Abstract
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.
