摘要
In the remote upgrade of digital signal processing (DSP) control program of fast control power supply for plasma vertical displacement on EAST, a new second-level boot structure is proposed by changing the sequential structure of the second-level boot . This structure does not require the involvement of assembly language and uses C language to write the second-level boot program. The structure is also combined with wireless network transmission technology to enable remote upgrading and curing of the program. The experimental results show that the proposed second-level boot structure combined with the wireless network is capable of cryptographically upgrading the control power DSP program remotely. ? 2022 Yuan Zi Neng Chuban She.
