Runtime Reconfiguration (RTR) has been traditionally utilized as a means for exploiting the flexibility of High-Performance Reconfigurable Computers (HPRCs). However, the RTR feature comes with the cost of high configuration overhead which might negatively impact the overall performance. Currently, modern FPGAs have more advanced mechanisms for reducing the(More)
The complexity exhibited by pervasive systems is constantly increasing. Customer electronics devices provide day to day a larger amount of functionalities. A common approach for guaranteeing high performance is to include specialized coprocessor units. However, these systems lack flexibility, since one must define, in advance, the coprocessor functionality.(More)
High-Performance Reconfigurable Computing (HPRC) systems have always been characterized by their high performance and flexibility. Flexibility has been traditionally exploited through the Run-Time Reconfiguration (RTR) provided by most of the available platforms. However, the RTR feature comes with the cost of high configuration overhead which might(More)
—Performance and versatility requirements arising from escalating fabrication costs and design complexities are making reconfigurable computing technologies increasingly advantageous on the roadmap towards many-core technologies. This reformation in device architectures is necessitating a critical reformation in application design methods to bridge the(More)
The performance of security applications can be greatly improved by accelerating the cryptographic algorithms in hardware. In this paper, an implementation of the Secure Shell (SSH) application is presented. A self-reconfigurable platform based on a Xilinx Spartan-3 FPGA has been employed to implement a MicroBlaze-based embedded system, which executes SSH(More)
Numerical non-robustness is a recurring phenomenon in scientific computing. It is primarily caused by numerical errors arising because of fixed-precision arithmetic in integer and/or floating-point computations. Exact computation, based on arbitrary-precision arithmetic, has been developed over the last decade as an emerging numerical computation paradigm(More)
