A Low-Overhead Reconfigurable RISC-V Quad-Core Processor Architecture for Fault-Tolerant Applications

FPGA prototyping of a RISC processor core for embedded applications

Application-specific processors offer an attractive option in the design of embedded systems by providing high performance for a specific application domain. In this work, we describe the use of a reconfigurable processor core based on an RISC architecture as starting point for application-specific processor design. By using a common base instruction set, development cost can be reduced and des...

FPGA Implementation of Quad Processor Core Architecture for Concurrent Computing

The Embedded multiprocessor core is a design philosophy that has become a mainstream in Scientific and engineering applications. Increasing performance and gate capacity of recent FPGA devices permit complex logic systems to be implemented on a single programmable device. The Embedded multiprocessors face a new problem with thread safety [5]. It is caused by the shared memory, when thread safet...

A Fault-tolerant Architecture for Automotive Applications

Introduction One of the current trends in the automotive industry is the development of full-authority drive-by-wire (also known as X-by-Wire) systems and their future integration into vehicles [1]. These systems follow the same principles as fly-by-wire systems that are already successfully used in modern aircraft. They integrate functions like steering and braking into a distributed real-time...

Low Overhead Fault Tolerant Networking in Myrinet

Low overhead fault-tolerant FPGA systems

Fault-tolerance is an important system metric for many operating environments, from automotive to space exploration. The conventional technique for improving system reliability is through component replication, which usually comes at significant cost: increased design time, testing, power consumption, volume, and weight. We have developed a new faulttolerance approach that capitalizes on the un...
