General purpose processor having a variable bitwidth

摘要: A 32-bit processor control unit receives from a memory an instruction. The then determines whether the received instruction is intended for or 16-bit processor. If analyzed to be instruction, controls with aid of two units. sends mode signal each One units one processors which are divisions while other present invention makes it possible have single, wide bitwidth serve as plurality narrow depending upon type processing. Various operations can performed in parallel, thereby improving performance.
