Wide-issue ILP machines can be built using the VLIW approach as many of the hardware complexities found in superscalar processors can be transferred to the compiler. However, the scalability of VLIW architectures is still constrained by the size and number of ports of the register file required by a large number of functional units. Organizations composed by clusters of a few functional units a...

This paper presents several scheduling/coscheduling techniques employed in some recent research projects. Two types of local scheduling, proportional-sharing scheduling and predictive scheduling are introduced here. With proportional-share scheduling, the resource consumption rights of each active process are proportional to the relative shares that it is allocated. While the system implementin...
