This book introduces embedded systems to C and C++ programmers. Topics include testing memory devices, writing and erasing Flash memory, verifying nonvolatile memory contents, controlling on-chip peripherals, device driver design and implementation, optimizing embedded code for size and speed, and making the most of C++ without a performance penalty.

YSS915 (KP2V2) is an LSI for processing Karaoke voice signals. This LSI has an A/D converter (1 channel) for the microphone echo, and a memory for the microphone echo and key control. These features allow achieving the functions needed for the Karaoke system by using only one LSI chip. As for the microphone echoes, many other types of echoes are available in addition to ordinary ones so that YSS915 is applicable to various uses. In addition to these Karaoke programs, YSS915 is able to provide the Movie & Music programs, with which the surround effect is applied to the movie and music sources for giving the users more enjoyment. YSS915 is pin compatible with and register compatible with YSS903 (KP2V).

用C51實現的拼音輸入法,這是改寫的網友 embuffalo、獨步上載在www.21ic.com自由發布區的由張凱原作的51上的拼音輸入法程序。 原作使用了一個二維數組用以查表，我認為這樣比較的浪費空間，而且每個字表的索引地址要手工輸入，效率不高。所以我用結構體將其改寫了一下。就是大家現在看到的這個。 因為代碼比較的大，共有6,000多漢字，這樣就得要12,000 byte來存放GB內碼，所以也是沒辦法的 :-( 編譯結果約為3000h,因為大部分是索引表，代碼優化幾乎無效。 在Keil C里仿真芯片選用的是華邦的W77E58，它有32k ROM, 256B on-chip RAM, 1K on-chip SRAM (用DPTR1指針尋址,相當于有1K的片上xdata)。條件有限，沒有上片試驗，仿真而已。 打算將其移植到AVR上，但CodeAVRC與IAR EC++在結構體、指針的定義使用上似乎與C51不太一樣，現在還未搞定。還希望在這方面有經驗的網友能給予指導。

ARM7硬件說明與開發 The ARM7 is a low-power, general purpose 32-bit RISC microprocessor macrocell for use in application or customer-specific integrated circuts (ASICs or CSICs). Its simple, elegant and fully static design is particularly suitable for cost and power-sensitive applications. The ARM7’s small die size makes it ideal for integrating into a larger custom chip that could also contain RAM, ROM, logic, DSP and other cells.
