Abstract: PROBLEM TO BE SOLVED: To provide a method for providing an atomic update primitive into an asymmetric single-chip heterogeneous multiprocessor computer system having a shared memory with DMA transfer. SOLUTION: At least one lock line command is generated from a set including a reserved Get Lock Line command, a Put Lock Line Conditional command, and an unconditional Put Lock Line command.

Abstract: 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.

Abstract: 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.
