Abstract
A data access system includes a storage device, an instruction management device, and a host device. The host device is configured to transmit an access instruction associated with an access operation directed to an intended physical address of the storage device to the instruction management device, which compares the access instruction with a specified instruction list. When the instruction management device determines that the access instruction conforms with an instruction included in the specified instruction list, the instruction management device is configured to generate a modified access instruction associated with an access operation directed to a target physical address that is different from the intended physical address of the storage device.
Claims15
A data access system comprising:
- a storage device;
- an instruction management device that is coupled to said storage device and that includes a comparing module, an instruction processing module, and a storage medium, said instruction management device having a specified instruction list established therein;
- and
- a host device coupled to said instruction management device and configured to transmit an access instruction associated with an access operation directed to an intended physical address of said storage device to said instruction management device;
- wherein said comparing module of said instruction management device is configured to compare the access instruction received from said host device with the specified instruction list;
- and
- wherein, when said comparing module determines that the access instruction conforms with an instruction included in the specified instruction list, said instruction processing module is configured to generate a modified access instruction associated with an access operation directed to a target physical address that is different from the intended physical address of said storage device.
An instruction management device that is to be coupled between a host device and a storage device for processing an access instruction from the host device, the access instruction being associated with an access operation directed to an intended physical address of the storage device, said instruction management device having a specified instruction list established therein and comprising:
- a comparing module that is configured to compare the access instruction received from the host device with the specified instruction list;
- a storage medium;
- and
- an instruction processing module that, when said comparing module determines that the access instruction conforms with an instruction included in the specified instruction list, is configured to generate a modified access instruction associated with an access operation directed to a target physical address that is different from the intended physical address of said storage device.
