Abstract
A general purpose register stores a 16-bit fixed length instruction. A bypass circuit speedily outputs the result of a comparison instruction when the next conditional branch instruction is executed. An ALU performs a logic process and so forth. A high speed multiplying device/high speed dividing device performs an arithmetic operation at high speed. An address calculating portion calculates an address. An instruction decoder/pipeline controlling portion decodes an instruction and controls a pipeline. A dedicated control register is used as an interrupt stack pointer or the like. An interrupt controller performs a multiple interrupt process. A coprocessor bus is disposed independently from a data bus.
