Abstract

본 발명은 마이크로컴퓨를 탑재하고 있는 브이씨알이나 각종 전자제품의 기능을 프로그램적으로 변경하거나 추가하는 기술에 관한 것으로, 종래의 브이씨알에 있어서는 마스크 롬에 프로그램을 저장하게 되므로 제품의 생산단계에서 일단 프로그램이 저장된 후에는 그 프로그램의 변경이 불가능하게 되는 결함이 있었는 바, 본 발명은 이를 해결하기 위하여, 제품 출하 후 임의의 시점에서 외부로부터 전송되어 오는 프로그램을 저장하기 위한 플래쉬 메모리(22C)와, 상기 복조장치(21)를 통해 복조처리된 프로그램을 기록매체에 기록하는데 적당한 형식으로 변환하는 데이타 변환부(22A)와, 상기 데이타 변환부(22A)의 출력데이타를 플래쉬메모리(22C)에 재 저장하는 플래쉬메모리 제어부(22B)를 포함하여 구성한 것이다.The present invention relates to a technology for changing or adding functions of VISCAL or various electronic products on which a microcomputer is mounted in a programmable manner. In a conventional VISCAL, a program is stored in a mask ROM, The present invention provides a flash memory 22C for storing a program transmitted from the outside at an arbitrary point in time after the product is shipped, A data conversion unit 22A for converting the program demodulated through the demodulation device 21 into a format suitable for recording on a recording medium, and a data conversion unit 22A for restoring the output data of the data conversion unit 22A to the flash memory 22C And a flash memory control unit 22B.
