Nuvoton Expertise Company Japan (NTCJ) will begin a sequence manufacturing of automotive
HMI show IC “Gerda”, 4th era, that are 3 sorts (Gerda-4M/ Gerda-4L/ Gerda-4C).
This lineup options picture processing know-how, safety, and show security features for the assorted HMI units that are progressing beneath expectation to help the upper stage of security requirement. And it contributes to realizing the HMI options which improve car security and luxury.
Achievements:
- By producing the excessive visibility of inside show utilities equivalent to digital mirrors, AR-HUD, and cluster meters, “Gerda” assists consolation and fatigue-resistant protected driving by system.
- By high-speed and huge capability reminiscence in-built “Gerda” permits prospects to develop the high-functional HMI techniques with superior show functionality with out exterior reminiscence at affordable price in system.
- “Gerda” options OTA (Over-The-Air software program updating) and safe boot features, and contributes to the protected and luxury techniques by mitigating the dangers of on-vehicle cyber safety and supporting the useful security stage ASIL-B.
Options:
- Refined visibility and luxury of HMI tools is realized with distinctive picture processing engine.
Our video processing know-how is good for digital mirrors, AR-HUDs, and cluster meters, which have gotten broadly unfold because of digitization of kit put in in vehicles, to create a protected and comfy driving setting.
– Options for digital mirrors
The problem with standard e-mirrors had points with diminished visibility, particularly in night time time digicam photographs, because of glare attributable to headlight mild and white blown out/blacked out because of huge hole in brightness.
With Gerda-4M, it’s doable to enhance the visibility by adjusting the image distinction regionally, in response to the brightness distribution by space (“native distinction” operate), could be achieved with low-latency processing of 1 body.
– Options for AR-HUD
It’s important with AR-HUD that the show naturally saved proven within the driver’s eyesight by harmonizing the displayed contents to the windshield form.
For this, displaying picture must be projected in low latency, and versatile deformed to suit the windshield. Picture warping engine permits free deformation to suit the display screen at decrease latency than 1 body. And it helps “twin projection HUD” with single chip, which each 2 photographs are projected in close to and much focuses.
– Options for cluster meters
It’s important with cluster-meter that a number of helping info is carried out to drivers precisely and intuitively. And its design must flexibly match the inside. Nuvoton’s Gerda has 2.5D GFX engine which permits prospects to design the display screen with cubic results like depth and shades added to the design by 2D objects. It gives the show with larger visibility and contributes to the correct choice of drivers. And by mixture with the picture compression engine, displaying photographs at as excessive decision as WXGA@60FPS which allows the higher-grade cockpit design.
- Multi-functional HMI system is realized at diminished system price with built-in excessive velocity/ massive measurement reminiscence.
Basically, building of high-performance HMI techniques requires exterior reminiscences the system. Nuvoton’s lineup of Gen.4 is embedded with the reminiscence of excessive velocity and huge capability, which makes exterior reminiscence pointless, and contributes to scale back the part counts and system price. And Gerda-4L has built-in the devoted picture compression engine which allows the real-time processing at half reminiscence utilization than regular use, and it realizes excessive decision picture show as WXGA@60FPS solely with the built-in reminiscence.
- Supporting Purposeful Security ASIL-B, and contributing to the chance mitigation of car cyber safety
Gen.4 Gerda options the show security features as video sign monitoring, alert show monitoring and so forth., and contributes to comprehend the system of Purposeful Security ASIL-B by supporting the features as fail-safe, real-time monitoring. And the built-in HSM which helps EVITA-Full achieves the software program replace by way of community (OTA) and safe boot, which permits solely trusted software program in addition up. It helps to mitigate the chance of car cyber safety.
NTCJ developed the three sorts of 4th era of HMI show IC “Gerda” sequence which is supplied with a variety of picture processing applied sciences and superior safety features and has began its mass manufacturing.
