Method and apparatus for supporting vector operations on a multi-threaded microprocessor

摘要

One embodiment of the present invention provides a system that supports vector operations on a multi-threaded microprocessor. During operation, the system detects a vector instruction in a program. The system maps this vector instruction onto the thread contexts of the multi-threaded microprocessor. As part of the mapping process, the system splits the vector instruction across a set of threads that execute in parallel and generates a set of instructions for the set of threads. This mapping process allows the vector instruction to be executed efficiently across multiple threads.
