Abstract:
A graphics processing unit includes a first processing controller controlling a first set of multi-threaded processors. A second processing controller controls a second set of multi-threaded processors. A serial bus connects the first processing controller to the second processing controller. The first processing controller gathers first state information from the first set of multi-threaded processors in response to a context switch token and then passes the context switch token over the serial bus to the second processing controller. The second processing controller gathers second state information from the second set of multi-threaded processors in response to the context switch token.
