What is a platform?
z “A platform is, in general, an abstraction that covers a number of
possible refinements into a lower level. For every platform, there is
a view that is used to map the upper layers of abstraction into the
platform and a view that is used to define the class of lower level
abstractions implied by the platform”

GSRC white paper on Platform
z “An integration platform is a reuse mix-and-match environment
designed specifically to match environment designed specifically to
target an application domain. The domain is selected based on
market objectives and is selected based on market objectives and is
focused to yield a high probability of reuse over a target period of
time.”

What is a platform?
z “A platform is a collection of assets which can be used to leverage
reuse and rapidly develop new products new products. At a
minimum, it defines the operating environment, high level product
architecture for all products developed based on this platform,
and set of development policies for extending the platform and
developing point products from the platform.”

z “An embedded system platform is anarchitectural framework for
rapid integration of embedded SoC-based designs, consisting of a
