Abstract—This paper primarily introduces a novel architecture for spaceborne intelligent computing and intelligent data processing. By leveraging the collaborative operation of a High-Reliability Computer (HRC) and a High-Performance Computer (HPC), this architecture achieves both highly reliable payload management and data interaction, as well as high-performance intelligent computing and data processing objectives within the space application environment. Specifically, the HRC is responsible for data interaction with the spacecraft bus, encompassing telemetry and telecommand (TT&C) information for various payloads, along with temporal and spatial information. The HPC, conversely, is primarily tasked with executing application software (apps) to process received payload data. This includes computation-intensive tasks such as attitude and orbit determination. Communication between the HRC and HPC is facilitated via a high-reliability Field-Programmable Gate Array (FPGA). This FPGA collects the status and science data from different payloads through interface chips and stores them in mass memory. Following data retrieval as required, the system transmits the acquired information to the corresponding computing module (HRC/HPC) to perform its designated operational functions.
