  • The government of a small but important country has decided that the alphabet needs to be streamline

    The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition

  • MISRA (The Motor Industry Software Reliability Association 汽車工業軟件可靠性聯會) 是位于英國的一個跨國汽車工業協會

    MISRA (The Motor Industry Software Reliability Association 汽車工業軟件可靠性聯會) 是位于英國的一個跨國汽車工業協會,其成員包括了大部分歐美汽車生產商。其核心使命是為汽車工業提供服務和協助,幫助廠方開發安全的、高可靠性的嵌入式軟件。這個組織最出名的成果是所謂的MISRA C Coding Standard,這一標準中包括了127條C語言編碼標準,通常認為,如果能夠完全遵守這些標準,則你的C代碼是易讀、可靠、可移植和易于維護的。最近很多嵌入式開發者都以MISRA C來衡量自己的編碼風格,比如著名的uC/OS-II就得意地宣稱自己99%遵守MISRA標準。而《嵌入式開發雜志》也專門載文號召大家學習。編碼規范通常是一個公司自定的“土政策”,居然有人去做標準,而且還得到廣泛的認可,這不禁引起我強烈的興趣。可惜這份標準的文本需要花錢去買,而且短短幾十頁,要價非常昂貴。MISRA在網上公布了一些文檔,其中有關于MISRA C Coding Standard的Clarification報告,從中間你可以大致猜到MISRA標準本身是什么。

  • This book is a hands-on introduction to the principles and practice of embedded system design usin

    This book is a hands-on introduction to the principles and practice of embedded system design using the PIC microcontroller. Packed with helpful examples and illustrations, it gives an in-depth treatment of microcontroller design, programming in both assembly language and C, and features advanced topics such as networking and real-time operating systems. It is accompanied by a CD-ROM containing copies of all programs and software tools used in the text and a `student version of the C complier Designing Embedded Systems with PIC Microcontrollers: Principles and Applications is ideal for students of electronics, mechatronics and computer engineering. Engineers in industry and informed hobbyists will also find this book a valuable resource when designing and implementing both simple and sophisticated embedded systems using the PIC Microcontroller.

  • The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowled

    The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowledge of the elements of arithmetic as they exist on a computer. That conclusion and this book are the result of a long and frustrating search for information on writing arithmetic routines for real-time embedded systems. With instruction cycle times coming down and clock rates going up, it would seem that speed is not a problem in writing fast routines. In addition, math coprocessors are becoming more popular and less expensive than ever before and are readily available. These factors make arithmetic easier and faster to use and implement. However, for many of you the systems that you are working on do not include the latest chips or the faster processors. Some of the most widely used microcontrollers used today are not Digital Signal Processors (DSP), but simple eight-bit controllers such as the Intel 8051 or 8048 microprocessors.

    This application report describes the use of Timer_A3 to decode RC5 and SIRC TV IR remote control signals. The decoder described in this report is interrupt-driven and operates a background function using specific features the Timer_A3. Only a small portion of the MSP430 CPU?s nonreal-time resources is used. Specific hardware bit-latching capabilities of the Timer_A3 module are used for real-time decoding of the IR data signal, independent and asynchronous to the CPU. CPU activity and power consumption are kept to an absolute minimum level. The Timer_A3 decoder implementation also allows other tasks to occur simultaneously if required. The solutions provided are written specifically for MSP430x11x(1) and MSP430x12x derivatives, but can be adapted to any other MSP430 incorporating Timer_A3. 電視遙控器設計基於MSP430
