    摘要: A method for supporting low-overhead memory locks within a multi-processor system is disclosed. A lock control section is initially assigned to a data block within a system memory of the multiprocessor system. In response to a request for accessing the data block by a processing unit within the multiprocessor system, a determination is made by a memory controller whether or not the lock control section of the data block has been set. If the lock control section of the data block has been set, the request for accessing the data block is ignored. Otherwise, if the lock control section of the data block has not been set, the lock control section of the data block is set, and the request for accessing the data block is allowed.

In response to a request for accessing the data block by a processing unit, a determination is made whether or not the lock control section of the data block has been set. If the lock control section has been set, another determination is made whether or not the requesting processing unit is located beyond a predetermined distance from a memory controller. If the requesting processing unit is located beyond a predetermined distance from the memory controller, the requesting processing unit is invited to perform other functions; otherwise, the number of the requesting processing unit is placed in a queue table. However, if the lock control section has not been set, the lock control section of the data block is set, and the access request is allowed.

    摘要: A heterogeneous processing element model is provided where I/O devices look and act like processors. In order to be treated like a processor, an I/O processing element, or other special purpose processing element, must follow some rules and have some characteristics of a processor, such as address translation, security, interrupt handling, and exception processing, for example. The heterogeneous processing element model puts special purpose processing elements on the same playing field as processors, from a programming perspective, operating system perspective, power perspective, as the processors. The operating system can get work to a security engine, for example, in the same way it does to a processor.

    摘要: A locking mechanism for supporting distributed computing within a multiprocessor system is disclosed. A lock control section and a stage control section are assigned to a data block within a system memory. In response to a request for accessing the data block by a processing unit, a determination is made by a memory controller whether or not the lock control section of the data block has been set. If the lock control section of the data block has been set, the access request is denied. Otherwise, if the lock control section of the data block has not been set, another determination is made whether or not a current processing stage of the requesting processing unit matches a processing stage indicated by the stage control section. If the current processing stage of the requesting processing unit does not match the processing stage indicated by the stage control section, the access request is denied; otherwise, the access request is allowed.

    摘要: A data processing system includes an interconnect fabric, a system memory coupled to the interconnect fabric and including a virtual barrier synchronization region allocated to storage of virtual barrier synchronization registers (VBSRs), and a plurality of processing units coupled to the interconnect fabric and operable to access the virtual barrier synchronization region of the system memory. Each of the plurality of processing units includes a processor core and a cache memory including a cache array that caches VBSR lines from the virtual barrier synchronization region of the system memory and a cache controller. The cache controller, responsive to a store request from the processor core to update a particular VBSR line, performs a non-blocking update of the cache array in each other of the plurality of processing units contemporaneously holding a copy of the particular VBSR line by transmitting a VBSR update command on the interconnect fabric.
