Abstract:
In one embodiment, a processor comprises execution circuitry and a translation lookaside buffer (TLB) coupled to the execution circuitry. The execution circuitry is configured to execute a store instruction having a data operand; and the execution circuitry is configured to generate a virtual address as part of executing the store instruction. The TLB is coupled to receive the virtual address and configured to translate the virtual address to a first physical address. Additionally, the TLB is coupled to receive the data operand and to translate the data operand to a second physical address. A hardware accelerator is also contemplated in various embodiments, as is a processor coupled to the hardware accelerator, a method, and a computer readable medium storing instruction which, when executed, implement a portion of the method.
