2 Agenda Introduction to OpenCPI Comparisons to Existing Frameworks Motivation for GRC Integration OpenCPI and GRC (Demo) Road Map for Future Development How to Get More Information

3 Introduction to OpenCPI Open Component Portability Infrastructure Component-based framework for developing portable processing applications targeting various processing technologies Processing technologies can include multiple field programmable gate arrays (FPGAs), general purpose processors (GPPs), graphical processing units (GPUs)*, and a variety of interconnection technologies Designed to be platform agnostic and easily adaptable to new platforms Integrates existing tools for FPGA development such as ISE, Vivado, Sim/ISim, ModelSim, Quartus II, etc. *in development/coming soon

4 Introduction to OpenCPI T DSP library GPP RF Chain CTRL OpenCPI Util library R D/A A/DCTRL OpenCPI OpenCPI FPGA Misc library Clock, Timing, Portable, reusable components are developed in native language for the final target platform (i.e. VHDL/C++) independent of intended application Applications are constructed from existing components Application deploys to target platform, with components executing on disparate parts of platform

5 OpenCPI Applications and Components Application A collection of interconnected component specs Component 1 Component 3 Component A specification of a function or operation implemented by Workers to run on specific platforms Component 2 Component 4 Component 5 Component 6 Worker A concrete implementation of a component

6 OpenCPI Containers and Assemblies Container A Container C Component 1 Container B Component 3 Component 2 Container D Component 4 Container E Component 5 Component 6 Container Execution environment that runs on some platform that executes workers

7 OpenCPI - s Container A Container C Component 1 Container B Component 3 Component 2 GPP/x86 GPU Container D Container E Component 4 GPP/ARM Component 5 Component 6 FPGA Physical device which houses one or more interconnected Containers and associated I/O

8 OpenCPI - s Container A Container C Component 1 Container B Component 3 Component 2 GPP/x86 GPU Container D Container E Component 4 GPP/ARM Component 5 Component 6 FPGA Assembly Collocated subset of an application built from one or more HDL workers

9 OpenCPI Interconnect/Bus/Network & I/O C&C I/O Container A Container C Interconnect/Bus/ Network & I/O Physical connections between s that is typically abstracted away from the developer Component 1 Component 3 Container B Component 2 GPP/x86 TCP/IP GPS I/O I/B/N GPU PCI Express Interconnect/Bus/Network Container D Container E AI I/B/N Component 4 GPP/ARM Component 5 Component 6 FPGA DAC I/O

10 OpenCPI OpenCPI System OpenCPI System C&C I/O Container A Container C System A collection of interconnected OpenCPI-enabled s that can be used to execute Applications Component 1 Component 3 Container B Component 2 GPP/x86 TCP/IP GPS I/O I/B/N GPU PCI Express Interconnect/Bus/Network Container D Container E AI I/B/N Component 4 GPP/ARM Component 5 Component 6 FPGA DAC I/O

11 Comparisons to Existing Frameworks GNU Radio RF NoC OpenCL REDHAWK OpenCPI FPGA Support Supported with vendor specific extensions Treats FPGA as black box Access FPGA I/O (ADC/DAC) Software Support GPU Support Planned for future release Agnostic Leverages Native Language Distributed Support for distributed processing across embedded targets planned for future release

12 Motivation for GRC Integration Provide a front end GUI for the OpenCPI Application Developer to quickly test, design, and run OpenCPI Applications or Assemblies Mostly work currently done by hand Leverage the existing work that was done in GRC that does not fall within OpenCPI's domain Introduce OpenCPI to the GNU Radio community in a way that is familiar and easy to use Enhance GRC to be able to run certain blocks on various hardware platforms such as FPGAs, GPPs, GPUs, etc

13 OpenCPI and GRC General Outline Install OpenCPI and build the assets for the desired platforms (Optional) Write and build your own OpenCPI workers specific to your application OpenCPI Documentation Run ocpigr to import the workers into GRC as GRC blocks Create flowgraph as you normally would with vanilla GRC Set the deployment to target the desired containers for each block Build/Run the application Covered in this presentation

