Designing efficient task mapping methods to transmit and process task data under multiple constraints is challenging. Existing works seldom consider the joint design problem under timing, energy, and reliability constraints, which are coupled with each other, introducing complexity in designing efficient task mapping methods. In this paper, we first formulate the joint design problem as a complex combinational optimization problem and design a linearization method to find the optimal solution. To reduce computation complexity and enhance scalability, we design a decomposition-based heuristic method.
