Multicore Means Communication

By Mark Hermeling

Found this blog post today, which is related to my post from yesterday.
Communication in multicore is crucial. In a single core world you can
communicate through function calling and synchronize with semaphores
and mutexes. This will not work efficiently (or reliably) in a
multicore world, the best way to share data is through asynchronous
messages.

Jimmy Ray points to the multicore association and more specifically to it’s MCAPI.
A publicly available reference example of MCAPI is available, complete
with examples for you to experiment with. MACPI is a standardized
communication and synchronization interface between cores and
processors in embedded systems. Note ‘cores and processors’, it is
independent of the OS/middleware.
