Implementation of W-CDMA Cell Search on a Highly Parallel and Scalable MPSoC

Abstract

The performance of the W-CDMA cell search algorithm can be significantly improved using homogeneous general purpose Multi-Processor System-on-Chip (MPSoC) architectures. The application also scales well, as the number of processing nodes increases, allowing practical accelerations to become close to the theoretical maximum. In this work we describe a template MPSoC architecture based on multiprocessor computational clusters, called Ninesilica. Each Ninesilica consist of nine processing nodes based on COFFEE RISC architecture. MPSoC inter-and intra-cluster communication are enabled using hierarchical Network-on-Chip with dedicated point to point and broadcast communication services for better performance. Proposed template has been used to instantiate complete systems with one and four Ninesilica clusters, resulting in MPSoCs with respectively 9 and 36 computational nodes. The MPSoCs have been physically prototyped on a FPGA device, and the W-CDMA cell search algorithm has been mapped on both MPSoC platforms. The four Ninesilica MPSoC can execute

Versatile digital architecture for mobile terminal

“…Therefore, a specific generic architecture can be performed if we interconnect several modules of the proposed common operator (in a pipeline or parallel form) with memory blocks [37,38]. However, opposite to use memory crossbar and configurable switching control to manage data paths [10], we opt to use a very flexible memory that virtually connects the proposed common operator.…”

FPGA Prototyping and Design Evaluation of a NoC-Based MPSoC

“…Different NoCs solutions are used in MPSoC platforms and commercialized by many companies such as SonicsGN [5] developed by Sonics, FlexNoC [6] by Arteris, AEthereal NoC [7] by Philips Research Laboratories and Teraflops Research Chip (also called Polaris) [8,9] by Intel Corporation's TeraScale Computing Research Program. Other NoC-based multicore system architectures are developed by teams from universities and research institutions such as SoCIN [10], OCCN [11], FAUST [12] and Ninesilica [13].…”
