Multithreading Decoupled Architectures for Complexity-Effective General Purpose Computing

Decoupled architectures have not traditionally been used in the context of general purpose computing because of their inability to tolerate control-intensive code that exists across a wide range of applications. This work investigates the possibility of using multithreading to overcome the loss of decoupling dependencies that represent the cause of this main limitation in decoupled architectures. A proposal for a multithreaded decoupled control/access/execute architecture is presented as a platform for achieving high performance on general purpose workloads. It is argued that such a decoupled architecture is more complexity-effective and scalable than comparable superscalar processors, which incorporate enormous amounts of complexity for modest performance gains
