Flexible register management using reference counting
Found in: High-Performance Computer Architecture, International Symposium on
By Steven Battle,Andrew D. Hilton,Mark Hempstead,Amir Roth
Issue Date:February 2012
pp. 1-12
Conventional out-of-order processors that use a unified physical register file allocate and reclaim registers explicitly using a free list that operates as a circular queue. We describe and evaluate a more flexible register management scheme -- reference c...
 
The Accelerator Store framework for high-performance, low-power accelerator-based systems
Found in: IEEE Computer Architecture Letters
By Michael J. Lyons, Mark Hempstead, Gu-Yeon Wei, David Brooks
Issue Date:July 2010
pp. 53-56
Hardware acceleration can increase performance and reduce energy consumption. To maximize these benefits, accelerator- based systems that emphasize computation on accelerators (rather than on general purpose cores) should be used. We introduce the &#82...
 
An Ultra Low Power System Architecture for Sensor Network Applications

Recent years have seen a burgeoning interest in embedded wireless sensor networks with applications ranging from habitat monitoring to medical applications. Wireless sensor networks have several important attributes that require special attention to device...
 
TinyBench: The Case For A Standardized Benchmark Suite for TinyOS Based Wireless Sensor Network Devices
Found in: Local Computer Networks, Annual IEEE Conference on
By Mark Hempstead, Matt Welsh, David Brooks
Issue Date:November 2004
pp. 585-586
The growing wireless sensor network research community lacks a standard method for evaluating hardware platforms. Traditional benchmark suites do not sufficiently address the needs of sensor network designers. This work provides motivation for a benchmark ...
   
Platform-independent analysis of function-level communication in workloads
Found in: 2013 IEEE International Symposium on Workload Characterization (IISWC)
By Siddharth Nilakantan,Mark Hempstead
Issue Date:September 2013
pp. 196-206
The emergence of many-core and heterogeneous multicore processors has meant that data communication patterns increasingly determine application performance. Microprocessor designers need tools that can extract and represent these producer-consumer relation...
   
The accelerator store: A shared memory framework for accelerator-based systems
Found in: ACM Transactions on Architecture and Code Optimization (TACO)
By David Brooks, Mark Hempstead, Gu-Yeon Wei, Michael J. Lyons
Issue Date:January 2012
pp. 1-22
This paper presents the many-accelerator architecture, a design approach combining the scalability of homogeneous multi-core architectures and system-on-chip's high performance and power-efficient hardware accelerators. In preparation for systems containin...
