Automotive MRD Overview

Developing Multicore Software is Easy, If…

Freescale Technical Forum - Summer 2009

Emeka Nwafor Director, Product Management Development Tools

Multicore is here. There has been much written and discussed about how challenging developing Multicore Software can be. Most of us have heard the saying "you shouldn't bring a knife to a gunfight". This principle applies to developing Multicore Software. We will talk about how Wind River's development tools help to make developing Multicore Software easier on Freescale's family of multicore processors. We will also talk about directions that Wind River is taking to make developing Multicore Software "easy".

 Context: Where are we with multicore, today?

 What is Wind River's Multicore Software solution?

 Simplifying development on Freescale's multicore devices

 Directions for Multicore Software

18% Increase in dual-processor based designs since 2006

42% Percentage of embedded developers that say that chip technology will represent the most dramatic area change in embedded software development over the next 2-5 years

34% Percentage of embedded developers saying that embedded development / design processes will change significantly in the next 2-5 years 84% State that in-house code from previous projects is reused in new projects

“We found that things were obscenely sensitive while we were trying to optimize the usage of our cache…”

“It is very easy to write a slow multicore application and very hard to figure why it is slow.”

“Software Engineers didn’t ask for multicore – it was forced on them…”

“We are absolutely terrified about multicore and the challenges that parallelism and concurrency are introducing. We saw it coming, it just arrived faster than we anticipated…” 5

System/Device Architecture: Application Architecture: New technologies require new system What is the best approach to meet architectures design goals?

• What us the best or most appropriate • Reuse of software – is the configuration – SMP or AMP? existing application suitable? • Partitioning and Offloading? • Is my middleware suitable? • Fault Isolation and What new skills, • Optimize for what? Recovery processes and (Performance, re-use, TTM, …) tools does my Business Goals: team need? Software Development How do I balance my market and Test: goals with my business constraints? What do I need to consider for multicore? • Low product cost – purchase and operational • Software development lifecycle • Innovation versus quality versus TTM • New skills and tools • Performance versus power consumption “Time tested process in doubt?” • Certification? • Debug multicore applications?

• Wind River began porting VxWorks to the P4080 architecture 18 months prior to P4080 silicon availability

• Within 2 months of receiving the Simics P4080 Virtual Platform, Wind River was able to demo VxWorks running on the P4080

• Used it to develop VxWorks SMP and Wind River Hypervisor

• Used it to debug & test multi-core aspects of VxWorks and Hypervisor – Leveraged reverse execution – Leveraged checkpointing – Leveraged visibility and control of internal device states – Leveraged ability to stretch/compress virtual time to force abnormal timing conditions
