Optimization of automatically generated multi-core code for the LTE RACH-PD algorithm

Résumé

Embedded real-time applications in communication systems require high processing power. Manual scheduling devel-oped for single-processor applications is not suited to multi-core architectures. The Algorithm Architecture Matching (AAM) methodology optimizes static application implementation on multi-core architectures. The Random Access Channel Preamble Detection (RACH-PD) is an algorithm for non-synchronized access of Long Term Evolu-tion (LTE) wireless networks. LTE aims to improve the spectral efficiency of the next generation cellular system. This paper de-scribes a complete methodology for implementing the RACH-PD. AAM prototyping is applied to the RACH-PD which is modelled as a Synchronous DataFlow graph (SDF). An efficient implemen-tation of the algorithm onto a multi-core DSP, the TI C6487, is then explained. Benchmarks for the solution are given.
