An implementation of global/local feedback system on 2.5 GeV SIBERIA-2 storage ring is reported. This project based on parallel data handling in BPM modules and VME crate for communication and magnet correction control. We present special own-made beam position monitor data acquisition module, which includes ADC, DSP TMS32030 and high-speed serial link. Paper describes software for simulation of feedback control and digital filtration. The motivation, approaches, results and future directions of this project are discussed.
