Solving Multi-Core Design Challenges With Safety Support

The key challenges in developing multi-core ASICs include managing complexity, power optimization, inter-core communication, synchronization, verification, testing, and performance optimization while ensuring scalability, reliability, and integration ease.

Ncore™ solves these challenges with a production-proven, highly configurable, and efficient coherent NoC interconnect IP solution that works with multiple protocols and any processors including Arm and RISC-V. Ncore offers unique value by being engineered to support ISO 26262 designs that, once certified, will ensure reliable operation in safety-critical applications with functional safety compliance.

The combined use of Ncore IP and FlexNoC IP in an ASIC design delivers unparalleled performance optimization, scalability, and system integration, enabling robust cache coherence, efficient communication, and flexibility, leading to market differentiation and accelerated time-to-market.

The Only Multi-Protocol AMBA CHI-B, CHI-E and ACE Cache Coherent NoC

Empowers SoC developers to create high-performance coherent SoC

Scalable

Ncore provides a high-bandwidth, low-latency interconnect fabric for efficient communication between different components of an SoC, offering scalable performance and power efficiency from small embedded systems to large multi-billion transistor designs.

Configurable

Multi-protocol coherency gives choice and reuse for legacy and future IP support. CHI-E, CHI-B, and ACE coherent as well as ACE-Lite IO coherent agent interfaces allow multiple initiator IPs to be connected to the same Ncore. Ncore also enables AXI non-coherent agents to act as IO coherent agents.

Safe

ISO certified by an external assessor to ensure Ncore readiness for use in ISO 26262-compliant chips from ASIL B to ASIL D requirements provided by Safety and Reliability product options.

Customers

We are happy to share that we are partnering with Arteris to use Ncore and FlexNoC IP in our next-generation product. The combination of performance and features made it a great choice for both our AI chips and our high-performance RISC-V CPUs. The Arteris team and IP solved our on-chip network problems so we can focus on building our next-generation AI and RISC-V CPU products.

Tenstorrent – Ncore

Jim Keller, CEO, Tenstorrent

We chose the Arteris Ncore cache coherent interconnect because of its unique proxy caches and their ability to underpin high-performance, low power, cache coherent clusters of our unique AI accelerators. And with our prior experience using FlexNoC and the FlexNoC FuSa Option for functional safety, we trust Arteris to be the highest performing and safest choice for ISO 26262-compliant NoC IP.
