ADDRESS EXPANSION AND CONTRACTION IN A MULTITHREADING COMPUTER SYSTEM
摘要
A computer system includes a configuration with a core configurable between a single thread (ST) mode and a multithreading (MT) mode. The ST mode addresses a primary thread and the MT mode addresses the primary thread and one or more secondary threads on shared resources of the core. A multithreading facility is configured to control utilization of the configuration to perform a method that includes accessing the primary thread in the ST mode using a core address value and switching from the ST mode to the MT mode. The primary thread or one of the one or more secondary threads is accessed in the MT mode using an expanded address value, where the expanded address value includes the core address value concatenated with a thread address value.
