Restricted Fetch and Φ operations for parallel processing
Gurindar S. Sohi, James E. Smith, James R. Goodman · 1989
This paper discusses a restricted form of the general Fetch&P operation and how the restricted form can be combined. In this restricted form, all processors participating in the combining have identical Fetch&P operations. Most applications of Fetch&P proposed in the literature satisfy the restrictions imposed. We show how this restricted form of Fetch&P allows an easy implementation of combining, especially in bus-based multiprocessors and multiprocessors with a separate synchronization memory. Applications of the proposed restricted Fetch&P operation are also considered.
