Method to Provide Atomic Update Primitives in an Asymmetric Heterogeneous Multiprocessor Environment

摘要

The present invention provides for atomic update primitives in an asymmetric single-chip heterogeneous multiprocessor computer system having a shared memory with DMA transfers. At least one lock line command is generated from a set comprising a get lock line command with reservation, a put lock line conditional command, and a put lock line unconditional command.
