摘要:
Systems and methods establish communication and control between various heterogeneous processors in a computing system so that an operating system can run an application across multiple heterogeneous processors. With a single set of development tools, software developers can create applications that will flexibly run on one CPU or on combinations of central, auxiliary, and peripheral processors. In a computing system, application-only processors can be assigned a lean subordinate kernel to manage local resources. An application binary interface (ABI) shim is loaded with application binary images to direct kernel ABI calls to a local subordinate kernel or to the main OS kernel depending on which kernel manifestation is controlling requested resources.
