Abstract: Methods and apparatus monitor memory access activities of non-real-time processing engines to determine time intervals when the memory access activities are low. When such time intervals are found, the methods and apparatus perform burst memory access control for real-time processing engines by bursting data from a memory to a burst memory buffer, or from the burst memory buffer to the memory, to allow fast data access by the real-time processing engines.

Abstract: A processor monitors, directly or indirectly, the amount of time it takes for the memory controller to respond to one or more memory access requests. When this memory access latency indicates that a memory latency tolerance of a program thread has been exceeded, the processor can apportion additional power to the memory controller, thereby increasing the speed with which the memory controller can process memory access requests.

Abstract translation: 处理器直接或间接地监视内存控制器响应一个或多个存储器访问请求所花费的时间。 当该存储器访问延迟指示已经超过程序线程的存储器延迟容差时，处理器可以向存储器控制器分配额外的电力，从而提高存储器控制器可以处理存储器访问请求的速度。
