Abstract
A storage device includes a memory device including a first memory region configured to store autonomous driving analysis data and a controller configured to control a memory operation of the memory device, wherein the controller includes a management circuit configured to monitor a plurality of pieces of target information related to autonomous driving, predict a shortage of the first memory region, and perform an operation to increase a free space of the first memory region based on a result of the prediction.
Claims18
A storage device, comprising:
- a memory device including a first memory region configured to store autonomous driving analysis data;
- a policy register configured to be set to a first policy by a host as a set policy for managing the autonomous driving analysis data;
- and
- a controller configured to control a memory operation of the memory device,
- wherein the controller includes a management circuit configured to:
- monitor a plurality of pieces of target information related to autonomous driving,
- predict a shortage of the first memory region, and
- perform an operation to increase a free space of the storage device based on a result of the prediction,
- wherein the operation to increase the free space comprises transmitting, by the management circuit, a policy change request to the host, the policy change request requesting to change the first policy into a second policy,
- wherein the policy register stores a first parameter indicating a storage duration of the autonomous driving analysis data, and a second parameter indicating a unit in which the autonomous driving analysis data is deleted, and
- wherein the policy change request is configured to cause modification of at least one of the first parameter or the second parameter to increase the free space.
An operating method of a storage device of an autonomous vehicle, wherein the storage device is communicatively connected to a host device including a plurality of zonal control units (ZCUs), the operating method comprising:
- storing first autonomous driving analysis data received from the host device in a first memory region of the storage device;
- monitoring a plurality of pieces of target information related to autonomous driving and predicting a shortage of the first memory region;
- and
- performing an operation to increase a free space of the storage device, wherein the performing of the operation for increasing the free space of the storage device includes setting a part of a second memory region of the storage device, the second memory region storing general data, to operate as a memory region storing second autonomous driving analysis data to be received from the host device.
A storage device comprising:
- a memory device including a first memory region and a second memory region, the first memory region configured to store autonomous driving analysis data received from a host, the second memory region configured to store general data;
- and
- a controller configured to manage first autonomous driving analysis data stored in the first memory region, based on a policy initially set by the host,
- wherein the controller is further configured to
- monitor second autonomous driving analysis data received from the host,
- predict a shortage of the first memory region, and
- selectively perform one of
- an operation of, based on a result of the prediction, requesting the host to change at least one of a storage duration of the autonomous driving analysis data or a unit in which the autonomous driving analysis data is deleted, or
- an operation of setting a part of the second memory region to operate as a memory region storing third autonomous driving analysis data to be received from the host.
