【Abstract】 In this paper, some basic concepts on RS code are narrated briefly, and then the essence encoder flow on RS(255,239) based on multiplication and addition in Galois Field is introduced in depth. Furthermore, the verification platform employing VHDL code is structured, the circuit function and timing is verified by using QuartusⅡ,the results of simulation and synthesis are given and the FPGA download is completed at the end of thesis.更多还原
