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.

Understanding Color Space Conversions in Display

Color space is a very powerful tool that comes in handy when capturing, transmitting and reproducing color back to the human eye. Systems such as cameras, GPUs, transmission cables (HDMI/DP), and monitors use color space metrics to preserve and transform color. This technology helps map real colors to the color model’s discrete values.

8K Ultra HD: A Giant Leap for High Definition Televisions

Lately television lovers across the world have an even better reason to be glued to the small screens, as 8K Ultra HD TVs have made their way to the market. The HDMI forums most recently released specification, v2.1, explains “higher video resolutions support a range of high resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail…”   Most of us are familiar with the word “resolution”, but do we really know this term well?
