Graphics SoC for HMI and View Systems

This catalog introduces the MB86R20 series of Third-Generation Graphics SoCs which have high performance CPU/GPU, six video inputs, and three display output functions. This document discusses the characteristics of the MB86R20 series as well as the different applications it can be used. It also discusses Integrated HMI systems and the tools used like CGI Studio.

Introduction

In order to increase the environmental friendliness, safety, relief and comfort of automobiles, there is an increasing need for “Integrated HMI (Human – Machine Interface) Systems” that are windows of information linking together people, automobiles and the world, and the need is also increasing for “360° Wraparound View Systems with Recognition Functions” that warn without fail about dangers surrounding the vehicle in a three-dimensional manner. The “MB86R20 series” third-generation graphics SoC, compared to the second-generation graphics SoC of the “MB86R10 series”, has its CPU and GPU performances increased by 2 times and 5 times, respectively, and also has 6 video inputs and 3 display output functions all available at the same time. Further, systems with one-stop procurement of all necessary items and with lesser number of man-hours can be developed because the necessary software is also provided along with the chips.

Tendency of Integrated HMI

In order to experience driving that is environment-friendly, safe, relieved, and also comfortable, the amount of information linking people, automobiles, and the outside increases dramatically. Now-a-days, such information spans various aspects such as battery information of electric vehicles, vehicle fault diagnosis information, image information from cameras, warning information, navigation information, smart-phone-linked information, and cloud-linked information and so on.

Until now individual display control was being made of such information using the center display, cluster display, head-up display etc. (Figure 1). However, in order to transfer information in real time and in an easy-to-understand manner between the driver and the vehicle, it is necessary to aggregate all such information in one location and to carry out centralized control of how the information is portrayed to match with the driving situation. This is done by an integrated HMI system, and this trend is considered to accelerate as the harmony among people, automobiles, and the environment increases.

The MB86R20 series has a high performance CPU/GPU, 6 video inputs, and 3 display output functions available all at the same time, aggregates video information from various sources such as a system of cameras, head units, etc., and carries out appropriate display control of the center display, cluster display, head-up display, etc. to suit the driving situation.(Figure 2)

Towards Further Safety and Relief

In a 360° wraparound view system, the entire surroundings of the vehichle can be checked clearly and also from any viewpoint by 3-D processing of the images from four cameras installed at the front, rear, left, and right of the vehicle. Systems using the MB86R10 series devices, which are second-generation SoC, have already been introduced in the market and are starting to spread worldwide(Figure 3)

The MB86R10 series can accept not only analog cameras but also mega-pixel digital cameras, whereby the surrounding of the vehicle can be portrayed as very clear images. Along with the proliferation of this system, the demand is not only for the ability to visually verify the surroundings of the vehicle but also fornew functions that reduce items overlooked by the driver. The third-generation SoC of the MB86R20 series has much higher performance CPU/GPU, and it has been possible to realize both checking of the surroundings from any viewpoint and reduction of oversight by the driver due to object recognition. In addition, since 6 camera images can be handled at the same time, the concerned scene can be enlarge and the degree of freedom of portraying the 3-D image has been increased.
