The development of FPGA-based digital signal processing devices has been gaining attention. Researchers seek to reduce power consumption and enhance signal processing quality in these devices with given resources and spatial limits. Hence, there is a need to investigate both the capability and the power consumption associated with the various digital filtering schemes commonly used in FPGA-base...
This paper presents the FPGA implementation of sliding mode control algorithm for bilateral teleoperation, such that, the problem of haptic teleoperation is addressed. The presented study improves haptic fidelity by widening the control bandwidth. For wide control bandwidth, short control periods as well as short sampling periods are required that was achieved by the FPGA. The presented FPGA de...
We describe the capabilities of and algorithms used in a new FPGA CAD tool, Versatile Place and Route (VPR). In terms of minimizing routing area, VPR outperforms all published FPGA place and route tools to which we can compare. Although the algorithms used are based on previously known approaches, we present several enhancements that improve run-time and quality. We present placement and routin...
This paper describes a structured technique for providing full observability and controllability for functionally debugging FPGA designs in hardware, capabilities which are currently not available otherwise. Similar in concept to flip-flop scan chains for VLSI, our design-level scan technique includes all FPGA flip-flops and RAMs in a serial scan chain using FPGA logic rather than transistor lo...
This paper outlines an FPGA VLSI design methodology that was used to realize a fully functioning FPGA chip in 130nm CMOS with improved routability and memory robustness. The architectural design space exploration and synthesis capability were enabled by the Verilog-to-Routing CAD tool. The capabilities of this tool were extended to enable bitstream generation and deployment. To validate the arc...
This paper presents preliminary results regarding system-level power awareness for FPGA implementations in wireless sensor networks. Re-configurability of field programmable gate arrays (FPGA) allows for significant flexibility in its applications to embedded systems. However, high power consumption in FPGA becomes a significant factor in design considerations. We present several ideas and thei...
Pseudorandom number generation (PRNG) is a key element in hardware security platforms like fieldprogrammable gate array FPGA circuits. In this article, 18 PRNGs belonging in 4 families (xorshift, LFSR, TGFSR, and LCG) are physically implemented in a FPGA and compared in terms of area, throughput, and statistical tests. Two flows of conception are used for Register Transfer Level (RTL) and High-...

For many years, research on FPGA-type programmable hardware architectures has focused mainly on optimising regular non-hierarchical architectures. In the exploration of their design space, some design parameters have a significant impact on the layout area, which is directly related to interconnect delay. An estimation of this impact can be derived from a prediction of the area of the basic FPG...
This paper proposes a new high-level approach for optimising field programmable gate array (FPGA) designs. FPGA designs are commonly implemented in low-level hardware description languages (HDLs), which lack the abstractions necessary for identifying opportunities for significant performance improvements. Using a computer vision case study, we show that modelling computation with dataflow abstr...
