Nuvoton Launches Fourth Generation of the Gerda Series

Nuvoton Technology Corporation Japan (NTCJ) has officially unveiled its fourth-generation automotive HMI (Human-Machine Interface) display integrated circuit (IC) series known as Gerda (TM). This new lineup is set to revolutionize the automotive sector with three variants: Gerda-4M, Gerda-4L, and Gerda-4C. By focusing on advanced image-processing technologies and enhanced display safety functions, Nuvoton aims to meet the increasing safety demands of modern driving environments.

Advanced Image-Processing Technologies

One of the standout features of the Gerda series is its superior image-processing engine, designed to significantly enhance visibility and user comfort. For instance, the Gerda-4M variant addresses common issues experienced by electronic mirrors, such as glare from bright lights and visibility loss in high-contrast conditions—particularly at night. It employs a local contrast function that adjusts screen contrast dynamically based on luminance distribution across different areas, resulting in unparalleled clarity and comfort. Furthermore, its low-latency processing speed ensures that display improvements occur in real time, making it a reliable choice for drivers.

The Gerda series also introduces innovations aimed at Augmented Reality Head-Up Displays (AR-HUDs). These displays require precise alignment with both the windshield curvature and the driver’s line of sight. The image-warping engine within Gerda (TM) allows for low-latency image deformation, enabling seamless projection onto the windshield. This technology supports dual projection, allowing for images to be focused at varied distances with just a single chip.

For cluster meters, the Gerda (TM) series boasts a 2.5D graphics engine (GFX). This engine simulates 3D effects using 2D elements, enhancing depth perception and overall readability, which can lead to quicker, more accurate decision-making by drivers. When coupled with an image compression engine, the system can deliver high-resolution outputs of WXGA at 60 frames per second, offering a modern dashboard experience that is both engaging and informative.

Streamlined Performance with Integrated Technologies

High-performance HMI solutions typically rely on external memory, which can complicate designs and increase costs. However, the Gerda (TM) Gen-4 series integrates high-speed, large-capacity memory directly into the units, minimizing the need for external components. The Gerda-4L variant prominently features a dedicated image compression engine, enabling the display of high-resolution images using only half the memory, thus achieving unparalleled efficiency.

Display Safety Functions and Enhanced Security

In addition to advanced image processing, the Gen-4 Gerda series incorporates several essential display safety functions, such as video signal monitoring and alert display monitoring. These features not only ensure compliance with ISO26262 ASIL-B requirements but also facilitate safe, real-time monitoring of HMI systems. Nuvoton emphasizes vehicle cybersecurity by integrating a Hardware Security Module (HSM) compliant with EVITA-Full. This module supports secure over-the-air (OTA) software updates and trusted boot capabilities, protecting vehicles from cybersecurity threats.

NTCJ has gained recognition as the first Japanese company certified under the TUV process of ISO/SAE 21434, demonstrating a commitment to enhancing cybersecurity across the supply chain and bolstering overall reliability.
