Multi-core architectures are increasingly being adopted in the design of emerging complex embedded systems. Key issues of designing such systems are on-chip interconnects, memory architecture, and task mapping and scheduling. This paper presents an integer linear programming formulation for the task mapping and scheduling problem. The technique incorporates profiling-driven loop level task partitioning, task transformations, functional pipelining, and memory architecture aware data mapping to reduce system execution time. Experiments are conducted to evaluate the technique by implementing a series of DSP applications on several multi-core architectures based on dynamically reconfigurable processor cores.
