Newly introduced Arteris FlexGen Multi-Die NoC IP extends non-coherent network-on-chip connectivity across die-to-die links. The expanded multi-die solution is available to early access partners and strategic customers.
The product adds die-to-die controller IP to Arteris FlexGen smart NoC IP so non-coherent connectivity can cross chiplet boundaries. Arteris’s announcement states that FlexGen Multi-Die supports bidirectional transactions over a single UCIe PHY, reducing PHY area, power and I/O requirements by up to 50%, and that it includes virtual-channel link technology and quality-of-service mechanisms for shared die-to-die links. It is positioned for non-coherent AI and HPC architectures and complements Ncore Multi-Die, which remains the cache-coherent product and is not this record. The product page also describes a configurable FLIT-format die-to-die controller for third-party PHYs including UCIe and BoW, up to eight independent receive and transmit virtual channels with credited links, and application domains spanning HPC and AI accelerators for data centers, automotive, consumer and industrial electronics. The expanded Arteris multi-die solution is available today to early access partners and strategic customers. This listing is distinct from FlexNoC already in the catalog.
