An apparatus and method are described for coupling a front end core to an accelerator component (e.g., such as a graphics accelerator). For example, an apparatus is described comprising: an accelerator comprising one or more execution units (EUs) to execute a specified set of instructions; and a front end core comprising a translation lookaside buffer (TLB) communicatively coupled to the accelerator and providing memory access services to the accelerator, the memory access services including performing TLB lookup operations to map virtual to physical addresses on behalf of the accelerator and in response to the accelerator requiring access to a system memory.

Apparatus and method for accelerating operations in a processor which uses shared virtual memory

In one embodiment, a processor includes an accelerator, a decoder to decode a first instruction into a decoded first instruction, and a second instruction into a decoded second instruction, and an execution unit to execute the first decoded instruction to, for a thread executing on the accelerator that is to be placed in an inactive state, cause a save of context information for the thread, and a save of a vector identifying the accelerator corresponding to the context information, and execute the second decoded instruction to read the vector to determine the accelerator to restore saved context information into for the thread, read the saved context information, and restore the saved context information into the accelerator.
