class MemoryGroup

Declaration

class MemoryGroup { /* full declaration omitted */ };

Description

A node of a memory dependency graph. A MemoryGroup describes a set of instructions with same memory dependencies. By construction, instructions of a MemoryGroup don't depend on each other. At dispatch stage, instructions are mapped by the LSUnit to MemoryGroups. A Memory group identifier is then stored as a "token" in field Instruction::LSUTokenID of each dispatched instructions. That token is used internally by the LSUnit to track memory dependencies.
