A multithreaded processor capable of implicit multithreaded execution of a single-thread program

摘要

A device is presented including a first processor and a second processor. A number of memory devices are connected to the first processor and the second processor. A register buffer is connected to the first processor and the second processor. A trace buffer is connected to the first processor and the second processor. A number of memory instruction buffers are connected to the first processor and the second processor. The first processor and the second processor perform single threaded applications using multithreading resources. A method is also presented where a first thread is executed from a first processor. The first thread is also executed from a second processor as directed by the first processor. The second processor executes instructions ahead of the first processor.
