Weekly Group Meeting Project: Software Defined Radio Development using Network-On-Chip based Rapid Prototyping Platform By Assad Saleem

2 Agenda B-2 Development Methodology

3 Development Methodology Many options to implement the SDR The option we‘ll pursue is the : “NOC based prototyping platform that integrate highly reconfigurable Kernels” Figure-8: Architectural options to implement the SDR

4 Development Methodology Research Contents a)Analysis of the Application Domains and definition of kernels, b)Defining and architecting the REXAPP architecture and the kernels, and c)The methodology for mapping applications to the REXAPP architecture.

5 Development Methodology a)Application Domains (AD) “Sets of sequences of signal processing transformations that have a high degree of commonality in their functionality but not necessarily in their dimension” -Radio access methods (TDMA, CDMA, OFDM), modeling of impairments in RF front end, PA linearization, Channel Modeling, Smart Antenna Engineering, MIMO Systems, Cognitive Radio -Our Focus: 4G, and Smart Antennas technologies as proof of concepts Kernels “Realization of above mentioned transformations”

6 Development Methodology Kernels -primary building blocks -not the optimal choice to cover an entire AD -such parts that are hard to realize as a reconfigurable kernel will be realized by arbitrary algorithms using secondary building blocks like FPGAs or ASIPs

7 Development Methodology b) REXAPP architecture and Kernels -Reconfigurability & scalability of kernels => able to host widely varying requirements of transformations in a Domain -If this is not possible using one kernel => define more than one to cover the breadth of variations

8 Development Methodology b) REXAPP architecture and Kernels Figure-9(a): Conceptual view of a NOC tile

9 Development Methodology b) REXAPP architecture and Kernels Figure 9(b): An example REXAPP System

10 Development Methodology REXAPP Complier: This is the principal component that will be developed in this project –It’ll have access to a database of Kernels and NOC templates –Database format and the Kernels will be developed within this project –NOC template has been developed at KTH and continues to evolve and is not part of this project.

11 Development Methodology Kernels and NOC Templates Database: –Exact format will be decided during execution phase –Plan to use existing XML based international standards like SPIRIT –For efficiency, these XML based representations are very likely to be translated to binary format

12 Development Methodology c) REXAPP methodology flow Figure-10: REXAPP Methodology Flow

13 Development Methodology REXAPP Complier: will generate three outputs 1.An RTL model meant for logic synthesis followed by physical synthesis => to generate the actual physical design in GDSII format 2.Transaction level model => fast and efficient simulation to compare the functional properties of NOC based implementation against the original Matlab model 3.Cycle accurate simulation model => accurate performance measures with back-annotation from the detailed physical design => to do detailed timing analysis to check the performance and possible fine tune the architecture and mapping policies

Thank You.
