wrBench: Comparing Cache Architectures and Coherency Protocols on ARMv8 Many-Core Systems [PDF]
, 2023 Cache performance is a critical design constraint for modern many-core systems. Since the cache often works in a “black-box” manner, it is difficult for the software to reason about the cache behavior to match the running software to the underlying ...

Binary Field Multiplication on ARMv8 [PDF]
, 2015 In this paper, we show efficient implementations of binary field multiplication over ARMv8. We exploit an advanced 64-bit polynomial multiplication (\texttt{PMULL}) supported by ARMv8 and conduct multiple levels of asymptotically faster Karatsuba ...

Concurrency and Computation: Practice and Experience, Volume 35, Issue 25, 15 November 2023., 2023 Summary Asymmetric multicore processors (AMPs) couple high‐performance big cores and power‐efficient small ones, all exposing a shared instruction set architecture to software, but with different microarchitectural features. The energy efficiency benefits of AMPs, together with the general‐purpose nature of the various cores, have led hardware ...

RootBot: High‐throughput root stress phenotyping robot
Applications in Plant Sciences, Volume 11, Issue 6, November-December 2023., 2023 Abstract Premise Higher temperatures across the globe are causing an increase in the frequency and severity of droughts. In agricultural crops, this results in reduced yields, financial losses, and increased food costs at the supermarket. Root growth maintenance in drying soils plays a major role in a plant's ability to survive and perform under ...

Characterization of data compression across CPU platforms and accelerators
Concurrency and Computation: Practice and Experience, Volume 35, Issue 20, 10 September 2023., 2023 Abstract The ever increasing amount of generated data makes it more and more beneficial to utilize compression to trade computations for data movement and reduced storage requirements. Lately, dedicated accelerators have been introduced to offload compression tasks from the main processor.

A resource efficient pseudo random number generator based on sawtooth maps for Internet of Things
SECURITY AND PRIVACY, Volume 6, Issue 5, September/October 2023., 2023 Abstract The strength of cryptographic keys rely on the random number generators (RNGs) to produce random seed values. Unfortunately there are not many RNGs options suitable for Internet of Things (IoTs) scenario, due to limited processing resources and bulk quantity of IoT data that needs to be secured.
