Abstract
In addition to the normal circuitry which provides the normal computation, a microprocessor is provided with one or more additional but simplified central processing units which allows additional threads of execution to occur at a slower rate. The purpose of the secondary threads is to prefetch data from external storage to main memory or from main memory to cache in order to minimize waiting by the primary thread.
