With the advent of heterogeneous MPSoC platform architecture based implementations for the IEEE 802.11n PHY processing, system partitioning and assignment (P&A) have become a key challenge. In this paper we have analyzed the area and energy trade-offs across different P&A schemes for the 4x4 and the 2x2 MIMO 40MHz modes of 802.11n. We have considered the payload processing part of the inner-modem processing for 802.11n PHY. We also present a framework for systematically carrying out the P&A exploration. We show that by exploiting parallelism at different levels, the energy can be reduced with negligible area overheads, by about 40% and 15% for the 4x4 and 2x2 modes, respectively. We also show that the P&A schemes with fine-grained partitioning are more energy efficient for mapping both the modes together on the same platform.
