摘要： A data processing apparatus and method employing multiple register sets is disclosed. The data processing apparatus has processing logic for performing data processing operations and a register bank for storing data associated with the processing logic. The register bank has at least one register group, each register group having a plurality of register sets. The processing logic has an operating state associated with each register group defining how that register group is used, a first operating state being a state in which each register set in the register group is used to support an independent execution thread of the processing logic, and a second operating state being a state in which the register sets of the register group are collectively used to support a single execution thread of the processing logic. Control logic is provided to control how the register sets of each register group are used dependent on the operating state associated with that register group. This has been found to provide a particularly efficient use of the registers within the data processing apparatus.
