'Software Design for Multicore Systems - 2013 Edition'

摘要

At first glance, the design of software for multi-core systems appears to be similar to the design of traditional embedded multitasking software. But application software for multi-core systems can often be much larger in scale and much more complex than software that has in the past been developed for traditional single-CPU embedded systems. Hence we need some additional methodological recommendations to guide our work at this new scale and new level of complexity. In a first approximation, those guidelines can be similar to those for the design of distributed multi-processor systems. However, multi-core systems are not simply miniaturized distributed systems. Before embarking on the design of software for a multi-core system, some differences between multi-core and distributed systems must be understood, and then taken into account when architecting software that is destined to run on multi-core SOCs (Systems-On-a-Chip). Many of the design assumptions that have been the firm foundation of embedded systems multitasking software design for the past 20-30 years, are no longer valid when designing software for multi-core SOCs.
