Process Splet25. apr. 2024 · To alleviate this problem Intel introduced the PAUSE instruction which provides a hint that a spin-wait loop is running and throttles the CPU core in some architecture specific way in order to reduce power usage and … Splet06. jan. 2024 · The PAUSE instruction provides a hint to the processor that the code sequence is a spin-wait loop. The processor uses this hint to avoid the memory order violation in most situations, which greatly improves processor performance. For this reason, it is recommended that a PAUSE instruction be placed in all spin-wait loops. ill fly away tab
