摘要： The present invention provides a method, apparatus and article of manufacture, for fast context saving in transactional memory. The method creates a mapping table that includes entries corresponding to architectural registers. Each entry includes a physical register index and shadow bit of a first physical register mapped to an architectural register. In response to a detection that an update occurs to an architectural register in a transaction and its shadow bit being an invalid value, the method sets the shadow bit to be a valid value and sets a shadow register for the architectural register using the physical register index of the first physical register. The method maps a second physical register to the shadow register in order to save a modified value generated by an update process and saves the original value before the update process by use of the first physical register corresponding to the architecture register.

摘要： A method and apparatus for implementing transactional memory (TM). The method includes: allocating a hardware-based transaction footprint recorder to the transaction, for recording footprints of the transaction when a transaction is begun; determining that the transaction is to be switched out; and switching out the transaction, where the footprints of the switched-out transaction are still kept in the hardware-based transaction footprint recorder. According to the present invention, transaction switching is supported by TM, and the cost of conflict detection between an active transaction and a switched-out transaction is greatly reduced since the footprints of the switched-out transaction are still kept in the hardware-based transaction footprint recorder.

摘要： The present disclosure provides a method, device, and system for processing a request in a multi-core system. The method comprises steps of: receiving a request for data by a filter from a requesting unit; comparing an indicator indicative of a logical partition in the request with an indicator indicative of the logical partition in a record of the filter; searching in a unit where the filter is located based on the request and returning a search result to the requesting unit if a comparison result matches; and returning a NONE response to the requesting unit from the filter if the comparison result does not match.
