Utilize Advanced RPMB for Faster and More Secure UFS 4.0 Authentication

In a 5G world, fast and secure connectivity is important. The JEDEC Universal Flash Storage (UFS) version 4.0 helps to ensure this is possible in our everyday devices. As an added security element, a Replay Protected Memory Block (RPMB) is included in UFS devices as a means to store encrypted data securely, only accessible by authentication.

Attention Gamers! HDMI 2.1a Introduces Source Based Tone Mapping (SBTM)

HDMI (High-Definition Multimedia Interface) is the most popular medium for transporting both audio and video information between two digital devices. In the past two decades, HDMI technology has evolved from HDMI 1.0 to HDMI 2.0. In 2017 HDMI 2.1 introduced enhanced gaming and media features such as Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) to eliminate lag, stutter, and tearing, adding smoothness to the gaming and video experience. Recently the HDMI Forum has announced a new version, HDMI2.1a, that brings a standout gamer-friendly feature, Source-Based Tone Mapping (SBTM).

Reduced Blanking: The Way to Low Power, High Resolution Displays

With the release of HDMI 2.1, higher video resolutions and refresh rates including 8K@60Hz and 4K@120Hz are a reality. In a previous blog, 10K Resolution at 120Hz Display: A Reality Today with DSC 1.2 in HDMI 2.1, we explained how HDMI 2.1 can support resolutions and refresh rates of the order 4K@240Hz, 8K@120Hz and 10K@120Hz with display stream compression (DSC). With increased resolution you get finer details and with higher refresh rate the moving content feels smoother. But it also means more pixel information and thus higher data transmission rate, higher bandwidth, and higher power consumption. What if there is a way to reduce the transmission rate while keeping the resolution and refresh rate intact? The answer lies in the reduced blanking feature in which the blanking region of a frame is reduced significantly.

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.

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?
