Abstract
There is provided a method and a controller for performing dynamic Host Memory Buffer (HMB) management in Peripheral Component Interconnect express (PCIe) based devices. The controller estimates a potential memory requirement for one or more memory intensive operations to be performed by the PCIe based device, transmits a first request to a host device associated with the PCIe based device, the first request indicating the potential memory requirement from Host Memory Buffer (HMB) of the host device, receives a plurality of memory allocation slots from the host device based on the first request, transmits a second request comprising HMB information related to current memory requirement based on the plurality of memory allocation slots to the host device and initializes memory of the HMB allocated to the controller based on the second request, for performing the at least one of the one or more memory intensive operations.
