SDR enables cost-effective multi-mode terminals but still suffers from significant energy penalty when compared to dedicated hardware solutions. At system level, this energy bottleneck can be leveraged capitalizing on heterogeneous MPSoC platforms where specific engines are dedicated to classes of functions with similar computation characteristics and duty cycle. In burst-based communication as in IEEE802.11 or IEEE802.16, burst detection functions have high duty cycle and hence need an ultra low power implementation. Besides, programmability must be preserved to support multiple modes.
