Preload Instruction signals the memory system that instruction memory accesses from a specified address are likely in the near future. The memory system can respond by taking actions that are expected to speed up the memory accesses when they do occur, such as pre-loading the cache line containing the specified address into the instruction cache. For more information, see Behavior of Preload Data (PLD, PLDW) and Preload Instruction (PLI) with caches on page B2-1269. The effect of a PLI instruction is IMPLEMENTATION DEFINED. For more information, see Preloading caches on page A3-157 and Behavior of Preload Data (PLD, PLDW) and Preload Instruction (PLI) with caches on page B2-1269.
