Description: 采用FPGA控制ADS7844进行模数转换。ADS7844 是Burr_Brown公司推出的一种高性能、宽电压、低功耗的12 b串行数模转换器。它有8个模拟输入端，可用软件编程为8通道单端输入A／D转换器或4通道差分输入A／D转换器，其转换率高达200 kHz，而线性误差和差分误差最大仅为±1 LSB。-Using FPGA control ADS7844 analog to digital conversion. ADS7844 is a Burr_Brown the company introduced a high-performance, wide-voltage, low-power 12 b serial DAC. It has 8 analog inputs, available software programming for the 8-channel single-ended input A/D converter or 4-channel differential input A/D converter, the conversion rate of up to 200 kHz, while the maximum linearity error and differential error is only To ± 1 LSB.

Description:
As in hand multiplication (see Figure 2), we multiply the bits of the multiplier A
(a3a2a1a0) by the multiplicand (B) starting from the LSB (a0) to the MSB (a3). This forms
4 partial products a0B, a1B, a2B, and a3B. The resulting partial products are added with
each product shifted lefts by one bit position from its predecessor as shown in

Description: 利用 LSB 算法进行信息隐藏是在载体信号的空域进行的,它通过调整原始载体信息的最低几位来隐藏信息。文章首先简单叙述了B M P位图文件的文件格式, 然后根据 24位真彩色B M P位图格式与显示方式的特殊性,直接改变图像中像素的最后一位值来嵌入秘密文件,提出了一种对文字信息进行加密的有效方案。-LSB information hiding algorithm use of airspace carrier signal is carried by tuning the lowest bits of the original carrier of information to hide the information. Firstly, a brief description of the BMP bitmap file format, and then based on the particularity of 24 true color BMP bitmap format and display directly change the value of the last bit pixels in the image to embed secret document proposes a text information for effective program encrypted.
