There's an interesting editorial column 'Multicore Processing Becomes the New Mainstream' in the latest edition of COTS Journal. Jeff Child discusses how multicore processors, after becoming all pervasive in the desktop and server market, are now becoming the norm for embedded aerospace and defence systems. He also shares some insights into why the transition to multicore is necessary, and provides an example of the deployment of multicore in the Aegis Modernisation Programme (AMOD).
Rather tantalizingly, Jeff only mentions software architectures in his final paragraph (maybe that's a subject for a future editorial), where he contrasts the use of Symmetric Multiprocessing (SMP) on multicore devices with tiled processors (which can be massively parallel architectures).
