  18. SLD Working Group Update Mark Burton (Windriver), November 10, 2011

  19. Short term: minimal release • Revive group • Short term goal – new release of adapters • Big goal of the release is to effectively announce “We are working again”: Generate involvement • Note: One interpretation is that there isn’t that much burningly wrong with the kit, which is why there has been less interest in tweaking bugs! 19

  20. Mid term: IPXACT and EDA Compatibility Both IPXACT and EDA compatibility remain extremely valuable subjects. EVE involved in SLD WG now, and already expressing interest to ensure compatibility. Other EDA’s making positive noises again. Will plan mid term around end of year. 20

  21. GSC ‘goals’ need revisiting Given the status of the group, we need to revisit the goals set by the GSC. Goal one: make a release and trigger involvement. Goal two: report in the next GSC what the EDA compatibility/IPXACT plans are. 21

  22. The SLD Mid-Term Vision - unchanged NO JOKE - our kit IS high quality, and that is maybe the problem – it is rather too stable! OUR KIT IS HIGH QUALITY, AND STABLE.. Ensure that OCP users have a 'complete' modelling infrastructure available multiple levels of abstraction (pure-functional to cycle-accurate) and use models (software development, architecture exploration, etc) completeness means bus interface, performance monitoring interface ,system debug interface and configuration interface Make this modelling infrastructure standards compliant. E.g. drive existing OCP-IP experience and expertise into OSCI-TLM Maintain alignment between OSCI-TLM OCP-IP

  41. 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. 41

  42. 42

  43. 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)‏ 43

  45. Specification WG Update Drew Wingard(Sonics Inc), November 10, 2011

  46. Specification WG 2011 Plan Status

  47. Specification WG Issues • Cache coherence extensions • Some motivation forming for CoreCreator • Barrier extension revision agreed! • Two flavors complex/simple • Performance counting parameters agreed • Vesa committed to do consensus profile update • Drew just found & replied to Q’s from Sept. end • Bug/typo processing improved • Active attendance: MIPS, Renesas, TI, Sonics

  48. OCP 3.1 Drafting • SpecWG Dependencies • Need to review FVWG Coherence protocol checks • Have MDWG contribution • Spec WG components progressing… • Estimate ready end Nov. • FVWG Dependencies • Need to review 3.1 proposals • MDWG Dependencies • Need 3.0 and 3.1 extension coverage • We can engage tech writer now • But need to keep him/her fed…

  49. 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
