Abstract
A high-speed data processor capable of processing a special operation instruction such as a sequence operation instruction which is different from a normal execution instruction at high speeds. The high-speed data processor is capable of simultaneously reading and executing a special operation instruction which is a sequence operation instruction, even if an instruction prefetchable CPU is used, so that its data processing speed can be improved. Further, the data processor is also capable of causing the CPU to rapidly return from exceptional processing such as interrupt processing when the special operation is being executed, without making the operation result incorrect nor requiring any large instruction memory.
