Blog Review: Sept. 23
By Jesse Allen - 23 Sep, 2020 - Comments: 0

Arm's Matthew Mattina introduces a method to reduce the cost of neural network inference by combining both low-precision representation and the complexity-reducing Winograd transform while maintaining accuracy. Cadence's Paul McLellan checks out some of the biggest machine learning systems from Nvidia, Google, and Cerebras that were presented at the recent Hot Chips. Mentor's Robin Bornof... » read more

Zeroing In On Biological Computing
By Katherine Derbyshire - 20 Aug, 2020 - Comments: 0

Artificial spiking neural networks need to replicate both excitatory and inhibitory biological neurons in order to emulate the neural activation patterns seen in biological brains. Doing this with CMOS-based designs is challenging because of the large circuit footprint required. However, researchers at HP Labs observed that one biologically plausible model, the Hodgkins-Huxley model, is math... » read more

Spiking Neural Networks: Research Projects or Commercial Products?
By Bryon Moyer - 18 May, 2020 - Comments: 2

Spiking neural networks (SNNs) often are touted as a way to get close to the power efficiency of the brain, but there is widespread confusion about what exactly that means. In fact, there is disagreement about how the brain actually works. Some SNN implementations are less brain-like than others. Depending on whom you talk to, SNNs are either a long way away or close to commercialization. Th... » read more

Week In Review: Auto, Security, Pervasive Computing

CMOS-compatible laser Researchers at Forschungszentrum Jülich, Center for Nanoscience and Nanotechnology (C2N), STMicroelectronics, and CEA-Leti Grenoble developed a CMOS-compatible laser for optical data transfer. Comprised of germanium and tin, the efficiency is comparable with conventional GaAs semiconductor lasers on Si. Optical communications provide much higher data rates, and are be... » read more

Scaling Up Compute-In-Memory Accelerators
By Katherine Derbyshire - 19 Mar, 2020 - Comments: 3

Researchers are zeroing in on new architectures to boost performance by limiting the movement of data in a device, but this is proving to be much harder than it appears. The argument for memory-based computation is familiar by now. Many important computational workloads involve repetitive operations on large datasets. Moving data from memory to the processing unit and back — the so-called ... » read more

Week In Review: Design, Low Power
By Jesse Allen - 13 Mar, 2020 - Comments: 0

Tools & IP Synopsys revealed DSO.ai (Design Space Optimization AI), an autonomous AI application that searches for optimization targets in very large solution spaces of chip design, inspired by the process of DeepMind's game-playing AlphaZero. DSO.ai engines ingest large data streams generated by chip design tools and use them to explore search spaces, observing how a design evolves over t... » read more

Imec-Leti alliance At the recent IEEE International Electron Devices Meeting (IEDM), Imec and Leti announced plans to collaborate in select areas. The two R&D organizations plan to collaborate in two areas—artificial intelligence (AI) and quantum computing. Imec and Leti have been separately working on AI technologies based on various next-generation memory architectures. Both entitie... » read more

Week In Review: Manufacturing, Test
By Mark LaPedus - 22 Nov, 2019 - Comments: 0

Chipmakers For some time, Intel has experienced supply constraints and shortages for its 14nm chip products. Apparently, the company is still having issues with both 14nm and 10nm. “Despite our best efforts, we have not yet resolved this challenge,” according to a statement from Michelle Johnston Holthaus, executive vice president and general manager of the Sales, Marketing and Communicati... » read more
