用C51實(shí)現(xiàn)的拼音輸入法,這是改寫的網(wǎng)友 embuffalo、獨(dú)步上載在www.21ic.com自由發(fā)布區(qū)的由張凱原作的51上的拼音輸入法程序。 原作使用了一個(gè)二維數(shù)組用以查表，我認(rèn)為這樣比較的浪費(fèi)空間，而且每個(gè)字表的索引地址要手工輸入，效率不高。所以我用結(jié)構(gòu)體將其改寫了一下。就是大家現(xiàn)在看到的這個(gè)。 因?yàn)榇a比較的大，共有6,000多漢字，這樣就得要12,000 byte來存放GB內(nèi)碼，所以也是沒辦法的 :-( 編譯結(jié)果約為3000h,因?yàn)榇蟛糠质撬饕恚a優(yōu)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(dāng)于有1K的片上xdata)。條件有限，沒有上片試驗(yàn)，仿真而已。 打算將其移植到AVR上，但CodeAVRC與IAR EC++在結(jié)構(gòu)體、指針的定義使用上似乎與C51不太一樣，現(xiàn)在還未搞定。還希望在這方面有經(jīng)驗(yàn)的網(wǎng)友能給予指導(dǎo)。

This program demonstrates operation of ADC0 in polled mode. The ADC0 is // configured to use writes to AD0BUSY as its start of conversion source and // to measure the output of the on-chip temperature sensor. The temperature // sensor output is converted to degrees Celsius and is transmitted out UART0

Introduction A shared library is a collection of functions that are available for use by one or more applications running on a system. On Windows operating systems, the library is compiled into a dynamic link library (.dll) file. At run-time, the library is loaded into memory and made accessible to all applications.

The MIPS32® 4KEm™ core from MIPS® Technologies is a member of the MIPS32 4KE™ processor core family. It is a high-performance, low-power, 32-bit MIPS RISC core designed for custom system-on-silicon applications. The core is designed for semiconductor manufacturing companies, ASIC developers, and system OEMs who want to rapidly integrate their own custom logic and peripherals with a high-performance RISC processor. It is highly portable across processes, and can be easily integrated into full system-on-silicon designs, allowing developers to focus their attention on end-user products. The 4KEm core is ideally positioned to support new products for emerging segments of the digital consumer, network, systems, and information management markets, enabling new tailored solutions for embedded applications.

The TMS320C54x, TMS320LC54x, and TMS320VC54x fixed-point, digital signal processor (DSP) families (hereafter referred to as the ’54x unless otherwise specified) are based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. These processors also provide an arithmetic logic unit (ALU) that has a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. These DSP families also provide a highly specialized instruction set, which is the basis of the operational flexibility and speed of these DSPs.
