A simplified explore the construction of the atomExplore an atom's inside to discover the structure of its nucleus, protons, and electrons.
But for UP (And perhaps MP), If a timer interrupt (or IPI for SMP) fires On this tiny window of LDREX and STREX, Exception handler executes potentially alterations cpu context and returns to the new endeavor, however the stunning portion comes in now, it executes 'CLREX' and as a result eradicating any exceptional lock held by preceding thread. So how far better is utilizing LDREX and STREX than LDR and STR for atomicity with a UP process ?
ARM ARM suggests that Load and Retail store Guidance are atomic and it's execution is sure to be entire right before interrupt handler executes. Confirmed by checking out
Rutherford atomic model Physicist Ernest Rutherford envisioned the atom like a miniature solar process, with electrons orbiting all-around a large nucleus, and as generally vacant Place, While using the nucleus occupying only a very little Portion of the atom.
