數(shù)據(jù)異常處理。The main source file is "dabort.s": with suItable -PreDefines or
a corresponding "options-setting" file, it assembles to the data
abort veneer. This is described in detail in the documentation.
The "dabort.h" file contains definitions of some constants used
in the data abort veneer s interface to the rest of the system
- again, this is described in the documentation.
The "option.s" file is an example "options-setting" file.
This document specifies a subset of the C programming language which is intended to be suItable
for embedded automotive systems up to and including safety integrity level 3 (as defined in the
MISRA Guidelines). It contains a list of rules concerning the use of the C programming language
together with justifications and examples.

針對(duì)目前汽車(chē)追尾事件頻發(fā)問(wèn)題,提出一種防汽車(chē)車(chē)前和車(chē)后追尾的安全裝置設(shè)計(jì)。該設(shè)計(jì)以高性能、低功耗的8位AVR微處理器ATmega8L為核心,結(jié)合霍爾式車(chē)速傳感器、激光雷達(dá)測(cè)距裝置和MMA7260QT加速度傳感器,能夠兼顧車(chē)前和車(chē)后,摒棄以往設(shè)計(jì)中只考慮車(chē)前或車(chē)后單一性缺點(diǎn),尤其適用于高速、夜晚或新手行車(chē)。
Abstract:
Aiming at the high frequency of vehicle rear-end collision,a safe device design of anti-vehicle rear-end collision is presented.In the design,the high-performance,low-power8-bit AVR microprocessor ATmega8L is utilized as a core combined with Hall-type speed sensor,laser-radar ranging devices and the acceleration sensor MMA7260QT.The design considers both the front and back of a car,and overcomes the drawbacks of former designs in which only the front or the back of the car is considered,so it is especially suItable for high-speed,night or the beginner’s driving.
Bootloader是微處理器上電時(shí)運(yùn)行的第一段代碼,它可以通過(guò)通信接口實(shí)現(xiàn)對(duì)微處理器內(nèi)部應(yīng)用程序的更新升級(jí),為網(wǎng)絡(luò)化嵌入式產(chǎn)品的應(yīng)用程序升級(jí)帶來(lái)極大的便利。由于目前沒(méi)有統(tǒng)一嵌入式系統(tǒng)的Bootloader。基于NEC 78K0系列單片機(jī)自編程原理,設(shè)計(jì)出一個(gè)適用于78K0/Fx2系列單片機(jī)的Bootloader,并能夠通過(guò)單片機(jī)串口在線(xiàn)升級(jí)應(yīng)用程序。
Abstract:
Bootloader is the first piece of code executed after microprocessor startup. It makes the embedded product’s firmware update conveniently through communication interface. However, no unified bootloader is available for all kinds of microprocessor products. Based on the principle of self-programming NEC 78K0s’ series, a useful Bootloader which is suItable for 78K0/Fx2s’ series MCU is designed,the design can update the application through serial ports.
