초록

본 논문에서는 저가의 소형 PCR 장치에 적합한 펌웨어를 설계하고 구현하였다. 제안된 펌웨어는 실행코드 크기를 최소화하기 위해서 운영체제의 도움을 받지 않고 하드웨어 인터럽트만을 이용하여 실시간 작업들을 동시에 제어한다. 또한 제안된 펌웨어는 usb 통신을 이용하여 PC로부터 동작 과정을 입력받아 마이크로콘트롤러에 연결된 부속장비들을 구동하고, 구동결과를PC로 전달하여 사용자에게 출력하는 주컴퓨터-국소장치 구조에 적합하도록 설계되었다. 제안된 펌웨어를 microchip사의 PIC18F4550 칩에 실제로 탑재하여 저가의 소형 PCR 장치를 제작하였고, 제작한 PCR 장치가 기존 상용 PCR 장치는 제작 비용과 부피를 대폭 줄이면서도 유사한 DNA 증폭 결과를 보임을 확인하였다.

In this paper, we design and implement a firmware for low-cost small PCR devices. To minimize machine code size, the proposed firmware controls real-time tasks simultaneously only with support of the hardware interrupt, but without support of the operating system program. The proposed firmware has the host-local structure in which the firmware receives operation commands from PC and sends operation results to PC through usb communication. We implement a low-cost small PCR device with the proposed firmware loaded on microchip PIC18F4550 chip, and verify that the implemented PCR device significantly reduces cost and volume size of existing commercial PCR devices with a similar performance.
