IEEE 1149.1 기반 LED전광판 모듈 위치 자동 설정 기법

다국어 초록 (Multilingual Abstract)

We propose a module address mapping scheme and its architecture to automatically get the module position in a large-size LED screen. In contrast to previous methods considering the cabling order to generate the module address, the proposed method doesnt require such a complex process due to the MAC address utilization as an unique module ID. Next, spatially adjacent modules exchange MAC addresses mutually, and this is based on the automatic module position setup program operated by the LED screen controller. Furthermore, it is expected that IEEE 1149.1 standard protocols and architecture used to save, control and transmit adjacent module information can reduce the time and implementation costs noticeably.
