  9. Meta Data WG Update Prashant Karandikar(Texas Instruments), February 23, 2012

  10. Metadata WG Status

  11. Spirit Enhancement Propose and drive modifications into IP-XACT standard Provide OCP Bus definition/Abstraction Definition Standard Extension/Schema change ( Q1 2011 through Q4 2011 ) Status : Provided OCP Bus definition/Abstraction Definition reference from OCP-IP website to David Murray (Duolog) Chair of User’s Group responsible for collecting abstraction/bus definitions. OCP-IP requirement for support for configurable bus interfaces has been accepted for PSS. OCP-IP requirement is binned along with other conditional elements like conditional instances ( and many more conditional elements in component/design ) New Accellera IP-XACT PSS are yet to come for voting, It would be followed by a validation phase which is likely to continue till Q1 2013 11

  12. Core Compatibility report rtl.conf  IP-XACT conversion & Release to OCP-IP members ( Q1 2011 ) Status rtl.conf  IP-XACT ( legacy support ) has been created. Planning to release the converter along with OCP3.0 checker enhacement. 12

  13. IP-XACT Enhacement Enhance for OCP IP-XACT checkers for OCP 3.0 Status OCP3.0 busdef/absdef are under review Awaiting for cache coherency rules enhancement Provided feedback to FVWG on the config rules. Implement Extensions for TLM2 Status Yet to start on this activity TLM2 modifications in new IP-XACT schema is still under discussion. 13

  15. SLD Working Group Update Mark Burton (Windriver), February 23, 2012

  16. SLD WG Status

  17. Status and plans Over the last 12 months, we have had very very little resource (effectively zero) We have JUST enough resource to do a release – we’re already 2 months later on that than we expected. We believe we will have JUST enough resource to do a compatibility release with the new SystemC 2.3 this year. We will then aim to show a commercial tool compatibility matrix. – we will look for support from tool companies. (e.g. compile, and report – we believe some of the tools will work out of the box, but some will have issues, we aim to show which tools work with SystemC 2.3, TLM 2.1 and the OCPIP kit). MDWG interaction James and Mark will contribute We envisage no other activity! 17

  20. Recent activites (1): TG + MCSL • TG can now execute also MCSL application models • MCSL benchmark suite was developed at Hong Kong University of Science and Technology • They also joined the workgroup recently • http://www.ece.ust.hk/~eexu/index_files/benchmark.htm • Data-flow models for 8 applications • Both recorded and statistical models • TG-specific constraints given in separate XML file • Available on TUT site currently 20

  21. Recent : TG + MCSL example Table: [Weichen Liu, Jiang Xu, Xiaowen Wu, Yaoyao Ye, Xuan Wang, Wei Zhang, Mahdi Nikdast, Zhehui Wang, “A NoC Traffic Suite Based on Real Applications,” IEEE Computer Society Annual Symposium on VLSI (ISVLSI), July 2011. Available: http://www.ece.ust.hk/~eexu/publications/ISVLSI2011_Benchmark.pdf] ./sctg.exe -i examples/sparse_mesh_8x8.stp -c examples/constraints.xml Transaction Generator input-file: examples/sparse_mesh_8x8.stp Delay for playback: 1ms Directory to save logs: . cpu0: int (1) float (1) mem (1) . . .

  37. Evolution of Multi-Core Debugging and Link to OCP OCP Debug WG GOAL: Commercially available multi-core debug IP-blocks for the OCP interconnect MCDS debug IP takes 12 man months to adapt to a new processor core. Biggest obstacle is the wide variability of the debug interfaces in the processors. We plan to classify processors according to debug interface functionality: Single threaded, multi threaded, outstanding transactions, out of order, cache coherency transactions, … require different debug activities. And absolutely nice would be to see somebody using it with success. 37

  38. 38

  39. Summary Main target philosophy is: Debug N cores on a chip by selecting any 2 or more cores for a time-aligned comparative debug session. OCP-IP has standardized a Debug Interface between system bus and multiple processor cores and IP-blocks in a SoC design. • It enables reusable multi-core Debug-Hardware solutions. (OCP/JTAG/Nexus/MIPI)‏ • It promotes Debug-Software for multiple cores in one GUI. (See SPRINT debug APIs)‏ • This shall create the market for SoC designers for reuse of verified multi-core debug-IP solutions. (See IP-Extreme, HDL-Dynamics, Temento, ... IP providers)‏ 39

  41. Specification WG Update Drew Wingard(Sonics Inc), February 23, 2012

  42. Specification WG 2011 Plan Status 42

  43. Specification WG Issues Cache coherence extensions Synopsys part of CoreCreator proceeding well Barrier extension text finalized And distributed to other WGs Waiting on FVWG for compliance checks for performance counting parameters Renesas Mobile and TI provided consensus profile updates Need to resolve some issues Bug/typo processing improved Need to move meeting date/time to ease participation 43

  44. Summary from Tech Writer Not in 3.1 During Member Review 44

  45. OCP 4.0 Concept Add support for serialized (packet-like) interfaces while maintaining higher level semantic of OCP Will likely be peer-to-peer (rather than master/slave) Should be attractive in networking/communications, especially via FPGA Should also consider how TSV interconnections change opportunity/attractiveness However Have not yet been successful at attracting new members to help drive the work 45

  47. Technical Vision WG Status / Restated Ian Mackintosh(OCP-IP), February 23, 2012

  48. Technical Vision WG Status Restated (Ian) • OCP-IP offering was fully defined as prioritized “whole product” at February 23, 2012 TVWG meeting • 2012 priorities were agreed by TVWG and will be disseminated to all WGs for ratification and scheduling - all recommendations will be reduced to agreed goals and and will be tracked as overall OCP-IP 2012 objectives • There have been nodeliverablesmade available through WGs since last GSC meeting • Memory Model / Traffic Patterns / TG combination release was released just prior to last GSC meeting in November • There are several IMPORTANT deliverables from the WGs in the pipeline • OCP 3.1 • Debug Spec Version 2.0 • OCP 3.0 Checks and Assertions (Compliance document) • OCP Tracker / Conductor available on Xuropa for demos • AMBA LUT • CoreAssembler • January 2012 TVWG Session focused on adding new deliverables and tuning-up schedules on current WIP. We still need to ensure we have clear and complete schedules for deliverables requested of the working groups • We need to take an AI to incorporate Ais for yesterday’s TVWG into the General GSC AI sheet. We also need to issue brief minutes for yesterday’s TVWG session in tandem with these set of GSC minutes • 2012 TVWG session is now complete.
