Link Acceleration Unit
Comprehensive Portfolio of Device-Specific PCIe 7.0-CXL 4.0 IP
Overview
Panmnesia's Link Acceleration Unit (LAU) IP is a purpose-built hardware block that accelerates device-specific, end-to-end communication over CXL. The IP significantly reduces time-to-market for diverse types of hardware design such as memory expander devices (CXL type 3), accelerators (CXL type 1/2), and CPUs.

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.
