QAM is a widely used multilevel modulation technique with a variety of applications in data radio communication systems. Most existing implementations of QAM-based systems use high levels of modulation in order to meet the high data rate constraints of emerging applications. This work presents the architecture of a highly parallel QAM modulator using MPSoC-based design flow and design methodology which offers multirate modulation. The proposed MPSoC architecture is modular and provides dynamic reconfiguration of the QAM utilizing on-chip interconnection networks offering high data rates more than 1 Gbps even at low modulation levels 16-QAM . Furthermore the proposed QAM implementation integrates a hardware-based resource allocation algorithm that can provide better throughput and fault tolerance depending on the on-chip interconnection network congestion and run-time faults. Preliminary results from this work have been published in the Proceedings of the 18th IEEE IFIP International Conference on VLSI and System-on-Chip VLSI-SoC 2010 . The current version of the work includes a detailed description
