| Abstract: | This paper presented a kind of scheme to realize PC104 bus, which based on the ARM embedded systems, by having a test and research on the platform of S3C2440. This scheme realized the function of PC104 bus through the CPLD chip, and completed the operation between ARM9 chip and external equipment by im- plementing the timing of PC104 bus related signals. The experiment showed that the function of PC104 bus can be performed well by the CPLD chip. |
