Does use of a multi-core processor sway the choice of an embedded OS?

[DSeif]

A recent study by Venture Development indicates that many embedded

developers still do not yet consider multiprocessing and multi-core

architecture support a highly critical factor influencing their

selection of embedded operating systems for current projects. At what point will this become a critical factor?

Most embedded multi-core applications run the OS on a single core and use the other cores for data processing so support for multi-core is not high on the list today. As the number of cores increase and customers demand greater flexibility multi-core support will become a key requirement.
