These electric circuits can under the software control accurate, be rapid, highly effective complete the procedure designer preset the duty. From this looked that, singlechip has the function which the microprocessor does not have, it may alone complete the intellectualization control function which the modern industry control requests, this is singlechip biggest characteristic. However singlechip also is different with the single trigger, the chip before the development, it only has the function greatly strengthened ultra large scale integrated circuit, if entrusts with it the specific procedure, it then is youngest, the integrity microcomputer control system, it (PC machine) has the essential difference with the single trigger or the personal computing, singlechip application belongs to the chip level application, needs the user to understand singlechip chip the structure and the command system as well as other integrated circuit application technologies and the s
