COTS-based multicores are now the preferred choice for hosting embedded applications owing to their immense computational capabilities, small form factor and low power consumption. Many of these embedded applications have real-time requirements and real-time system designers must be able assess them for their predictability and provide guarantees (at design time) that they deliver the correct functional behavior within predefined time bounds. However, the underlying architecture of commercially available multicores is extremely complex and non-amenable to straight-forward timing analysis.
