RTL Design of SpaceWire Protocol and AMBAInterface with LEON Processor

Abstract

With the progressive increase in the use of FPGAs for prototyping the embedded systems on a chip, the designing of IPs (Intellectual property) has also been increasing which are used to enhance the features of the designs. To attach an IP with one of the buses in the design, the designer has to create an interface for it. Some open source processors available like LEON and buses like AMBA bus . This Project reports the designing of SpaceWire Protocol and AMBA interface with LEON3 processor used as a platform for application specification SoC. The European Space Agency (ESA) proposed the SpaceWire standards for reliable satellite on-board networking at high speed upto hundreds of Mbits/sec. LEON Processor supports radiation tolerant therefore used in most of the Space application. AMBA Bus is used to interface the on chip peripheral with processor. This project report covers the theory of the SpacWire Protocol, its simulation work, theory of LEON processor, implementation of LEON3 core and AMBA AHB interface on Virtex 4 FPGA board and testing of LEON3 based SoC design.
