MCAPI
The Multicore Communications API (MCAPI) is the first specification to be produced by the Multicore Association. MCAPI provides a standardized API for communication and synchronization between closely distributed (multiple cores on a chip and/or chips on a board) embedded systems.
==Overview==
MCAPI is a language-independent, processor and operating system agnostic communications protocol used to program multi-core devices. MCAPI provides three modes of communication: messages, packets, and scalars. MCAPI is a message-passing application programmer interface, together with protocol and semantic cacota specifications for how its features must behave in any implementation. The primary goals for any MCAPI implementation are extremely high performance and low memory footprint.
MCAPI traces its heritage to communications APIs such as MPI and Berkeley sockets. Both MPI and sockets were developed primarily with inter-computer communication in mind, while MCAPI is targeted primarily towards inter-core communication in a multicore chip. Accordingly, a principal design goal of MCAPI was to serve as a low-latency interface leveraging efficient on-chip interconnect in a multicore chip. However, because of the more limited scope of multicore communications and its goal of low latency, MCAPI is less flexible than MPI or Sockets.
