“…BM3803 is an anti-radiation 32-bit RISC embedded processor based on SPARC V8 architecture. Its anti-radiation performance is superior, the total dose anti-radiation capability is 100krad (Si), the single particle locking threshold is better than 75MeV•cm2/mg, and the on-orbit error rate is better than 3E-5 times/device /day [1] . It has complete three-mode redundancy design, EDAC and parity check fault tolerance, and on-chip memory controller supporting PROM, SRAM, SDRAM and I/O mapping space access, meeting the needs of long-term on-orbit use [2] .…”

In order to improve the adaptability and maintainability of a certain type of servo controller in the space environment, BM3803 has three-mode redundancy, EDAC and parity check fault tolerance design, which can meet the requirements of radiation resistance, long life and high reliability in harsh space environment applications. Therefore, an on-orbit reconstruction method of on-board CPU software based on BM3803 processor is proposed based on this project. In this method, the up-coding program block sent by the integrated processor is received through RS485 bus, and the up-coding program is stored and run by partitioning EEPROM and SRAM. Multiple verification of the receiving process, improve the reliability of the file upload process; The packet serial number, packet check and total check are transmitted down by telemetry to realize effective monitoring of the up-filling process. The load switching between the original program and the reconfigured program is realized by the combination of recharging load and sending instruction. Through testing, the correctness, rationality and reliability of the scheme are verified. At present, the scheme has been applied in orbit.
