Arteris FlexGen Opens Up Multi-Die Traffic Management for Non-Coherent Networks

What happened

Arteris has introduced the FlexGen Multi-Die solution, extending multi-die traffic management to non-coherent networks. While the previously introduced Arteris Ncore Multi-Die solution addressed coherent traffic across chiplets, FlexGen Multi-Die now addresses the even more common requirement of non-coherent traffic: by tunneling the NoC protocol through the UCIe link, it automatically extracts QoS management information, carries it as sideband signals, and reconstructs it into the NoC on the other chiplet, making the chiplet-to-chiplet interface transparent and preserving inter-chiplet traffic policy management. Rick Bye, Director of Product Management and Marketing at Arteris, said the solution is very configurable and largely agnostic to the PHY IP a designer uses; Arteris is already working with several companies that have their own PHY IP, most notably AMD, which provided an enthusiastic endorsement, and over time Arteris also expects to qualify this new capability with some commercial UCIe IP options. Additionally, FlexGen Multi-Die can enable more efficient use of UCIe IP: for chiplet pairs where both sides can initiate and be targets (a scenario seen when replicating chiplets each containing an XPU and memory), some AXI-to-UCI bridges require two UCIe ports per chiplet, whereas FlexGen Multi-Die manages that traffic up to bandwidth limitations and is more area, power, and I/O efficient. This is a product technology write-up with no price, capacity, or supply-demand data.
