- Microarchitecture-Based Introspection: A Technique for Transient-Fault Tolerance in Microprocessors
- This paper proposes Microarchitecture-Based Introspection MBI, a transient-fault detection technique, which utilizes the wasted processing bandwidth during long-latency cache misses for redundant execution of the instruction stream. MBI has modest hardware cost, requires minimal modifications to the existing microarchitecture, and is particularly well suited for memory-intensive applications. The evaluation reveals...

- A Space-Time Block-Coded OFDM Scheme for Unknown Frequency-Selective Fading Channels
- This paper introduces a space-time block-coded orthogonal frequency-division multiplexing (STBC-OFDM) scheme for frequency-selective fading channels, which does not require channel knowledge either at the transmitter or at the receiver. The decoding algorithm is based on generalized maximum-likelihood sequence estimation. Due to the assumed orthogonality structure of STBC, the decoding rule...

- Implementation of Real-Time Virtual CPU Partition on Linux
- A real-time virtual resource is an abstraction for resource sharing where the application task groups sharing a resource must meet timing constraints in the absence of knowledge of all the timing requirements of all the task groups, thus prohibiting a global schedulability analysis. RTVR addresses the issues of application isolation...

- Cache Filtering Techniques to Reduce the Negative Impact of Useless Speculative Memory References on Processor Performance
- High-performance processors employ aggressive speculation and prefetching techniques to increase performance. Speculative memory references caused by these techniques sometimes bring data into the caches that are not needed by correct execution. This paper proposes the use of the first-level caches as filters that predict the usefulness of speculative memory references....

- Address-Value Delta (AVD) Prediction: Increasing the Effectiveness of Runahead Execution by Exploiting Regular Memory Allocation Patterns
- While runahead execution is effective at parallelizing independent long-latency cache misses, it is unable to parallelize dependent long-latency cache misses. To overcome this limitation, this paper proposes a novel technique, Address-Value Delta AVD prediction. An AVD predictor keeps track of the address pointer load instructions for which the arithmetic difference...

- Understanding the Effects of Wrong-Path Memory References on Processor Performance
- High-performance out-of-order processors spend a significant portion of their execution time on the incorrect program path even though they employ aggressive branch pre-diction algorithms. Although memory references generated on the wrong path do not change the architectural state of the processor, they can affect the arrangement of data in the...

- Real-Time End-to-End Network Monitoring in Large Distributed Systems
- Measuring real-time end-to-end network path performance metrics is important for several distributed applications such as media streaming systems (e.g., for switching to paths with higher bandwidth and lower jitter) and content distribution systems (e.g., for selecting servers with lower latency). However, it is challenging to perform such end-to-end pairwise measurements...

- Multiuser Limited Feedback for Wireless Multi-Antenna Communication
- For a wireless multi-antenna network with a large number of users, the sum capacity scales at most linearly with the number of antennas and double logarithmically the number of users. Achieving this optimal capacity scaling potentially requires feedback of Channel State Information CSI from all users, leading to overflow of...
