Optimal bypass monitor for high performance last-level caches

• Lingda Li, Dong Tong, Zichao Xie, Junlin Lu, Xu Cheng
• 2012 21st International Conference on Parallel…
• 2012

In the last-level cache, large amounts of blocks have reuse distances greater than the available cache capacity. Cache performance and efficiency can be improved if some subset of these distant reuse… (More)

An energy-efficient branch prediction technique via global-history noise reduction

• Zichao Xie, Dong Tong, Xu Cheng
• International Symposium on Low Power Electronics…
• 2013

Accurate branch prediction can improve processor performance, while reducing energy waste. Though some existing branch predictors have been proved effective, they usually require large amount of… (More)

TAP prediction: Reusing conditional branch predictor for indirect branches with Target Address Pointers

• Zichao Xie, Dong Tong, Mingkai Huang, Xiaoyin Wang, Qinqing Shi, Xu Cheng
• 2011 IEEE 29th International Conference on…
• 2011

Indirect-branch prediction is becoming more important for modern processors as more programs are written in object-oriented languages. Previous hardware-based indirect-branch predictors generally… (More)

An adaptive filtering mechanism for energy efficient data prefetching

• Xianglei Dang, Xiaoyin Wang, Dong Tong, Zichao Xie, Lingda Li, Keyi Wang
• 2013 18th Asia and South Pacific Design…
• 2013

As data prefetching is used in embedded processors, it is crucial to reduce the wasted energy for improving the energy efficiency. In this paper, we propose an adaptive prefetch filtering (APF)… (More)

SWIP Prediction: Complexity-Effective Indirect-Branch Prediction Using Pointers

• Zichao Xie, Dong Tong, Mingkai Huang, Qinqing Shi, Xu Cheng
• Journal of Computer Science and Technology
• 2012

Predicting indirect-branch targets has become a performance bottleneck for many applications. Previous high-performance indirect-branch predictors usually require significant hardware storage or… (More)

WHOLE: A low energy I-Cache with separate way history

• Zichao Xie, Dong Tong, Xu Cheng
• 2009 IEEE International Conference on Computer…
• 2009

Set-associative instruction caches achieve low miss rates at the expense of significant energy dissipation. Previous energy-efficient approaches usually suffer from performance degradation and… (More)

VFCC: A verification framework of cache coherence using parallel simulation

• Qiaoli Xiong, Jiangfang Yi, Tianbao Song, Zichao Xie, Dong Tong
• 2013 18th Asia and South Pacific Design…
• 2013

A cache coherence protocol is a vital component of a multiprocessor to maintain the data consistency. In this paper, we proposed VFCC, which is a simulation framework to validate a cache-coherence… (More)

Improving inclusive cache performance with two-level eviction priority

• Lingda Li, Dong Tong, Zichao Xie, Junlin Lu, Xu Cheng
• 2012 IEEE 30th International Conference on…
• 2012

Inclusive cache hierarchies are widely adopted in modern processors, since they can simplify the implementation of cache coherence. However, it sacrifices some performance to guarantee inclusion.… (More)
