mnemonic-code将输入的汉子获取首字母转为大写或小写的字符串

将输入的汉子获取首字母转为大写或小写的字符串. 汉字转拼音 * @param str 带汉字的字符串 * @param split 拼音的分割符 * @param uppercase 是否大写 * @return {string} 返回转换为拼音的字符串 getMnemonic: function(str, split, uppercase): /** * 汉字转拼音首字母 * @param str 带汉字的字符串 * @param split 拼音的分割符 * @param uppercase 是否大写 * @return {string} 返回转换为拼音的字符串 */ getFirstMnemonic(str, split, uppercase);

The machine code of the mnemonic code "LDR r8, [r7, #4]" depends on the specific architecture and instruction set being used. However, I can provide an example of the machine code for this instruction in ARMv7-A assembly language. In ARMv7-A assembly language, the instruction "LDR r8, [r7, #4]" would be encoded as: ``` LDR r8, [r7, #4] ``` This instruction loads a 32-bit (4-byte) value from the memory address at `r7 + 4` into register `r8`. The machine code for this instruction would be: ``` 0x68 0x47 ``` This is represented as two bytes in hexadecimal notation. Note that the exact machine code for this instruction may differ depending on the specific architecture and implementation.
