 ### 填充
 - **VSPLTISB** "Vector Splat Immediate Signed Byte". This instruction is used to fill a vector register with a specified 8-bit signed integer.填充立即数到目标向量寄存器。
 - **VSPLTB** "Vector Splat Byte". This instruction is used to replicate a specified byte across all elements of a vector register.从源向量寄存器中取指定位置的字节，填充到目标向量寄存器。
+- **VSPLTISW** "Vector Splat Immediate Signed Word". This instruction is used to fill a vector register with a specified 16-bit signed integer.
+- **VSPLTW** "Vector Splat Word". This instruction is used to replicate a specified word (32-bit element) across all elements of a vector register.
 
 ### 从内存加载(Load)数据
 - **LXVDSX** "Load Vector Doubleword Scalar Indexed". This instruction is used to load a doubleword (64-bit element) from memory into a vector register.从指定内存位置加载64位数据，将其存储到目标向量寄存器的lower half（byte index from 0-7）。
