This paper introduces a Data processing scheme of MIMO indoor visible light communication sys-tem based on TI's floating point DSP TMS320F28335. Its characteristic is to use Direct Memory Access abili-ty of TMS320F28335 to achieve data transmission. This method can satisfy the requirements for high-speed data transmission in real-time signal processing and also makes the data processing take less resource from DSP CPU, which saves the running time of the whole system greatly. The experimental results show that the accuracy and reliability of this Data processing scheme are both well. It overcomes the negative influence of the channel crosstalk and then makes sure the data of system can be recovered in real-time.
