Abstract

In recent years the complexity of space- oriented applications has grown dramatically. The amount of processing utilized in spacecrafts has increased. The data rates and volumes produced by both scientific and commercial space missions have increased significantly thus creating an urgent need for better processors. For space applications, high performance and high reliability are the most major issues that become more and more important. Satellites are expensive, computers are unreliable and if failing they will risk the mission. Past space computers were expensive and hard to get, hence the drive to make space computers based on COTS. This paper surveys various approaches to space processors and offers some recommendations. An analysis and survey has been done on various processors regarding radiation hardened, fault tolerant, low power, high performance and also comparison has been done for that processors. Empowered with the analysis of past the future research roadmap is proposed.
