Abstract :
A programmable system platform that enables software defined implementations of WCDMA and OFDM baseband receivers is presented. The design complexity of future wireless terminals and the shrinking time-to-market constraints are the motivators for adopting the platform-based design methodology. The presented hardware platform comprises a RISC core and three tightly coupled coprocessors that are used for the most intensive computation kernels. The application program interface of the platform is provided in the form of a library of special C-functions that are used to pass the input parameters to the coprocessors and initiate the execution. The SystemC-based simulation environment of the platform is described and the simulation results are given.
