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 r3, [r5, #2]" depends on the specific architecture and instruction set being used. However, I can provide an example of the machine code for this instruction in ARMv8-A assembly language. In ARMv8-A assembly language, the instruction "LDR r3, [r5, #2]" would be encoded as: ``` LDR X3, [X5, #2] ``` This instruction loads a 64-bit (8-byte) value from the memory address at `X5 + 2` into register `X3`. The machine code for this instruction would be: ``` 0xB8 0x21 0x58 0xB8 ``` This is represented as four bytes in hexadecimal notation. Note that the exact machine code for this instruction may differ depending on the specific architecture and implementation.
