to take this a step further to chips more directly inspired by the form and function of biological neural circuits, so they can process new knowledge, adapt,...

Neuromorphic computing applies insights from neuroscience to uncover innovations in computing technology. In the brain, billions of interconnected neurons perform rapid computations at extremely low energy levels by leveraging properties that are foreign to conventional computing systems, such as temporal spiking codes and finely parallelized proce...

In order for the neuromorphic research field to advance into the mainstream of computing, it needs to start quantifying gains, standardize on benchmarks and focus on feasible application challenges.

We present a compiler for Loihi, a novel manycore neuromorphic processor that features a programmable, on-chip learning engine for training and executing spiking neural networks (SNNs). An SNN is distinguished from other neural networks in that (1) its independent computing units, or "neurons", communicate with others only through spike messages; a...

Loihi is a 60 mm2 chip fabricated in Intels 14nm process that advances the state-of-the-art modeling of spiking neural networks in silicon. It integrates a wide range of novel features for the field, such as hierarchical connectivity, dendritic compartments, synaptic delays, and most importantly programmable synaptic learning rules. Running a spiki...

In a spiking neural network (SNN), individual neurons operate autonomously and only communicate with other neurons sparingly and asynchronously via spike signals. These characteristics render a massively parallel hardware implementation of SNN a potentially powerful computer, albeit a non von Neumann one. But can one guarantee that a SNN computer s...

The design of a commercially-shipping 72-port 10G Ethernet switch router integrated circuit is presented.

Slack matching is the problem of adding pipeline buffers to an asynchronous pipelined design in order to prevent stalls and improve performance. This paper addresses the problem of minimizing the cost of additional pipeline buffers needed to achieve a given performance target.
