Description

디코더칩 판별방법Decoder chip identification method

본 발명은 디코더를 구동하는 프로그램들을 마이콤에 설정하고, 채용된 디코더의 제작정보를 통해 디코더칩의 모델을 판별하여 대응하는 프로그램으로 동작할 수 있도록 한 디코더칩 판별방법에 관한 것이다. The present invention relates to a decoder chip discrimination method in which programs for driving a decoder are set in a microcomputer, and a model of the decoder chip is determined through manufacturing information of a decoder used to operate as a corresponding program.

일반적으로, 디코더는 부호화 신호를 수신하고, 원래의 정보 신호를 찾아내기 위한 장치이다. 이러한 디코더는 제작회사에 따라 서로 다른 디코더 동작처리 프로그램에 의해 동작한다. 그러므로, 어떤 회사에서 제작된 디코더를 채용했는지에 따라 마이콤의 프로그램도 달라지게 된다. 현재는 플래시 롬(FLASH ROM)의 초기화를 위한 마이콤 내부 메모리의 사용영역이 4kbyte로 제한되어 있다. 따라서, 광디스크장치에 채용된 디코더 칩(decoder chip)에 따라 디코더 동작프로그램을 각각 만들어 마이콤에 기억시켜야 했다. Generally, a decoder is an apparatus for receiving an encoded signal and finding the original information signal. These decoders are operated by different decoder operation processing programs depending on the manufacturer. Therefore, the program of Micom will vary depending on which company uses the decoder. Currently, the use area of the microcomputer internal memory for initializing the flash ROM is limited to 4 kbytes. Therefore, the decoder operation programs must be made and stored in the microcomputer according to the decoder chip employed in the optical disk device.

이와같이, 종래의 광디스크장치는 한 모델에 대해 디코더칩을 다르게 사용할 경우, 예를들어 A모델에 대해 B 또는 C의 디코더칩을 사용할 경우, 같은 모델임에도 불구하고 디코더칩이 각기 다르기 때문에 마이콤의 디코더 동작 프로그램도 달라져야 한다. 즉, B디코더칩에 대해서는 B동작프로그램을, C디코더칩에 대해서는 C동작프로그램을 따로 만들어야 하는 불편함이 있었다.As described above, in the conventional optical disc device, when the decoder chip is used differently for one model, for example, when the decoder chip of B or C is used for the A model, the decoder chip operation is different because the decoder chips are different despite the same model. The program must also be different. In other words, it is inconvenient to make a B operation program for the B decoder chip and a C operation program for the C decoder chip.

따라서, 본 발명의 목적은 적어도 둘 이상의 서로 다른 디코더칩의 동작처리프로그램을 마이콤에 저장하고, 채용된 디코더칩의 모델을 판별하여 판별된 디코더칩에 대응하는 동자처리프로그램을 선택하는 디코더칩 판별방법을 제공함에 있다. Accordingly, an object of the present invention is to provide a decoder chip discrimination method for storing operation processing programs of at least two different decoder chips in a microcomputer, determining a model of the adopted decoder chip, and selecting a pupil processing program corresponding to the determined decoder chip. In providing.

위와같은 목적을 달성하기 위한 본 발명의 특징은 디코더칩의 모델에 따른 동작처리프로그램을 선택하는 방법에 있어서, 적어도 둘 이상의 서로 다른 모델에 대한 디코더의 동작처리프로그램들을 마이콤에 저장하는 프로그램 저장단계, 디코더의 제작정보가 기록된 제작레지스터를 읽어 채용된 디코더의 모델을 판별하는 디코더 모델판별단계 및 상기 디코더의 동작처리프로그램들중 상기 판별된 디코더에 해당하는 디코더 동작처리프로그램을 선택하는 디코더칩 판별방법에 있다.A feature of the present invention for achieving the above object is a method for selecting an operation processing program according to the model of the decoder chip, program storage step of storing the operation processing programs of the decoder for at least two different models in the microcomputer, A decoder model discrimination step of determining a model of a decoder employed by reading a manufacturing register in which manufacturing information of a decoder is recorded and a decoder chip discrimination method of selecting a decoder operation processing program corresponding to the determined decoder among the operation processing programs of the decoder. Is in.

이하, 첨부한 도면을 참조하여 본 발명의 바람직한 일 실시예를 상세히 설명하겠다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 디코더칩 판별방법이 적용된 장치를 도시한 도면이다. 전원부(12)는 마이콤(14)으로 전원을 인가한다. 마이콤(14)은 디코더칩의 종류에 따른 동작프로그램을 기저장하고 있으며, 디코더(16)의 제작레지스터를 읽어 디코더칩의 모델을 판별하고, 판별된 디코더칩의 모델에 따라 프로그램을 선택한다. 1 is a diagram illustrating an apparatus to which a decoder chip discrimination method of the present invention is applied. The power supply unit 12 applies power to the microcomputer 14. The microcomputer 14 stores an operation program corresponding to the type of the decoder chip, reads the manufacturing register of the decoder 16, determines the model of the decoder chip, and selects the program according to the determined model of the decoder chip.

도 2는 본 발명의 동작을 설명하기 위한 흐름도이다.2 is a flowchart illustrating the operation of the present invention.

먼저, 전원부(12)는 광디스크장치를 구동하기 위한 전원을 마이콤(14)으로 인가한다(제 210단계). 전원이 인가되면, 마이콤(14)은 디코더칩(16)의 제작레지스터를 읽어 디코더칩(16)의 제작정보를 독출한다(제 220단계). 마이콤(14)은 제작레지스터로부터 독출한 제작정보를 통해 디코더칩의 종류를 판별한다(제 230단계). 마이콤(14)은 적어도 둘 이상의 서로 다른 모델에 대한 디코더 동작처리프로그램들을 기저장하고 있으며, 이들중 판별된 디코더칩에 해당하는 디코더 동작처리프로그램을 선택한다(제 240단계). 이후, 광디스크장치의 디코더는 선택된 디코더 처리프로그램에 따라 동작한다(제 250단계).First, the power supply unit 12 applies the power for driving the optical disk device to the microcomputer 14 (step 210). When the power is applied, the microcomputer 14 reads the manufacturing register of the decoder chip 16 and reads the manufacturing information of the decoder chip 16 (step 220). The microcomputer 14 determines the type of the decoder chip through the manufacturing information read from the manufacturing register (step 230). The microcomputer 14 previously stores decoder operation processing programs for at least two different models, and selects a decoder operation processing program corresponding to the determined decoder chip (step 240). The decoder of the optical disc apparatus then operates in accordance with the selected decoder processing program (step 250).

상술한 바와같이, 본 발명은 광디스크장치에 채용된 디코더칩의 모델을 판별하고, 마이콤에 설정된 서로 다른 모델에 대한 디코더칩의 프로그램들중 현재 채용된 디코더칩에 대응하는 동작처리 프로그램을 선택하여 동작할 수 있도록 한다. As described above, the present invention determines the model of the decoder chip employed in the optical disk device, and selects an operation processing program corresponding to the decoder chip currently employed among the programs of the decoder chip for different models set in the microcomputer to operate. Do it.
