Abstract
A renaming unit configured to rename source operands of instructions in a group. A renaming register maintains architectural to physical register mappings. Architectural to physical register mappings propagate from the renaming register through a chain of update units (U) over bus lines denoted with the architectural registers 0 to L. Update units (U) sequentially, in program order, insert physical register identifiers PR(i) allocated to instructions I(i) with destination operands DOP(i) on bus lines denoted with the destination operands DOP(i). Source operands of an instruction I(i) may be renamed to physical register identifiers after physical register identifiers allocated to instructions older than I(i) are sequentially, in program order, inserted on the bus lines, but before physical register identifiers allocated to I(i) and younger instructions are inserted on the bus lines. A source operand SOP(i) is renamed to a physical register identifier that propagates on a bus line denoted with SOP(i).
