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?

Faster closure, simulation acceleration to emulation

It’s a longstanding cliché, but it is true that verification is a marathon. An integrated verification platform accompanied by a systematic verification methodology are the building blocks to manage the verification complexity of modern system-on-chip (SoC) designs. High performance simulation environment is the foundation however it is not enough to reach to the verification closure that requires regressing hardware in conjunction to real application scenarios and software.

MIPI CSI-2 v3.0 is here! – The industry’s First Comprehensive Solution for 5G, Imaging, Surveillance and Automotive

Smartphones have become a one-man army by incorporating fancy features like biometric authentication, telemedicine, heartrate monitoring. With increasing market demands and requirements for higher image resolutions, MIPI CSI-2 (Camera Serial Interface) has evolved tenfold from where it first started. MIPI CSI-2 v2.0 is designed for use in smartphones, Internet of Things (IoT) devices, wearables, medical devices, augmented and virtual reality. MIPI Board recently adopted MIPI CSI-2 Specification v3.0 and approved associated CTS documents, refer https://members.mipi.org/wg/All-members/document/download/79549.
