Accessing Memory Mapped Registers in CXL 2.0 Devices

CXL 1.1 and CXL 2.0 specification differ in the way memory mapped registers are placed and accessed. The CXL 1.1 specification places memory mapped registers in RCRB (Root Complex Register Block) while the CXL 2.0 specification links memory mapped registers in BAR (Base address ranges) of the device. In this blog we will focus on how to access CXL 2.0 specification memory mapped registers.

Hands-on Verification Tutorials Hosted on AWS Environment

Verification consumes most of the compute resources in a typical data center for a semiconductor design company. Simulation comprises one of the largest, if not the largest, workloads in this mix. To maximize the likelihood of first silicon success, development teams often increase the volume of simulation jobs they run in preparation for tape-out. However, this effort is often limited by the compute resources that customers can bring to bear on the task.

Accelerate SoC Verification, Experts available

SoC designs are growing more complex, not just by the sheer number of transistors that can be packed into one design, but the emergence of different interconnect methods you must use to connect chip internals and to connect to the outside world. Becoming an expert on each of the interconnect protocols is not going to shorten the verification schedules, reduce design productivity and expose design bugs that might only be found when used by the end consumer.

CXL – The Latest Specification in Secured Network Traffic

Welcome to the wonderful and cryptic world of secured traffic with CXL being the latest specification to adopt it. CXL2.0 specification introduces integrity & data encryption (IDE) schematics for both CXL.io & CXL.cachemem protocols. CXL.io pathway uses PCIe specification defined IDE, while CXL.cachemem related updates are introduced in CXL2.0 specifications. In this blog we’ll provide a broad overview of what a secure setup looks like and the strategies adopted by CXL for the same.

De-mystifying CXL: An overview

As Data Center and Artificial Intelligence applications take center stage , last few years have seen the advent of various high bandwidth interconnect technologies. Compute Express Link (CXL), is an aspiring new interconnect technology for high bandwidth devices such as accelerators with memory, high density compute cards, and GPU comprised accelerators. The specification is defined by CXL Consortium https://www.computeexpresslink.org/. Synopsys has developed a comprehensive ­­CXL verification subsystem, being already used by Early Adopters planning to release their first CXL applications. CXL verification subsystem leverages industry popular Synopsys PCI Express Verification IP. Synopsys recently introduced Industry’s first CXL IP solution. For more details refer Synopsys Delivers Industry’s First Compute Express Link (CXL) IP Solution for Breakthrough Performance in Data-Intensive SoCs.
