To meet the future demands of earth observation satellites
this paper presents a novel architecture and describe the implementation of a prototype named Space Solid-State Recorder with several Memory Modules (MMs) connected by high-speed serial links.The MM utilizes an FPGA and DDR SDRAM to boost throughput
and adopts a featured SDDA (Single-Data-bus
Double-Address-bus) storage topology to manage and control these memory chips efficiently.Through high-speed serial transceivers embedded in the FPGA chip
several MMs interconnect with each other to form the Space Solid-State Recorder.To ensure the quality of serial links
a multilayer communication interface protocol stack that consists of a physical layer
link layer and message layer is proposed.As a result
the MM can provide storage capacity of 8GB
and its memory bandwidth approache
s 3.2GBps.Furthermore
the physical bandwidth of the communication interface can reach up to 25Gbps.Moreover
the bit error rate (BER) of the interface in Space Solid-State Recorder system is below 10
