Abstract

This paper presents an integrated compiler, runtime control, and hardware solution to improve inter-thread communication and synchronization in a multithreaded processor architecture. Multithreading improves processor utilization by exploiting more parallelism. The improvement in utilization, however, is hindered by inter-thread communication and synchronization problems, which incur extra communication overhead and thus degrade the performance of the system. In this paper, we propose efficient inter-thread communication and synchronization schemes based on a superscalar DLX processor with multithreading functionality. The compiler, runtime control, and hardware support used in the schemes are discussed. Simulations are presented to show the effectiveness of the proposed schemes.
