본 발명은 펌웨어 업그레이드 장치에 관한 것이다.The present invention relates to a firmware upgrade apparatus.

일반적으로 펌웨어(Firmware)는 소프트웨어와 하드웨어의 중간쯤에 위치하며 상기 소프트웨어와 하드웨어를 연결시켜 주는 매개체이다.Generally, firmware is located between the software and the hardware and is a medium that connects the software and the hardware.

예를 들어, 장치의 메인보드에 여러 가지 하드웨어들이 설치되어 있는 경우, 상기 장치에 전원이 입력되더라도 상기 장치는 혼자서 동작할 수 없고, 상기 동작을 위해서는 각각의 하드웨어를 엑세스하는 적당한 매개수단이 필요한데 이것이 펌웨어이다.For example, if various hardware is installed on the main board of the device, even if the device is powered on, the device cannot operate by itself, and the operation requires appropriate mediation means to access each hardware. It is firmware.

이러한 펌웨어는 하드웨어를 동작시키고 소프트웨어와 완충작용을 하며, 소프트웨어에서 제어하는 내용을 하드웨어에 전달해준다. 상기 펌웨어는 장치에서 메모리의 폼 영역에 들어 있기 때문에 장치에 전원이 꺼져도 데이터는 계속 유지되므로, 상기 장치가 켜질 때 필요한 여러 가지 루틴들과 자동적으로 작동되는 여러 가지 프로그램을 포함한다.This firmware runs the hardware, buffers the software, and passes the software control to the hardware. Since the firmware resides in the form area of the memory at the device, the data is retained even when the device is powered off, and thus includes various routines and various programs that operate automatically when the device is turned on.

따라서 상기 펌웨어는 어떠한 프로그램상의 문제가 있는 경우 또는 새로운 기능을 추가하고자 하는 경우, 상기 장치 내의 메모리(예를 들어, 롬)에 저장된 펌웨어를 업그레이드시키게 된다.Therefore, the firmware upgrades the firmware stored in a memory (eg, a ROM) in the device in case of any program problem or to add a new function.

특히 펌웨어 업그레이드는 주로 퍼스널컴퓨터 또는 이동 전화 단말기 부분에서 주로 이루어지게 되고, 상기 퍼스널컴퓨터에 삽입되는 카드(예를 들어,사운드 카드, VGA 카드 또는 모뎀 카드)나 이동 전화 단말기에는 펌웨어를 업그레이드할 수 있는 기능을 가지게 되므로, 상기 펌웨어 업그레이드할 때, 종래에는 도 1에 도시한 바와 같이, 무선모뎀(11)과 직렬통신 인터페이스(RS-232)로 연결되는 퍼스널 컴퓨터(12)간에 상기 직렬통신 인터페이스(RS-232)를 전기적으로 매칭시켜 주는 지그 보오드(JIG BOARD)(13)를 접속하여 파일을 다운 로딩하면서 펌웨어를 업그레이드하게 된다.In particular, the firmware upgrade is mainly performed in the personal computer or mobile phone terminal part, and the firmware can be upgraded in a card (for example, a sound card, a VGA card or a modem card) or a mobile phone terminal inserted into the personal computer. When the firmware is upgraded, the serial communication interface RS is connected between the wireless modem 11 and the personal computer 12 connected to the serial communication interface RS-232, as shown in FIG. 1. JIG BOARD 13, which electrically matches -232), is connected to upgrade the firmware while downloading a file.

그러나 상기 지그 보오드(13)는 최대 전송속도가 120Kbps 이므로, 대용량의 펌웨어 업그레이드할 때, 현재의 전송속도로는 수 Mbps 펌웨어를 다운로드 하려면 600 ~ 800초의 많은 시간이 소요되는 문제점이 있고, 또한 상기 무선모뎀(11)과 퍼스널 컴퓨터(12) 간에 펌웨어 업그레이드를 위해서 반드시 직렬통신 인터페이 스(RS-232)를 매칭시키는 지그 보오드(13)를 접속하여야 하는데 따른 구성이 복잡한 문제점이 있다.However, since the maximum transmission speed of the jig board 13 is 120 Kbps, when upgrading a large capacity firmware, there is a problem that it takes a lot of time of 600 ~ 800 seconds to download a few Mbps firmware at the current transmission speed, and also the wireless In order to upgrade the firmware between the modem 11 and the personal computer 12, a jig board 13 that matches the serial communication interface RS-232 must be connected.

본 발명은 펌웨어 업그레이드를 위한 다운로드 속도를 개선한다.The present invention improves the download speed for firmware upgrades.

본 발명은 무선모뎀의 펌웨어 업그레이드 장치가 데이터를 무선 송수신하는 무선칩; 상기 무선칩으로부터 수신된 데이터를 연산처리하는 중앙처리부; 및 상기 중앙처리부로부터 입력받은 팜웨어 업그레이드용 데이터를 펌웨어 업그레이드가 필요한 장치에 다운 로드하는 범용직렬버스 포트를 포함한다.The present invention provides a wireless chip for wirelessly transmitting and receiving data by a firmware upgrade apparatus of a wireless modem; A central processing unit configured to process data received from the wireless chip; And a general-purpose serial bus port for downloading the palmware upgrade data received from the central processing unit to a device requiring firmware upgrade.
