Abstract
Atomic operation may be implemented in a processor system comprising a main memory and a power processor element (PPE) including a power processor unit (PPU) coupled to an external cache. The PPE may atomically load data from a lock-line in the main memory into a first location X in the external cache. A size of the data and the lock line may be larger than a data size for the standard atomic operations that may be performed with the PPE. The data may be reserved in a second location Y in the external cache.
