This paper proposes a new systolic array architecture to perform division operations over GF(2 m ) based on the modified Stein's algorithm. The systolic structure is extracted by applying a regular approach to the division algorithm. This approach starts by obtaining the dependency graph for the intended algorithm and assigning a time value to each node in the dependency graph using a scheduling function and ends by projecting several nodes of the dependency graph to a processing element to constitute the systolic array. The obtained design structure has the advantage of reducing the number of flip-flops required to store the intermediate variables of the algorithm and hence reduces the total gate counts to a large extent compared to the other related designs. The analytical results show that the proposed design outperforms the related designs in terms of area (at least 32% reduction in area) and speed (at least 60% reduction in the total computation time) and has the lowest AT complexity that ranges from 80% to 94%.
An Electro4hermally and vertically driven MEMS actuator is analytically and practically examined which is based on the asymmetrical thermal expansion of the mictrostructnre with the different shape of its beam. Analytical results are presented and conpared with results obtained from finite element modeling (FEM). In previous work we introduced the use of such thermal actuator in micropositioning application to drive a variable capacitor as a part of an RF circuit. In this paper, issues related to the optimal design of the microstructure of the actuator are presented with its effect on the performance of the system, which lead to an improved design.
