Abstract: In this paper, a heterogeneous multi-core SoC is modeled and analyzed, and the implementation problem of LT code’ (Luby Transform code) encoding on a heterogeneous multi-core SoC is transformed into a mapping problem of LT code encoding subtasks on the heterogeneous multi-core SoC, Besides, a task mapping method based on genetic algorithm is given. Finally, the encoder is implemented on the heterogeneous multi-core SoC based on Xilinx ZYNQ-7000. Experimental results show that the Experimental results show that the designed LT code encoder can adapt to different performance and resource requirements, increasing the practicability of the hardware platform and the flexibility of application system design.

Key words: heterogeneous multicore, ZYNQ, Luby transform code, hardware implementation technology
