  In order to further meet the needs of major national strategies and basic scientific research, High Energy Photon Source (HEPS) will be a high-performance fourth-generation synchrotron radiation source in Beijing, which will build more than 90 high-performance beamline stations. In order to ensure the high-performance operation of each beam line, the stability of the beam orbit near the light source output point is extremely important. As one of the key guarantees for the stability of the electron beam orbit, The FOFB system can suppress the beam orbit disturbance within a certain bandwidth to an acceptable range. This article introduces the currently progress of the FOFB system, including: the overall architecture scheme and key technical routes; the substation design following the ATCA mechanical architecture; the BPM data acquisition and high-speed transmission using high-performance Rocket I/O transmission Mechanism; embedded high-performance DSP for fast multiplication calculation to realize SVD, etc. The entire system design is progressing in an orderly manner.
