Description: 通过对于模2除法的研究
可以得到如下方法:
1. 把信息码后面加上p-1位的0,这个试验中p是6位,即在输入的信息码后面加上“00000”。把这个17位的被除数放入input中。
2. 在得到被除数input之后,设计一个在被除数上移动的数据滑块变量d,把input中的最高位开始逐次复制给变量d。
3. 如果d的最高位为1,由变量d和变量p做异或运算;如果d的最高位为0则不运算或者做多余的异或‘0’的运算。
4. 把滑块变量d往后滑动一位。
5. 循环步骤(3,4)11次。
6. 执行步骤3。
7. 得到余数c,把c转成信号输出。
-Through the 2-mode research division will be as follows: 1. Information code followed by the p-1-bit 0, this test p is 6, that is, the information in the input code after 00000. This 17 Add input in the dividend. 2. After receiving input dividend, dividend on the design of a mobile data slider variable d, the highest input in the beginning of successive copied to the variable d. 3. If the highest d for 1, by the variable d and variable p do XOR operations if d the highest computing to 0 or do not redundant XOR 0 arithmetic. 4. The slider sliding variable d next one. 5. Cycle of steps (3,4) 11. 6. Steps 3.7. Be more than a few c, the c into the output signal. Platform: |

Description: DS18B20引脚功能
GND地,DQ数据总线,VDD电源电压
18B20共有三种形式的存储器资源,它们分别是:
ROM 只读存储器,用于存放DS18B20ID编码,其前八位是单线系列编码,后面48位是芯片唯一的序列号,最后8位是以上56位的CRC码。DS18B20共64位ROM
RAM 数据暂存器,数据掉电后丢失,共9个字节,每个字节8位,第1、2个字节是温度转换后的数据值信息,EEPROM 非易失性记忆体,用于存放长期需要保存的数据,上下限温度报警值和校验数据
-DS18B20 Function GND Ground pin, DQ data bus, VDD supply voltage 18B20 There are three forms of memory resources, they are: ROM read-only memory for storing DS18B20ID coding, the top eight single-family is encoded, followed by 48 is the chip serial number only, over the last eight is 56-bit CRC code. DS18B20 total of 64-bit ROM RAM data store, data loss after power-down, a total of 9 bytes, each byte 8-bit, 1, 2 bytes of temperature data converted value information, EEPROM non-volatile volatile memory for storage of long-term need to preserve data, upper and lower temperature alarm and calibration data Platform: |

Description: 赛灵思的循环冗余校验(CRC),内服详细说明-The Cyclic Redundancy Check (CRC) is a checksum technique for testing data reliability and
correctness. This application note shows how to implement Configurable CRC Modules with
LocalLink interfaces. Users tailor the module features to suit the protocol or application
implemented in their system. The user-specified options for each of the configurable features
are input parameters to the VHDL code for the modules. The VHDL source files for the CRC
modules are coded using generate statements. The modules have two LocalLink interfaces: an
upstream interface (US) and a downstream interface (DS) Platform: |
