ABSTRACT:
A trap handler return for returning emulated results from a trap handler in a data processor includes source and destination register sets, and circuitry for transferring a specified value from the source register set to the destination register set. The trap handler return includes an instruction for returning the emulated result from the source register set to the destination register set. That instruction may be executed in the delay slot of an instruction which causes the transfer of control from the trap handler to the routine which caused the trap.
