Abstract

The wide spread of multimedia system demands a large area viewing display device which can inform a message to many people in open area. This paper is about the design of a large area viewing LED panel control system. The control system runs on 16 bit microprocessor MC68EC000 and has following functions: 16 line interlaced panel controller, memory, 16 channel priority interrupt, 2 channel direct memory access, 2 channel 12 bit clock and timer, 2 channel infrared remocon receiver, 2 channel RS-232C with 16 byte FIFO, IBM PC/AT compatible keyboard interface, ISA bus, battery backuped real time clock, batter backuped 256 byte SRAM and watch dog timer. The core circuits are implemented to ASIC, considering lower cost, higher reliability higher performance, smaller dimension, and lower power consumption. This is verified by simulation and fabricated in 0.6%u339B CMOS SOG processes. The total gate count is 39,083 and the clock frequency is 48%u3392. The fabricated ASIC is mounted on test board.
