SoC interconnect IP enables highly scalable neural network systems with integrated hardware functional safety features for ISO 26262 ASIL D compliance

Linley Autonomous Hardware Conference 2017, SANTA CLARA, Calif. — April 6, 2017 — ArterisIP, the innovative supplier of silicon-proven commercial system-on-chip (SoC) interconnect IP, today announced the Ncore 2.0 Cache Coherent Interconnect IP and the optional Ncore Resilience Package to accelerate and enhance the creation of next-generation designs for autonomous driving systems and advanced driver assistance systems (ADAS).

We are very impressed with the new ArterisIP Ncore interconnect IP technology. ArterisIP Ncore 2.0 interconnect IP offers even higher scalability along with the Coherent Memory Cache, which reduces DRAM accesses while maintaining area efficiency.

Mr. Yu Li, Vice President, Sanechips (Subsidiary of ZTE)

Ncore is a distributed heterogeneous cache coherent interconnect that enables SoC design teams to easily integrate custom processing elements using embedded low latency proxy caches (also called “I/O caches”). In neural network machine learning SoCs where workloads are typically partitioned onto different processing elements, low latency proxy caches offer a more hardware- and software-efficient way of communicating between all the different elements than fixed internal SRAMs or scratchpad memories. These types of architectures are at the core of autonomous driving systems.

Ncore 2.0 offers new capabilities:

  • Ncore Resilience Package (optional) – Adds hardware data protection and intelligent unit duplication to detect and correct system faults required to achieve automotive ISO 26262 ASIL D compliance
    • Includes a functional safety controller with advanced Built-In Self-Test (BIST) as well as Failure Modes, Effects and Diagnostic Analysis (FMEDA) and documentation.
  • Coherent Memory Cache – The configurable coherent memory cache achieves the benefits of a traditional Last Level Cache (LLC) while consuming less die area and offering more flexibility. It integrates with other system caches, serving at as a lower-level cache in the memory hierarchy relative to those caches.
  • Scalability, with up to 16 coherent agents – Ncore 2.0 IP enables larger systems with up to 16 coherent clusters.

“We engineered the Ncore 2.0 cache coherent interconnect and the accompanying Ncore Resilience Package based on feedback from our customers, who are creating the world’s most efficient machine learning systems that will power the future of autonomous driving,” said K. Charles Janac, President and CEO of ArterisIP. “Our IP was specifically created for autonomous hardware SoC designers, enabling them to simultaneously meet the competing needs of design complexity and functional safety.”

“We are very impressed with the new ArterisIP Ncore interconnect IP technology,” said Mr. Yu Li, VP at Sanechips (Subsidiary of ZTE). “ArterisIP Ncore 2.0 interconnect IP offers even higher scalability along with the Coherent Memory Cache, which reduces DRAM accesses while maintaining area efficiency.”

The Linley Group:

“Designers of machine-learning SoCs must integrate heterogeneous processor cores and accelerators into a complex system that can handle the high data bandwidth and low latency required for such applications,” said Mike Demler, senior analyst for the Linley Group. “ArterisIP’s new Ncore 2.0 interconnect IP with resiliency features addresses these issues by enabling designers to implement heterogeneous cache-coherent machine-learning architectures for applications such as the rapidly developing autonomous-vehicle market.”


“Implementing functional safety mechanisms in SoC interconnect hardware is imperative for highly complex machine learning SoCs,” said Andrea Bondavalli, Professor of Computer Science and head of the Resilient Computing Lab at the University of Florence, and scientific advisor to ResilTech, a leading functional safety consultancy, “Doing so simplifies software development and maintenance while freeing scarce processing resources to perform functional work rather than safety checking.”
