Abstract
A storage device may dynamically adjust priorities for types of data placed on a bus between the storage device and a host to optimize a bus pipeline and maximize the performance on the storage device, while minimizing inefficiencies and latencies on the storage device. A controller on the storage device may access data on a host memory buffer (HMB) and identify different types of data on a bus between the storage device and a host. The controller assigns priorities to the types of data placed on the bus and processes the data on the bus according to an assigned priority. The controller also determines a current system state and adjusts the priorities assigned to the types of data based on the current system state.
