Abstract

The European Space Agency (ESA) recently proposed the space wire standard for reliable satellite on-board networking at high speeds. This paper presents the design of configurable space wire router and interface hardware macrocells, the first in state-of-the-art compliant with the latest standard extensions, protocol identification and remote memory access protocol. The space wire router with 8 links achieves 100 Mbits/s data rate with 135 W power consumption and 300 Krad radiation tolerance. These performances meet the requirements of planned ESA space missions
