A pipelined processor including one or more units having storage locations not directly accessible by software instructions. The processor includes a load-store unit (LSU) in direct communication with the one or more units for accessing the storage locations in response to special instructions. The processor also includes a requesting unit for receiving a special instruction from a requestor and a mechanism for performing a method. The method includes broadcasting storage location information from the special instruction to one or more of the units to determine a corresponding unit having the storage location specified by the special instruction. Execution of the special instruction is initiated at the corresponding unit. If the unit executing the special instruction is not the LSU, the data is sent to the LSU. The data is received from the LSU as a result of the execution of the special instruction. The data is provided to the requester.
