用C51寫的普通拼音輸入法源程序代碼: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)。

The Tri-Mode Ethernet MAC (TEMAC) UltraController-II module is a minimal footprint,embedded network processing engine based on the PowerPC™ 405 (PPC405) processor coreand the TEMAC core embedded within a Virtex™-4 FX Platform FPGA. The TEMACUltraController-II module connects to an external PHY through Gigabit Media IndependentInterface (GMII) and Management Data Input/Output (MDIO) interfaces and supports tri-mode(10/100/1000 Mb/s) Ethernet. Software running from the processor cache reads and writesthrough an On-Chip Memory (OCM) interface to two FIFOs that act as buffers between thedifferent clock domains of the PPC405 OCM and the TEMAC.

On the LPC13xx, programming, erasure and re-programming of the on-chip flash can be performed using In-System Programming (ISP) via the UART serial port, and also, can be performed using In-Application Programming (IAP) calls directed by the end-user code. For In-System Programming (ISP) via the UART serial port, the ISP command handler (resides in the bootloader) allows erasure of one or more sector (s) of the on-chip flash memory.

The power of programmability gives industrial automation designers a highly efficient， cost-effective alternative to traditional motor control units （MCUs）。 The parallel-processing power， fast computational speeds， and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control （FOC）。
Additionally， Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing （DSP） that can tackle compute-intensive functions such as PID Controller， Clark/Park transforms， and Space Vector PWM.
The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving， proven， motor-control reference designs. The kit also shortens the process of developing custom control capabilities， with integrated peripheral functions （Ethernet， PowerLink， and PCI® Express）， a motor-control FPGA mezzanine card （FMC） with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators， and prototyping support for evaluating alternative front-end circuitry.
