Reconfigurable Field Programmable Gate Arrays (FPGAs) are growing the attention of developers of mission- and safety-critical applications (e.g., aerospace ones), as they allow unprecedented levels of performance, which are making these devices particularly attractive as ASICs replacement, and as they offer the unique feature of in-the-field reconfiguration. However, the sensitivity of reconfigurable...
This paper proposes Flex Core, a hybrid processor architecture where an on-chip reconfigurable fabric (FPGA) is tightly coupled with the main processing core. Flex Core provides an efficient platform that can support a broad range of run-time monitoring and bookkeeping techniques. Unlike using custom hardware, which is more efficient but often extremely difficult and expensive to incorporate into...
New media and signal processing applications demand ever higher performance while operating within the tight power constraints of mobile devices. A range of hardware implementations is available to deliver computation with varying degrees of area and power efficiency, from general-purpose processors to application-specific integrated circuits (ASICs). The tradeoff of moving towards more efficient...
The procedure of design and verification for a 16-bit RISC processor is introduced in this paper. The proposed processor has Harvard architecture and consists of 24-bit address, 5-stage pipeline instruction execution, and internal debug logic. ADPCM vocoder and SOLA algorithm are successfully carried out on the processor made with FPGA.
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...
