Abstract
A method for transferring data between a processor and a memory includes (A) executing, at the processor, an instruction that includes (i) a specifier of a location in a storage resource local to the processor, (ii) a specifier of an address in the memory, and (iii) a specifier of a size of a data block, (B) providing, from the processor to a controller, a set of control signals indicating (i) the address in the memory, and (ii) the size of the data block; and (C) transferring, by the controller, in response to receipt of the set of control signals, the data block atomically between the storage resource and the memory, without the processor having to first request a lock on the memory.
