In the embedded flight control system，to meet it′s miniaturization and integration，it needs to control multi-serial ports to communicate with external equipments. TMS320C6748 is used to be a processor, which interfaces to TL16C754 by DSP′s EMIF，enlarges multi-selective signals to make use of 74LS138，and achieves multi-serial ports communication function with TL16C754. The driver is designed with the real-time operating system SYS/BIOS，which minishes design difficulty, and cuts empolder period. The test results show that the design method can achieve complete reception of multi-channel data, and the data transmission is complete and reliable.
