Compute Express Link™ (CXL™) emerges as an innovative and high-speed Cache-Coherent Interconnect that aims to bolster data transmission and processing performance, especially for memory-intensive workloads like artificial intelligence (AI) and Big Data. The CXL Consortium’s compliance testing holds paramount importance in verifying the adherence of diverse devices within the CXL ecosystem, including CPUs, CXL-based devices, and accelerators, to the stringent CXL specifications. This testing also serves as a prerequisite for ensuring seamless interoperability among these devices.

Montage’s trailblazing journey began in May 2022 when it introduced the world’s first CXL™ Memory eXpander Controller (MXC). This innovative product facilitates a high-bandwidth, low-latency interconnect between the CPU and CXL-based devices, effectively enabling memory expansion. As a result, it translates to elevated system performance and reduced Total Cost Ownership (TCO) within data centers.
