Function callback mechanism between a Central Processing Unit (CPU) and an auxiliary processor

A method for function operation between a first processor and a second processor, said method comprising:

• pushing a function, by a first execution unit (EU) of one or more EUs of said first processor, to a first double-ended queue (Deque) of one or more Deques, said first Deque stored in a shared virtual memory (SVM) coupled to said first and second processors;
• popping the function from said first Deque, by a first request handler thread of one or more request handler threads executing on said second processor;
• executing, by said first request handler thread, the function;
• and
• generating, by said first request handler thread, a completion signal to said first EU in response to completion of said function.

At least one computer-readable storage medium having instructions stored thereon which when executed by a processor result in the following operations for a function between a first processor and a second processor, said operations comprising:

• pushing the function, by a first execution unit (EU) of one or more EUs of said first processor, to a first double-ended queue (Deque) of one or more Deques, said one or more Deques stored in a shared virtual memory (SVM) coupled to said first and second processors;
• popping the function from said first Deque, by a first request handler thread of one or more request handler threads executing on said second processor;
• executing, by said first request handler thread, the function;
• and
• generating, by said first request handler thread, a completion signal to said first EU in response to completion of said function.
