Abstract
Provided is a hardware accelerator and method, central processing unit, and computing device. A hardware accelerating method includes, in response to a request for a new task issued by a hardware thread, accelerating processing of the new task and producing a processing result for the task. A predicting step predicts total waiting time of the new task for returning to a specified address associated with the hardware thread.
Claims8
A hardware accelerating method, comprising:
- in response to a request for a new task issued by a hardware thread, accelerating processing of the new task by a hardware accelerator and producing a processing result for the task;
- and
- predicting total waiting time of the new task for returning to a specified address associated with the hardware thread based upon a sum of time required by the hardware accelerator to complete execution of the new task itself and time required by the hardware accelerator to complete those tasks that have not been completed therein when the new task is received;
- and
- wherein the request issued by the hardware thread comprises an address of an inner register of the hardware thread to specify the specified address associated with the hardware thread to which the total waiting time of the new task will be returned.
