Abstract

In this paper, we present a flexible and distributed homogeneous Software Defined Radio (SDR) platform. This platform is an array of processing elements, called Smart ModEm Processors (SMEP), interconnected by a Network-on-Chip. Implemented in ST65nm, each processing element performs 3.2 GMAC/s with 77 GBits/s internal bandwidth while dissipating 110mW. Each SMEP unit contains a MIPS processor for task management including dynamic mapping. This distributed management solves the MPSoC scalability and programmability problem, and improves resource allocation and energy efficiency. This homogeneous approach with high management flexibility is new in the domain of mobile terminals. With real-time constraints, the challenge is to enables flexibility with a reduced overhead in terms of performance, power consumption and silicon area.
