Data processing system having built-in memory in micro-processor

摘要: The present invention is a data processing system, which comprises microprocessor. microprocessor central unit (CPU) and built-in non-volatile program memory for storing startup program. system further volatile memory, permanent an application permanently, bus connected to the microprocessor, power supply providing system. While switch of turned on, stored in initialized first transmit via bus, so that CPU only needs call execute instead doesn't need read repeatedly avoid reducing efficiency.
