Abstract
A cache and a method for performing data copying are provided. The cache includes a copy logic and be connected to a processor through a first bus and to a memory controller through a second bus, which is different from the first bus. Moreover, the copy logic may perform data copying through the second bus based on a data copy command received from the processor.
Claims20
A cache for performing data copying, the cache comprising:
- a copy logic,
- wherein the cache is connected to a processor through a first bus and to a memory controller through a second bus, which is different from the first bus, and
- wherein the copy logic performs data copying through the second bus based on a data copy command received from the processor.
A method of performing data copying, the method comprising:
- receiving, at a cache, a data copy command from a processor through a first bus;
- and
- performing, at the cache, data copying based on the received data copy command through a second bus, which is different from the first bus.
A computing device for performing data copying, the computing device comprising:
- a processor;
- a cache connected to the processor by a system bus;
- a memory controller connected to the cache by a local bus;
- and
- a memory connected to the memory controller,
- wherein the cache performs data copying on the memory by using the local bus based on a data copy command received from the processor.
