SoK: Shining Light on Shadow Stacks

Control-Flow Hijacking attacks are the dominant attack vector against C/C++ programs. Control-Flow Integrity (CFI) solutions mitigate these attacks on the forward edge, i.e., indirect calls through function pointers and virtual calls. Protecting the backwa ...

Linebacker: Preserving Victim Cache Lines in Idle Register Files of GPUs

Yunho Oh

Modern GPUs suffer from cache contention due to the limited cache size that is shared across tens of concurrently running warps. To increase the per-warp cache size prior techniques proposed warp throttling which limits the number of active warps. Warp thr ...

QUASII: QUery-Aware Spatial Incremental Index

Anastasia Ailamaki, Darius Sidlauskas, Thomas Heinis, Mirjana Pavlovic

With large-scale simulations of increasingly detailed models and improvement of data acquisition technologies, massive amounts of data are easily and quickly created and collected. Traditional systems require indexes to be built before analytic queries can ...

Sub-Logarithmic Test-and-Set Against a Weak Adversary

Dan Alistarh

A randomized implementation is given of a test-and-set register with O(log log it) individual step complexity and O(n) total step complexity against an oblivious adversary. The implementation is linearizable and multi-shot, and shows an exponential complex ...

Methodology for the Digital Calibration of Analog Circuits and Systems Using Sub-binary Radix DACs

Maher Kayal, Marc Pastre

This paper presents a methodology for digitally calibrating analog circuits and systems. Based on the detection of an imperfection by a simple comparator, a successive approximations algorithm tunes a compensation current. The latter is generated by a sub- ...

A microprocessor having at least one application specific functional unit and method to design same

Paolo Ienne

Customisable embedded processors that are available on the market make it possible for designers to speed up execution of applications by using Application-specific Functional Units (AFUs), implementing Instruction-Set Extensions (ISEs). Furthermore, techn ...

Fast, quasi-optimal, and pipelined instruction-set extensions

Paolo Ienne, Philip Brisk, Ajay Kumar Verma

Nowadays many customised embedded processors offer the possibility of speeding up an application by implementing it using Application-Specific Functional units (AFUs). However, the AFUs must satisfy certain constraints in terms of read and write ports betw ...

Register File Reliability Analysis Through Cycle-Accurate Thermal Emulation

David Atienza Alonso, Pablo Garcia del Valle, José Luis Ayala Rodrigo

Continuous transistor scaling due to improvements in CMOS devices and manufacturing technologies is increasing processor power densities and temperatures; thus, creating challenges when trying to maintain manufacturing yield rates and devices which will be ...
