Abstract
Programmable data storage memory hierarchy techniques are described. In one example, a data storage system includes a memory hierarchy and a data movement controller. The memory hierarchy includes a hierarchical arrangement of a plurality of memory buffers. The data movement controller is configured to receive a data movement command and control data movement between the plurality of memory buffers based on the data movement command.
Claims20
A data storage system comprising:
- a memory hierarchy having a hierarchical arrangement of a plurality of memory buffers;
- and
- a data movement controller configured to receive a data movement command and control movement of data between the plurality of memory buffers based on the data movement command.
A device comprising:
- an execution unit implemented in hardware of an integrated circuit and configured to generate data movement commands;
- and
- a data storage system implemented in the hardware of the integrated circuit, the data storage system including a plurality of data movement controllers disposed, respectively, in a plurality of cache levels, the plurality of data movement controllers configured to control data movement between the plurality of cache levels through execution of the data movement commands.
A method comprising:
- receiving a data movement command from an execution unit at a data movement controller of a data storage system;
- and
- transmitting data between a first memory buffer specified by the data movement command and a second memory buffer specified by the data movement command by executing the data movement command by the data movement controller, the first memory buffer and the second memory buffer arranged to form a subset of a memory hierarchy.
