1.5 Program Order and Dependencies

Resolving Operand Dependencies

Operands include registers, memory, and condition bits. Each operand type has its own dependency logic. In the R10000 processor, dependencies are resolved in the following manner:

register dependencies are resolved by using register renaming and the associative comparator circuitry in the queues
memory dependencies are resolved in the Load/Store Unit
condition bit dependencies are resolved in the active list and instruction queues
