METHOD TO PROVIDE ATOMIC UPDATE PRIMITIVE IN ASYMMETRIC HETEROGENEOUS MULTIPROCESSOR ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide for atomic update primitives in an asymmetric single-chip heterogeneous multiprocessor computer system having a shared memory with DMA transfers. SOLUTION: 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.
