Flexible and Distributed Real-Time Control on a 4G

Abstract Applications like 4G baseband modem require single-chip implementation to meet the integration and power consumption requirements. These applications demand a high computing performance with real-time constraints, low-power consumption and low cost. With the rapid evolution of tele-com standards and the increasing demand for multi-standard products, the need for exible baseband solutions is growing. The concept of Multi-Processor System-on-Chip (MPSoC) is well adapted to enable hardware reuse between products and between multiple wireless standards in the same device. Based on the experience of two heterogeneous Software Dened Radio (SDR) telecom chipsets, this paper presents a distributed control architecture for the homoGENEous Processor arraY (GENEPY) platform for 4G applications. This MPSoC platform is built with telecom baseband processors intercon-nected with a Network-on-Chip. The control is performed by a MIPS processor embedded in each baseband processor. This control processor can locally recongure and schedule the appli-cations with real-time telecom constraints. I
