The document discusses various data movement instructions in microprocessors, including: 1) LEA instructions that load an effective address into a register without transferring data. 2) LDS, LES, LFS, LGS, and LSS instructions that load a segment register and offset address into a register. 3) String instructions like LODS, STOS, MOVS, INS and OUTS that transfer data between memory and registers, using DI, SI registers and direction flag to determine transfer direction.
