Complexity-effective superscalar processors
TL;DR: A microarchitecture that simplifies wakeup and selection logic is proposed and discussed, which will help minimize performance degradation due to slow bypasses in future wide-issue machines.
Proceedings ArticleDOI
Evaluating stream buffers as a secondary cache replacement
TL;DR: The results show that, for the majority of the benchmarks, stream buffers can attain hit rates that are comparable to typical hit rates of secondary caches, and as the data-set size of the scientific workload increases the performance of streams typically improves relative to secondary cache performance, showing that streams are more scalable to large data- set sizes.
Quantifying the Complexity of Superscalar Processors
TL;DR: Analysis indicates that window (wakeup and select) logic and operand bypass logic are likely to be the most critical in the future of superscalar processors.

TL;DR: Simulations show that Dir.i's protocol performance is comparable to more complex directory protocols, and the significant disparity in hardware complexity and the small difference in performance argue thatDir.i>1SW+ may be a more effective use of resources.

Flexible virtual queues
TL;DR: In this paper, a port ASIC selects a VOQ for transmission and then arbitrates among the VIQs of the selected VOQ to select a VIQ from which to transmit the packet.
