PROBLEM TO BE SOLVED: To provide a register transfer unit for an electronic processor. SOLUTION: A processing system has an instruction processor IP 1, register files 3 and 4 for storing data to be processed by the IP 1, such as a thread context, and a register transfer unit RTU 5 connected to the register files 3 and 4 and to the IP 1. The register files 3 and 4 may assume different states, readable and settable by both the RTU 5 and the IP 1. The IP 1 and the RTU 5 assume control of the register files 3 and 4 and perform their functions partially in response to states for the register files, and in releasing the register files 3 and 4 after processing, set the states. The invention is particularly applicable to multistreamed processors, wherein more register files 3 and 4 than streams may be implemented, allowing for at least one idle register file, and particularly applicable to a multistreamed processor in which background loading and unloading of data are accomplished.
