WebNov 30, 2024 · The issue that is affecting x86 to ARM migration is called memory consistency model. Among the issues in memory consistency model, one of them is called "total store ordering" (TSO), and this is ... WebOct 6, 2016 · Here, we describe the first lazy sequentialization approach for the total store order (TSO) and partial store order (PSO) memory models. We replace all shared memory accesses with operations on a shared memory abstraction (SMA), an abstract data type that encapsulates the semantics of the underlying WMM and implements it under the simpler …

Webstore-order’ (TSO) memory model. We choose the TSO memory model as the basis of our extension for two reasons:(1)it is a mainstream practical weak memory model (followed by the x86 and SPARC architectures); and(2)it has an intuitive operational semantics in terms of processor-local buffers [Sewell et al. 2010].
