But for UP (And maybe MP), If a timer interrupt (or IPI for SMP) fires in this small window of LDREX and STREX, Exception handler executes possibly adjustments cpu context and returns to the new task, however the stunning aspect comes in now, it executes 'CLREX' and therefore removing any special lock held by preceding thread. So how far better is utilizing LDREX and STREX than LDR and STR for atomicity with a UP technique ?

The nucleus is composed of positively billed protons and electrically neutral neutrons, each of that's approximately 1,836 periods as huge since the electron. Because atoms are so minute, their Homes need to be inferred by oblique experimental methods. Chief amid these is spectroscopy, which happens to be used to measure and interpret the electromagnetic radiation emitted or absorbed by atoms as they endure transitions from one particular Electrical power point out to a different.
