Synopsys IDE Security IP Module for CXL 3.x

The Compute Express Link (CXL) interface protocol enables low-latency data communication between system-on-chip (SoC) and general-purpose accelerators, memory expanders, and smart I/O devices requiring high performance, heterogeneous computing for data-intensive workloads.

The Synopsys CXL 3.x Integrity and Data Encryption (IDE) Security IP Module provides confidentiality, integrity, and replay protection for flow control units (FLITs) in the case of CXL.cache and CXL.mem protocols, and for FLITs and Transaction Layer Packets (TLP) in the case of

The Security Module implements the IDE specification as defined for CXL 3.x which also references PCI Express 6.x IDE specification for the protocol. The Synopsys CXL 3.x IDE Security Module integrates seamlessly with the Synopsys CXL controllers to accelerate SoC integration.

The Synopsys CXL 3.x IDE Security Module provides full-duplex .cache/.mem/.io support with efficient encryption/decryption and authentication of FLITs and TLPs, based on optimized low latency AES-GCM cryptographic cores, that are specially developed for optimal area, performance, and latency implementations.
