Value-based replay eliminates the need for content-addressable memories in the load queue, removing one barrier to scalable outof-order instruction windows. Instead, correct memory ordering is maintained by simply re-executing certain load instructions in program order. A set of novel filtering heuristics reduces the average additional cache bandwidth demanded by value-based replay to less than 3.5 percent.
