嵌入式系統多核通訊標準MCAPI

    多核是Embedded System必然發展方向，那麼多核間通訊也必然成為首先要解決的問題。目前主流ARM、DSP等均支援MCAPI。

ULTICORE COMMUNICATIONS API WORKING GROUP

Objective
Provides a standardized API for communication and synchronization between closely distributed cores and/or processors in embedded systems. 

Overview
The purpose of MCAPI, which is a message-passing API, is to capture the basic elements of communication and synchronization that are required for closely distributed (multiple cores on a chip and/or chips on a board) embedded systems. The target systems for
such an API will span multiple dimensions of heterogeneity (e.g., core heterogeneity, interconnect heterogeneity, memory heterogeneity, operating system heterogeneity, software toolchain heterogeneity, and programming language heterogeneity).

While many industry standards exist for distributed systems programming, they have primarily been focused on the needs of widely distributed systems, SMP systems, or specific application domains (for example scientific computing.) Thus, the Multicore Communications
API from the Multicore Association has similar, but more highly constrained, goals than these existing standards with respect to scalability and fault tolerance, yet has more generality with respect to application domains.
