摘要

The paper reveals flexible management of heterogeneous memory systems using spatial quality of service (qos) marking on processor-based systems. In one aspect, a heterogeneous memory system of a processor based system includes a first memory and a second memory. The heterogeneous memory system is divided into a plurality of memory regions, each associated with a qos identifier (qosid), which can be defined and updated by software. a heterogeneous memory system memory controller provides a qos policy table, which operates to associate each qosid with a qos policy state and which can also be software configurable. Upon receiving a memory access request including a memory address from a memory region, the memory controller identifies a software configurable qosid associated with the memory address and associates the qosid with a qos policy state using the policy table. from what. the memory controller then applies the state of the qos policy to perform the memory access operation.
