摘要： An atomic compare and swap operation that can be implemented in processor system having a power processor element (PPE) and a synergistic processor element (SPE) that have different sized memory transfer capabilities. The PPE notifies an SPE to perform a compare and swap operation on an address in main memory. The address has a size less than or equal to a maximum memory transfer size for the SPE and greater than a maximum memory transfer size for the PPE. The SPE atomically performs the compare and swap operation and notifies the PPE of the success or failure of the compare and swap operation.

摘要： Atomic operations may be implemented on a processor system having a main memory and two or more processors including a power processor element (PPE) and a synergistic processor element (SPE) that operate on different sized register lines. A main memory address containing a primitive is divided into a parity byte and two or more portions, wherein the parity byte includes at least one bit. A value of the parity byte determines which of the two or more portions is a valid portion and which of them is an invalid portion. The primitive is of a memory size that is larger than a maximum size for atomic operation with the PPE and less than or equal to a maximum size for atomic operation with the SPE. Read with reservation and conditional write instructions are used by both the PPE and SPE to access or update a value of the atomic.

摘要： Systems and methods for mediation of content-related services are provided. A client device playing content may send a request for a service related to the content. Configuration information is generated for the client device, reflecting a set of permissions that are determined based on a market segment of the client device. Once the client device is configured according to the set of permissions, the client device can communicate with a service provider of the requested service. Such communication and any further activity regarding the service is governed by the set of permissions, as is reporting regarding such communication and activity
