  • 4. Embedded Multicore  Designs using multiple cores are becoming common – multiple cores on a chip – multiple chips on a board – any combination  Two hardware architectures: – homogenous – multiple identical cores – heterogeneous – multiple cores of different types  Broadly two software architectures: – SMP – Symmetrical MultiProcessing – AMP – Asymmetrical MultiProcessing Mentor Graphics Confidential Information
  • 5. Symmetrical Multiprocessing - SMP  Single OS instance Application Thread M Thread 1 running on homogenous cores Nucleus Middleware Nucleus SMP Core N Core 1 Multicore Processor Mentor Graphics Confidential Information
  • 6. Asymmetrical Multiprocessing - AMP  Multiple OS Application 1 Application 2 Thread m Thread 1 Thread M Thread 1 instances running on heterogeneous or homogenous cores Android Middleware Linux MCAPI Nucleus Core N Core 1 Multicore Processor Mentor Graphics Confidential Information
