Asynchronous circuits possibly have several potential advantages in comparison with synchronous one. In this paper, we attempt to introduce asynchronous circuit design method into the control unit of our 8-bit microprocessor by the burst-mode design method and implemented the asynchronous 8-bit microprocessor with outputs to observe all registers and the program counter by using a standard FPGA development...
The purpose of TAFT fault tolerance studies conducted at CNES is to prepare the space community for the significant evolution linked to the usage of COTS components for developing spacecraft supercomputers. CNES has patented the DMT and DT2 fault-tolerant architectures with 'light' features. The development of a DMT/DT2 testbench based on a PowerPC7448 microprocessor from e2v is presented in this...
Designing dependable systems is a systematic task where area, power and performance are competing constraints. In many applications, design restrictions do not permit the total hardening of a design, leaving some internal circuitry vulnerable to radiation effects. Hierarchical analysis is necessary to identify the relative importance and vulnerability of individual sub-circuits in a design so that...
