Abstract: Systems, methods, and apparatuses for resource bandwidth monitoring and control are described. For example, in some embodiments, an apparatus comprising a requestor device to send a credit based request, a receiver device to receive and consume the credit based request, and a delay element in a return path between the requestor and receiver devices, the delay element to delay a credit based response from the receiver to the requestor are detailed.

Abstract: Embodiments for allocating shared resources are disclosed. In an embodiment, an apparatus includes a core and a hardware rate selector. The hardware rate selector is to, in response to a first indication that demand for memory bandwidth from the core has reached a threshold value, determine a delay value to be used to limit allocation of memory bandwidth to the core. The hardware rate selector includes a controller having a first counter to count a second indication of demand for memory bandwidth from the first core and a second counter to count expirations of time windows. The first indication is based on a difference between the first counter value and the second counter value.
