| () |
| Abstract: |
| Based on the theory of polynomial multiplications in Galois field, an 8-bit fast multiplier in (GF(2~8)) is designed using the higher hierarchy technique, and the VHDL model of the multiplier is presented. The design process such as VHDL entry, functional simulation , place and route, timing simulation and device programming are performed by using the XILINX Foundation Series 3.1i software .The circuit is verified in the XC9572PC84 programmable logic device .The circuit for computing multiplications can be used in RS(255,223) codecs. |
