Multithreading ArchitectureIntroduction

Multithreading Architecture: Introduction [A multithreaded architecture is one in which a single processor has the ability to follow multiple streams of execution without the aid of software context switches. If a conventional processor (Figure 1.1(a)) wants to stop executing instructions from one thread and begin executing instructions from another thread, it requires software to dump the state of the running thread into memory, select another thread, and then load the state of that thread into the processor. That would typically require many thousands of cycles, particularly if the operating system is invoked. A multithreaded architecture (Figure 1.1(b)), on the other hand, can access the state of multiple threads in, or near, the processor core. This allows the multithreaded architecture to quickly switch between threads, and potentially utilize the processor resources more efficiently and effectively.] http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png

Abstract

[A multithreaded architecture is one in which a single processor has the ability to follow multiple streams of execution without the aid of software context switches. If a conventional processor (Figure 1.1(a)) wants to stop executing instructions from one thread and begin executing instructions from another thread, it requires software to dump the state of the running thread into memory, select another thread, and then load the state of that thread into the processor. That would typically require many thousands of cycles, particularly if the operating system is invoked. A multithreaded architecture (Figure 1.1(b)), on the other hand, can access the state of multiple threads in, or near, the processor core. This allows the multithreaded architecture to quickly switch between threads, and potentially utilize the processor resources more efficiently and effectively.]
