A configurable SoC platform design based on LEON microprocessor and Linux operation system

A configurable SoC platform based on LEON3 microprocessor and Linux operation system (SnapGear) is presented in this paper. A novel method is proposed, which adds a new peripheral (SPI) to the SoC and designs a device driver according to Linux device model. In this way, customers can add hardware to LEON SoC and enhance the system functions by using device driver easily, which are proved by the testing results.
