This paper is devoted to the application of specialized processors for speeding-up the realization of relational algebra operations on fine-grain SIMD computers. A short description of two processors is presented. By means of a special high level language STAR, the algorithms of implementation of relational algebra operations in a STARAN-like computer model are described. Then the representation of the same algorithms is considered for the same model with attached processors. The comparison is made, corroborating the efficiency of the proposed co-processors.
