摘要： There is disclosed a method and apparatus for handling transaction buffer overflow in a multi-processor system as well as a transaction memory system in a multi-processor system. The method comprises the steps of: when overflow occurs in a transaction buffer of one processor, disabling peer processors from entering transactions, and waiting for any processor having a current transaction to complete its current transaction; re-executing the transaction resulting in the transaction buffer overflow without using the transaction buffer; and when the transaction execution is completed, enabling the peer processors for entering transactions.

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： Disclosed is a method of recognizing a process in a full-system Instruction Set Architecture (ISA) emulator, comprising the steps of: recognizing a process based on a base address of a page table thereof, recognizing the switch between the processes when said base address of the page table has changed, recognizing the termination of a recorded process when the base address of the page table of the process which tries to modify the page table is not equal to the base address of the page table of the recorded process in the page table. With the recognized process, the binary translation results indexed based on content can be saved into a corresponding process repository, thereby achieving the permanent saving of the translation results and the reuse of translation and optimization on the basis of a previously executed program. Consequently, the overall performance of the full-system Industry Standard Architecture emulator is enhanced.
