Abstract
In a multi-threaded system, such as in a multi-processor system, different types of fences are provided to force completion of programmatically earlier instructions in a program. The types of fences can be thread-specific, and different types of fences are used based on different kinds of conditions, instructions, operations, or memory types. When a fence is executed, senior stores, request buffers, bus queues, or any combination of these stages in an execution pipeline can be drained. Fetches at a front end of the pipeline can also be killed to ensure that the bus queue can be drained.
