TRANSACTIONAL MEMORY THAT IS PROGRAMMABLE TO OUTPUT AN ALERT IF A PREDETERMINED MEMORY WRITE OCCURS

摘要

A transactional memory receives a command, where the command includes an address and a novel GAA (Generate Alert On Action) bit. If the GAA bit is set and if the transactional memory is enabled to generate alerts and if the command is a write into a memory of the transactional memory, then the transactional memory outputs an alert in accordance with preconfigured parameters. For example, the alert may be preconfigured to carry a value or key usable by the recipient of the alert to determine the reason for the alert. The alert may be set up to include the address of the memory location in the transactional memory that was written. The transactional memory may be set up to send the alert to a predetermined destination. The outputting of the alert may be a writing of information into a predetermined destination, or may be an outputting of an interrupt signal.

1. A transactional memory, comprising:
a memory; and an interface circuit that receives a command onto the transactional memory, wherein the command includes an incoming address and a “Generate Alert On Action” (GAA) bit, wherein if the command is a command to write into the memory and the GAA bit is set then the interface circuit outputs an alert from the transactional memory.
