Benefits

Hardware-Managed Cache Coherency

Manage cache coherency without software intervention. LAU IP supports hardware-automated handling of cache coherency features, such as back invalidation, for diverse types of devices.

Device-Specific Hardware Optimization

Minimize communication latency and deliver fast, deterministic responsiveness in latency-critical workloads. LAU IP offloads device-specific processes into hardware, enabling real-time execution when every nanosecond counts.

Best-In-Class Latency & Power Consumption

Achieve exceptional latency and power efficiency with a purpose-built, optimized architecture. Maximize performance-per-watt for power-constrained and performance-critical designs.

CXL Topology-Aware and Expander-Driven Prefetching: Unlocking SSD Performance

This paper presents an expander-driven CXL prefetcher, ExPAND, designed to offload primary LLC prefetching tasks from the host CPU to CXL-SSDs, addressing CPU design area constraints. Implemented within CXL-SSDs, ExPAND employs a heterogeneous machine learning algorithm for address prediction, enabling data prefetching across multiple expander accesses.

Synopsys continues to lead innovation with the industry’s first commercially available CXL 4.0 Verification IP (VIP). This comprehensive solution supports the full 128 GT/s data rate, IO throttling, and streamlined port negotiation, equipping designers to validate and optimize their products for the future.

Powering Up Efficiency: A Deep Dive into CXL L0p and its Verification

Compute Express Link (CXL) is revolutionizing data center architecture, with power management emerging as a key area of innovation. Among its power-saving mechanisms, the L0p (Low Power) state plays a pivotal role in reducing energy consumption during periods of low link activity.

Demystifying CXL Memory Interleaving and HDM Decoder Configuration

Memory interleaving is a technique that distributes memory addresses across multiple memory devices or channels. Instead of storing data sequentially in one device, the system alternates between devices at a fixed granularity. It could help improve bandwidth, reduce latency, and enhance scalability. In the context of Compute Express Link (CXL), memory interleaving is facilitated by the HDM (Host-Managed Device Memory) Decoder.
