| Abstract: | The design of a signal process platform based on loongson 3A is introduced. The platform is constituted by two loongson 3A chips which are connected by HT0 interface. The platform supplies two RapidIO channels and two Gigabit Ethernet channels. The article analyses the difficult problem of software transplant of the platform and the vxWorks 6.80S deeply. At last, the article lists the testing data and compares to the data of the other platforms and draws a conclusion. |
