METHOD AND DEVICE FOR IMPLEMENTING REPLACEMENT OF THREAD FOR OPTIMAL PERFORMANCE BY TWO-TIERED MULTI-THREADING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for implementing replacement of a thread for the optimal performance by two-tiered multi-threading structure.;SOLUTION: A thread state storage in a first tier stores the restricted number of executable thread register states. A storage function in a second tier stores the second number of thread states larger than the restricted number of executable thread register state. Each of the stored thread states includes preliminarily defined selection data. Executable thread selection logic coupled between the thread state storage in the first tier and the thread storage function in the second tier uses the stored preliminarily defined selection data for selectively replacing thread states between the restricted number of executable thread register states in the first tier and the thread storage function in the second tier.;COPYRIGHT: (C)2004,JPO
