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.
