Tempranillo: Non-Speculative Early Register Release

Abstract: Limited by the breakdown of technology scaling, CPU architects are looking for creative solutions to deliver performance improvements while unable to traditionally scale up microarchitectural structures. One promising approach is engineering a microarchitecture that uses resources more efficiently, for...

MIMO Detection via Gaussian Mixture Expectation Propagation: A Bayesian Machine Learning Approach for High-Order High-Dimensional MIMO Systems

MIMO systems can simultaneously transmit multiple data streams within the same frequency band, thus exploiting the spatial dimension to enhance performance. MIMO detection poses considerable challenges due to the interference and noise introduced by the concurrent transmission of multiple streams. Efficient Uplink...

To Cross, or Not to Cross Pages for Prefetching?

Despite processor vendors reporting that cache prefetchers operating with virtual addresses are permitted to cross page boundaries, academia is focused on optimizing cache prefetching for patterns within page boundaries. This work reveals that page-cross prefetching at the first-level data cache...

AP cooperation in Wi-Fi: Joint transmission with a novel precoding scheme, resilient to phase offsets between transmitters

Multi Access-Point (M-AP) cooperation is expected to play a key role in the next-generation Wi-Fi standard (namely the upcoming IEEE WLAN 802.11bn/UHR, dubbed Wi-Fi-8), particularly in dense deployments where inter-cell interference hinders further increase in network capacity. Among the various...

Universal Virtual Lab for Fast and Accurate Performance Assessments in Nonlinear DWDM Systems with Digital Subcarrier Multiplexing

An extended Universal Virtual Lab method is presented for performance assessments of nonlinear DWDM links using 800 Gb/s digital subcarrier multiplexed channels, while accounting for NLIN correlation properties, Tx\Rx imperfections and adaptive equalization algorithms. We report accuracy errors below 0.08...

Active Learning via Predictive Normalized Maximum Likelihood Minimization

Machine learning systems require massive amounts of labeled training data in order to achieve high accuracy rates. Active learning uses feedback to label the most informative data points and significantly reduce the training set size.