14 OpenCPI and GRC ocpigr Tool Tool in the OpenCPI repo that will parse all OpenCPI workers/components found in the OCPI_LIBRARY_PATH and translate their ML into GRC block xml Creates an OpenCPI Container block for each platform that was encountered during parsing Takes advantage of the GRC Domain concept by making a domain for each encountered during parsing

15 OpenCPI and GRC ocpigr Tool The The ocpigr ocpigr tool tool imported imported the the OpenCPI OpenCPI Component Component Specs Specs under under the the OpenCPI OpenCPI Block Block Tree Tree

16 OpenCPI and GRC Creating a Flowgraph OpenCPI OpenCPI blocks blocks can can be be used to create a flow used to create a flow graph graph just just as as you you would would with GNURadio Blocks with GNURadio Blocks

17 OpenCPI and GRC Running a Flowgraph A A valid valid flowgraph flowgraph can can then then be be generated generated into into an an OpenCPI OpenCPI project project and and run run using using the the standard standard GRC GRC buttons buttons

18 OpenCPI and GRC Running a Flowgraph OpenCPI OpenCPI provides provides deployment deployment logic if a deployment logic if a deployment (association (association of of where where to to run run the the components components of of an an algorithm) algorithm) isn't isn't specified specified

19 OpenCPI and GRC Running a Flowgraph GRC GRC will will autodetect autodetect OpenCPI OpenCPI blocks blocks and and use use the appropriate generate the appropriate generate and and run run options options A A valid valid flowgraph flowgraph can can then be generated then be generated into into an OpenCPI project an OpenCPI project and and ran ran

20 OpenCPI and GRC Set Deployment Each Each GRC GRC block block has has a a Container Property which Container Property which dictates dictates on on which which container container in in the targeted system the block the targeted system the block should should execute execute

21 OpenCPI and GRC Set Deployment Different Different containers containers are are represented represented visually visually with with different different colors colors (via (via GRC GRC Domains) Domains)

22 OpenCPI and GRC Build Assembly When When Targeting Targeting Containers Containers that that require require Artifacts Artifacts that that need need to to be be built built (ex. (ex. HDL HDL bit bit file), file), the the build build button button becomes becomes active active and and will will orchestrate orchestrate the the project project generation generation and and building building for for you you

23 OpenCPI and GRC Set Deployment To To move move from from a a simulation simulation environment environment to to actual actual hardware, hardware, simply simply select select a a different different deployment deployment for for the the intended intended target target

24 OpenCPI and GRC Set Deployment Example Example worker worker that that was was built built for for multiple multiple platforms platforms

25 OpenCPI and GRC Example BFSK App Example Example of of a a BFSK BFSK OpenCPI OpenCPI application which is writing application which is writing to to a a named named pipe/fifo pipe/fifo on on the the local local filesystem filesystem

26 OpenCPI and GRC Example BFSK App This This allows allows GRC GRC to to read read from from the the named named pipe pipe real real time time to to either either do do further further processing processing or or verification verification of of current current the the processing processing chain chain

27 OpenCPI and GRC Example BFSK App This This flowgraph flowgraph implements implements the the R/demod portion of the app R/demod portion of the app to to verify verify the the T T is is operating operating correctly correctly

28 OpenCPI and GRC Example BFSK App If If everything everything looks looks good, good, switch switch deployments deployments to to a a different different target target to to build build and and run run on on actual actual hardware. hardware. Building Building is is only only necessary necessary ifif the the assembly assembly is is not not already already built. built.

29 Road Map for Future Development Have GRC and OpenCPI blocks talk directly or through a translation block Enable GRC to determine if the required artifacts are available and automatically build them if they are not Expose more features of OpenCPI to the GRC user Select specific worker Customize HDL Container Allow deployment across multiple systems on a network OpenCL/GPU support Support more platforms out of the box
