UCIe Die-to-Die Chiplet Controller
The UCIe Controller IP is a configurable and customizable UCIe 1.1 compliant die-to-die controller.
Overview
The UCIe Controller IP is a highly configurable and customizable UCIe 1.1 compliant die-to-die controller. It extends on-chip AXI interconnections to multi-die connections, providing an advanced solution for multi-die connectivity across various applications. The controller uses flits, which are flow control units that are both reliable and latency-optimized. In addition, OUC ensures that the receiver buffer does not overflow at the receiver end. With its well-defined AXI packet structure, the OUC seamlessly matches AXI parameters with its link partner, ensuring smooth format matching and communication even with different AXI parameters. OUC matches the protocol using padding and cropping with default operation rules defined in AXI.
This UCIe chiplet brings highly customizable, package-level integration with die-to-die interconnect and protocol connections, creating an interoperable, multi-vendor ecosystem, and establishing a new industry standard for universal interconnect at the package level.
