ABSTRACT:
In a data processing apparatus, having a user domain with domain storage space and an emulation domain with emulation storage space, emulates an instruction in the user domain by calling a program of instructions in the emulation domain. An instruction register connected to receive the sequence of instructions is partitioned into a plurality of fields. At least one field of the instruction register identifies a location for address information for an operand used in execution of the instruction. The instruction is decoded to generate a control code. The control code includes a branch signal to call the emulation program and a domain access control signal to indicate whether the emulation program requires access to the user domain storage base for execution. During execution of the emulation routine, domain access is implied by the location identified for the address information--a set of locations having been preselected as address registers for implied domain addressing.
