Abstract:
Embodiments are described for a method for controlling access to memory in a processor-based system comprising monitoring a number of interference events, such as bank contentions, bus contentions, row-buffer conflicts, and increased write-to-read turnaround time caused by a first core in the processor-based system that causes a delay in access to the memory by a second core in the processor-based system; deriving a control signal based on the number of interference events; and transmitting the control signal to one or more resources of the processor-based system to reduce the number of interference events from an original number of interference events.
