Semiconductor Engineering: Spiking Neural Networks: Research Projects or Commercial Products?

Spiking Neural Networks: Research Projects or Commercial Products?

May 18th, 2020 - By Byron Moyer

Opinions differ widely, but in this space that isn't unusual.
 
SNN neurons typically are implemented in one of two ways. The approaches are motivated by analog implementations, although they can be abstracted into digital equivalents.  Arteris IP   fellow and chief architect Michael Frank refers to this as “emulation.” He points to several challenges for an analog implementation: “With analog, you would need to customize the model to the specific chip for inference. No two transistors are the same. And at 7 nm, you can’t do analog.”

Ed Sperling interviews Kurt Shuler at Arteris IP headquarters about the differences between CXL and CCIX.

Arteris IP’s Kurt Shuler talks about how these two standards differ, which one works best where, and what each was designed for.

The Race To Multi-Domain SoCs

February 7th,  2019 - By Ed Sperling

K. Charles Janac, president and CEO of Arteris IP, sat
down with Semiconductor Engineering to discuss the impact of automotive and AI on chip design. What follows are excerpts of that conversation.

SE: What do you see as the biggest changes over the next 12 to 24 months?
Janac: There are segments of the semiconductor market that are shrinking, such as DTV and simple IoT. Others are going through an investment phase, including automotive, AI/machine learning and China. You really want to be focused on those segments. 

SE: So does IP that’s being developed today look radically different than it did five years ago?
Janac:
Yes, everything is getting amazingly complex. What people are building right now are multi-domain SoCs. The CPU, which used to do all the work, does relatively less work. There are accelerators for vision and data analysis outside of the CPU subsystem. There are machine learning sections, some general-purpose, some very specific, all on-chip. There is a memory subsystem with very high-bandwidth memory and low latency. There also is functional safety. You need tremendous performance because a car is a supercomputer on wheels. The car has to be very efficient, because you need to deliver that compute power without water cooling. Power management becomes very sophisticated. And then there are functional safety and security subsystems to keep these safe from environmental and man-made issues.

SE: Where does the network on chip (NoC) fit into all of this?
Janac: All data goes through the NoC of the chip. There are opportunities for generating value from that. But the increase in complexity is increasing the number and sophistication of the interconnect parts of the chip. Before, you may have had networks on chip. Now you may have 20 or 30.

Semiconductor Engineering: ISO 26262:2018, 2nd Edition: What Changes?

 Arteris IP's Kurt Shuler, vice president of marketing, delivers a recent update for the ISO 26262 standard in this blog in Semiconductor Engineering;

ISO 26262:2018, 2nd Edition: What changes?

February 7th,  2019 - By Kurt Shuler

The safety standard is now clearer for IP-based designs and those happening across multiple companies.

If you’re involved somehow in design for automotive electronics, you probably have more than a cursory understanding of the ISO 26262 standard. What your organization is working from is most likely the 2011 definition. The most recent update is formally known as ISO 26262:2018, less formally as ISO 26262 2nd Edition.

Standards should evolve, but what changed and why? I’ve been a member of the ISO 26262 working group for many years, and particularly involved in how it should be interpreted for IP, and I’ve got to tell you, I have struggled. 

From my perspective, it was originally written around an implicit expectation that chips are built from scratch entirely within one organization, and this is a dated assumption. There was also not enough guidance for IP-based design or design distributed across multiple companies or sites. The workaround for an IP supplier has been to use the Safety Element out of Context (SEooC) mechanism. But this depends heavily on human interpretation, by the component vendor on what may be relevant to the integrator and vice-versa, with little guidance from the 2011 version of the standard. I complained (whined?) quite a bit to the committee about these problems and they eventually invited me to the working group. I wasn’t the only one confused and other people joined, and we seem to have had an impact; our efforts have resulted in a lot more clarification, organization and practical examples in the latest standard. I think the new Part 11 of the updated standard provides a lot more detail and useful examples for us in the semiconductor and semiconductor IP industry.
