![Screenshot of an interactive Intel instruction visualizer for VPINSRB. It shows the syntax VPINSRB xmm1, xmm2, r32, imm8 and explains that one byte from src2 is inserted into a selected byte position of src1. In the example, imm8 = 0x02, so byte index 2 is selected. src1 contains bytes 0xA0 through 0xAF, while src2[0] is 0x1F. The destination row highlights byte 2 changing from 0xA2 to 0x1F; all other destination bytes remain unchanged. A bit diagram at the bottom shows the low four immediate bits as 0010, corresponding to selection index 2. https://serpent7776.github.io/simdvis/pinsr.html#vpinsrb](https://pbs.twimg.com/media/HSwO4mXWkAAcTTD.jpg?name=orig)
