Abstract: With respect to the requirement of high speed RapidIO signal connection of high performance embedded system, this paper proposes a method for a front RapidIO interface on System-on-a-Programmable-Chip(SoPC). The method builds message transmission logic among RapidIO interface, Low Voltage Differential Signal(LVDS) image interface and RS422 control interface with RapidIO IP core and hardware programming based on the development platform of Xilinx VirtexII Pro. Hardware architecture diagrams and key design thoughts are introduced and the software architecture is presented.
