PanEndpoint

Enabling Custom Hardware Acceleration Over a Cache-Coherent Link

High Fan-Out CXL Switch
Solution Overview

Series of CXL 3.x Endpoint Silicon Chips, Customizable to Your Needs

We offer a customizable CXL 3.x endpoint SoC design service, enabling partners to build their own high-performance hardware tailored to AI, HPC, and cloud workloads. Our PanEndpoint design platform provides a foundation for building CXL 3.x-compliant Type 1/2/3 endpoint chips. It supports direct, low-latency, cache-coherent communication between devices and is fully customizable—allowing you to integrate proprietary logic or modify existing modules to meet your system requirements. Rather than selling off-the-shelf chips, we co-develop silicon solutions with customers to optimize performance and achieve system integration goals. PanEndpoint suits various devices such as memory-attached endpoints, large-capacity storage with persistent media, and AI accelerators. Backed by our IP portfolio and hands-on services—architecture reviews, RTL tuning, and thorough verification—we help partners reach market faster, stay fully standards-compliant, and deliver the performance demanded by next-generation AI, HPC, and cloud infrastructures.

Key Benefits

Hardware-Managed Cache Coherency

Manage cache coherency without software intervention. Built with our Link Acceleration Unit (LAU) IPs, PanEndpoint supports hardware-automated handling of cache coherency features such as back invalidation.

Proven in an End-to-End System

Reduce interoperability risks with end-to-end-proven endpoints. By leveraging our comprehensive portfolio of CXL IPs, all types of CXL EPs have been validated in full-system configurations encompassing CPUs, switches, and endpoints.

Best-In-Class Latency & Power Consumption

Ensure low latency and low power consumption. PanEndpoint employs our Link Controller IP, boasting two-digit nanosecond roundtrip latency. The optimized architecture also offers the lowest power consumption as an endpoint.
