Abstract
마이크로프로세서의 운용프로그램을 격납한 메모리에서의 소비전력을 절감하는 메모리구성을 갖는 마이크로 프로세서 시스템이 개시된다.A microprocessor system having a memory configuration for reducing power consumption in a memory containing an operating program of a microprocessor is disclosed.
본 발명에 따른 마이크로프로세서 시스템은 마이크로프로세서와 상기 마이크로프로세서의 프로그램을 격납하는 롬을 갖는 시스템에 있어서, 상기 롬에 격납된 프로그램의 복사본이 저장되고, 상기 마이크로컴퓨터에 의해 액세스되는 램; 및 시스템의 초기동작시 상기 롬에 격납된 운용프로그램을 상기 롬에 격납시켜주는 프로그램로더를 포함함을 특징으로 한다.A microprocessor system according to the present invention comprises: a system having a microprocessor and a ROM storing a program of the microprocessor, the system comprising: a RAM in which a copy of a program stored in the ROM is stored and accessed by the microcomputer; And a program loader for storing the operating program stored in the ROM in the ROM during the initial operation of the system.
한 발명에 따른 마이크로프로세서 시스템에서는 롬에 격납된 프로그램을 램에 복사시켜두고 마이크로프로세서가 램을 액세스하여 프로그램을 독취하게 함으로써 시스템의 소비전력을 절감시키는 효과를 갖는다.In the microprocessor system according to the present invention, the program stored in the ROM is copied to RAM and the microprocessor accesses the RAM to read the program, thereby reducing power consumption of the system.
