Abstract Cyclic codes over the ring R=Fpm+uFpm can be seen as the ideals of R[x]/<xpk-1>. Based on the studing of ideals of R[x]/<xpk-1>, a unique method of representing cyclic codes of length pk and their mass formulas over the ring Fpm+uFpm are provided. For the cyclic self-dual codes of length pk over the ring Fpm+uFpm, their structures and mass formulas are given.
