Space Cyber-Physical Systems such as spacecraft and satellites strongly rely on the reliability of onboard computers to guarantee the success of their missions. Relying solely on radiation-hardened technologies is extremely expensive, and developing ...

The rapid growth of Internet of Things (IoTs) applications in various sectors has led to a significant increase in the number of IoT devices. This has led to the deployment of numerous IoT protocols to provide greater connectivity. However, this extensive ...

The RISC-V Vector Cryptography Extensions (Zvk) were ratified in 2023 and integrated into the main ISA manuals in 2024. These extensions support high-speed symmetric cryptography (AES, SHA2, SM3, SM4) operating on the vector register file and offer ...

Chisel is an open-source high-level hardware construction language embedded in Scala to facilitate parameterizable, reusable circuit design generators. It is becoming increasingly popular and has been used to design many RISC-V processor variants. ...

To improve the energy efficiency of computation, accelerators trade off performance and energy consumption for flexibility. Fixed-function accelerators reach high energy efficiency, but are inflexible. Adding programmability via an instruction set ...

Human Activity Recognition (HAR) is an important area of research due to its applications in health monitoring, elderly care, and personal fitness tracking. The challenge is deploying efficient and accurate HAR systems on resource-constrained and/...

The rapid development of ISAs has brought the issue of software compatibility to the forefront in the embedded field. To address this challenge, one of the promising solutions is the adoption of a multiple-ISA processor that supports multiple ...

Recently, a new Side-Channel Analysis (SCA)-based attack, namely the Optical Probing (OP) attack, has been shown to bypass the implemented protection mechanisms on the chip, allowing unauthorized access to confidential information such as stored ...

Fuzz testing serves as a key technique in software security aimed at identifying unexpected program behaviors by repeatedly executing the target program with auto-generated random inputs. Testing is integral to IoT device security but is hampered ...

The instruction set architecture (ISA) of vector processors operates on vectors stored in the vector register file (VRF) which needs to handle several concurrent accesses by functional units (FUs) with multiple ports. When the vector processor is running ...

Over two decades have passed since the first publication of Modern Compiler Implementation by Andrew Appel, with its second edition revised by Jens Palsberg. This textbook remains an essential guide for students, hobbyists, and researchers navigating the ...

Advances in quantum computing have posed a future threat to today’s cryptography. With the advent of these quantum computers, security could be compromised. Therefore, the National Institute of Standards and Technology (NIST) has issued a request for ...

The focus of this manuscript is related to the main safety issues regarding a mixed criticality system running multiple concurrent tasks. Our concerns are related to the guarantee of Freedom of Interference between concurrent partitions, and to ...

FPGAs have been shown to operate reliably within harsh radiation environments by employing single-event upset (SEU) mitigation techniques, such as configuration scrubbing, triple-modular redundancy, error correction coding, and radiation aware ...
