A growing body of work has compiled a strong case for the single-ISA heterogeneous multi-core paradigm. A single-ISA heterogeneous multi-core provides multiple, differently-design...

The poor scalability of existing superscalar processors has been of great concern to the computer engineering community. In particular, the critical-path lengths of many components...

In this paper we present a method of describing microprocessors at different levels of temporal and data abstraction. We consider microprogrammed, pipelined and superscalar proces...
The performance of superscalar processors is more sensitive to the memory system delay than their single-issue predecessors. This paper examines alternative data access microarchi...

Out-of-order execution significantly increases the performance of superscalar processors. The out-of-order execution mechanism is, however, energy-inefficient, which inhibits scal...

An important design decision in the implementation of a superscalar processor is the amount of hardware to allocate to the instruction scheduling mechanism. Dynamic scheduling pro...
The advent of superscalar processors with out-of-order execution makes it increasingly difficult to determine how well an application is utilizing the processor and how to adapt t...

The issue logic of dynamically scheduled superscalar processors is one of their most complex and power-consuming parts. In this paper we present alternative issue-logic designs th...
As superscalar processors become increasingly wide, it is inevitable that the large set of instructions to be fetched every cycle will span multiple noncontiguous basic blocks. Th...
Conventional load/store queues (LSQs) are an impediment to both power-efficient execution in superscalar processors and scaling to large-window designs. In this paper, we propose...
