可以將以bit為單位進行處理的算法擴展到8位,即以Byte為單位進行處理。由于有8個bit,所以有2^8種選擇。這樣明顯會使運行時 間大為減少,速度明顯更快,但是也有它的缺點,即,占用資源太大,所以綜合考慮速度和 資源兩點,采用半字節查表法。即以半 Byte為單位進行處理。由于有4個bit,所以有2^4種選擇。

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.

Electromagnetic scattering from the trees above a tilted rough ground plane generated by the stochastic Lidenmayer system is studied by Monte Carlo simulations in this paper.The scattering coefficients are calculated in three methods:coherent addition approximation,tree-independent scattering,and independent scattering.

A complete set of bit banged, software driven I2C routines I created for any PIC device - and they work!! These functions are single master only functions, and are ideal for communicating with things like EEPROMs, LCD Drivers, ADC Converters etc
