Abstract	:	Simultaneous Multithreading (SMT) is a technique to execute multiple threads inparallel in a single processor pipeline. An SMT processor has shared instruction queuesand functional units and these resources are utilized efficiently without being wasted.Because the instruction queues and functional units are shared by multiple threads, it isvery important to decide which threads to fetch instructions from every cycle.This paper investigates 2-level fetch policies and other techniques with a view toimprove both throughput and fairness. To measure the potential of the 2-level fetchpolicies, simulations are conducted on 4 different benchmark combinations with twoSMT configurations, and simulation results are compared with those of ICOUNT andLC-BPCOUNT, two existing fetch policies. Our detailed experimental evaluationconfirms that the 2-level fetch policies outperform both ICOUNT and LC-BPCOUNT interms of throughput, as well as fairness............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
