+# 基于cortex-m3-emulator实现哈希表并测试验证##
+
+## 1. 简介
+利用c语言实现了哈希表（HashMap），包括添加键值对(Put)，获取键对应的值(Get), 删除健（Delete），清空哈希表(Clear)， 迭代遍历哈希表(hashMapIterator)等功能
+操作。
+
+利用数组（Entry）作为存储空间，利用链表(*next)解决冲突。当哈希表的大小超过数组大小后，为避免发生冲突过多的情况，可以对哈希表扩容。
+
+## 2. 数据结构设计说明
+键值对结构
+typedef struct entry {
+    void * key;             // 键
+    void * value;           // 值
+    struct entry * next;    // 冲突链表
+}*Entry;
+
+哈希结构
+typedef struct hashMap {
+    int size;           // 当前大小
+    int listSize;       // 有效空间大小
+    HashCode hashCode;  // 哈希函数
+    Equal equal;        // 判等函数
+    Entry list;         // 存储区域
+    Put put;            // 添加键的函数
+    Get get;            // 获取键对应值的函数
+    Remove remove;      // 删除键
+    Clear clear;        // 清空Map
+    Exists exists;      // 判断键是否存在
+    Boolean autoAssign;	// 设定是否根据当前数据量动态调整内存大小，默认开启
+}*HashMap;
+
+包括以下函数功能，分别为：
+`createHashMap`：创建一个哈希结构
+`defaultPut`：添加键值对
+`defaultGet`：获取键对应值
+`defaultRemove`：删除指定键的键值对
+`defaultExists`：判断键值是否存在
+`defaultClear`：清空Map的函数类型
+`resetHashMap`：重新构建哈希表
+
+
+## 3. 测试程序说明
+测试了哈希表的插入键值对(Put)，判断键是否存在(Exist)，获取键对应的值(Get)， 删除健（Delete），迭代遍历哈希表(hashMapIterator)，清空哈希表(Clear)等操作。
+并展示了利用链地址法解决哈希冲突的示例, 两个不同的人(Bob和Li Ming)的hashcode相同。
+
+## 4. 运行结果（##需结合运行测试截图按步骤说明##）
+![image](ConfigOpen.png)
+打开menuconfig之后，将test_hash_map开启(y)，保存后退出
+
+![image](CompileSuccess.png)
+编译XiZi-cortex-m3-emulator.elf成功
+
+![image](ShellCommand.png)
+启动qemu模拟Xiuos操作系统，验证TestHash注册Shell命令
+
+![image](TestHash.png)
+执行TestHash命令，打印测试结果。

+# 基于k210-emulator实现基数树并测试验证
+
+## 1. 简介
+
+基于矽璓模拟器k210-emulator，实现基数树，并编写测试程序在shell终端打印结果。
+
+## 2. 数据结构设计说明
+
+基数树节点设计为：
+
+```c
+typedef struct _node {
+​    void* value;
+​    struct _node* next[NODE_SIZE];
+} node;
+```
+
+其中，节点在树中的路径即为键，`value` 存储值，`NODE_SIZE` 定义为 128，足以容纳所有 ASCII 值。
+
+一共实现了 5 个函数，分别为：
+
+- `CreateNode`：创建一个基数树节点
+- `InsertNode`：将一对键值对插入基数树
+- `DeleteNode`：删除指定键的键值对
+- `FindNode`：查找指定键对应的值
+- `DestroyTree`：销毁整个基数树
+
+## 3. 测试程序说明
+
+测试程序 `TestRadix` 已经注册为 shell 命令，可以调用执行。
+
+测试程序定义了以下键值对：
+
+```c
+char keys[][MAX_WORD_LEN] = {
+    "what",
+    "where",
+    "why",
+    "how",
+    "hello!",
+    "apple",
+    "12345"
+};
+int values[] = {1, 2, 3, 4, 5, 6, 7};
+```
+
+1. 程序的第一部分创建了基数树，并且将定义的 7 个键值对的前 6 个插入了基数树，然后分别查找 7 个键，前 6 个均可以找到对应的值，最后一个未插入，因此无法找到
+2. 程序的第二部分从基数树中删除了 `where` 和 `how` 两个键，再次分别查找 7 个键，删除的键值对和未插入的键值对均无法找到
+3. 程序的第三部分重新插入了已删除的 `where` 和未插入过的 `12345` ，再次分别查找 7 个键，新插入的值可以检索到
+4. 程序的第四部分将基数树销毁，再次分别查找 7 个键，所有的键值对均无法找到
+
+## 4. 运行结果（##需结合运行测试截图按步骤说明##）
+
+1. 在工作区终端中输入命令：`make BOARD=k210-emulator menuconfig`，进入配置页面
+![fig1](fig1.png)
+2. 依次进入 `APP_Framework` -> `Applications` -> `test app` 目录，将 `Enable application test function` 选项置为 `Y`
+![fig2](fig2.png)
+3. 进入 `Enable application test function` 将 `Config test radix tree` 选项置为 `Y`
+![fig3](fig3.png)
+4. 一直选择 `Exit` 退出配置，在最后需要确认的页面选择 `Yes` 保存配置
+![fig4](fig4.png)
+5. 执行编译命令：`make BOARD=k210-emulator`，正常情况下应当编译无误
+![fig5](fig5.png)
+6. 在 `qemu` 中运行：`qemu-system-riscv64 -nographic -machine sifive_u -bios build/XiZi-k210-emulator.elf`
+![fig6](fig6.png)
+7. 在 shell 中运行命令 `TestRadix`，执行结果与预期一致，验证完成。

+  * M241支持2路485串口，本次采用的是serial2。波特率：9600，数据位：8位，停止位：1位，校验：偶校验
+
+## 存储区
+
+- 存储区MW区。
+
+## 通信测试
+
+（1）共测试INT16共1种类型数据。
+
+（2）测试MW区数据。
+
+（3）MW区数据测试，用功能码03，以字为单位读取。如读MW100，则配方文件中起始地址则直接写100即可。
