Abstract
An execution processing module, while executing an execution module, stores an instruction type, and selectively stores a register value, a flag value, a branch source address, or a memory area value that may be updated by instruction execution according to the instruction type for use as trace data when a command read by a command reading module is a forward command. An UNDO execution processing module performs restoration processing using the trace data according to the instruction type when the command read by the command reading module is a backward command.
