1. Overview
This article will introduce how to use Intel Atom series CPUs to build a high-performance, upgradeable hardware platform that not only meets basic vehicle requirements such as shock resistance, wide temperature, low power consumption, stability, and safety, but also supports Microsoft Windons series operating systems and wireless Broadband Internet access. Service providers can rely on existing mature software and Internet platforms to provide high-end users with real-time road condition information, intelligent navigation, vehicle failure monitoring, wireless communication, mobile office, security warning, anti-theft, voice control, centralized scheduling, and assistance High value-added applications such as driving. Take advantage of the growing trend of faster and more convenient network communication and information processing, and work with communication operators and various service providers to develop a wider application market for in-vehicle computers.
Second, the use of modular technology to quickly build an in-vehicle computer platform For customers who are first exposed to x86 hardware platforms, they generally encounter the following major obstacles:
1. Due to the higher transmission rate of the signal line, the hardware wiring is more complicated.
2. The software system adopts BIOS + operating system startup mode, and the initial development investment is relatively high.
3. During mass production, a large-scale stability test is required and the investment is high.
4. x86 development is more difficult and has a longer period.
For this reason, for designers who already have rich experience in automotive electronics design, we recommend that modular design be used for product design in the early stage. The core concept is: the core part of the CPU with high technology content, complex production process and relatively fixed structure adopts mature CPU modules; while related to customer needs, application functions that vary greatly, such as FM, CMMB, GPS, etc On the module backplane. In this way, designers can rely on existing product design experience to quickly launch on-board computer products supporting various x86 platforms.
Advantages of modular design:
Greatly reduce development risk and cycle time
Greatly reduce investment in development funds
Quickly and freely build personalized systems
Easily extend the product line
Speed ​​up the marketing process
3. Successful case analysis
The ENC-Z510 CPU module developed and produced by Inkvision adopts Intel's Atom CPU Z510PT and US15WPT bridge designed for the embedded market. It has high performance, low power consumption, supports industrial temperature and scalability It has been adopted by many manufacturers due to its strong performance and long time for mass production, and has completed a number of in-vehicle computer products.
Introduction to the CPU platform
The Intel® Menlow platform is composed of the Atom ™ Z5XX series code-named Silverthorn and the US15W bridge piece of the north-south bridge code-named Poulsbo.
