Run-time reconfigurable FPGAs are powerful platforms for realising software-defined radio systems. This paper introduces a parametric approach to designing such systems based on application and device parameters. We analyse the potential for reconfiguration in several software-defined radio components and demonstrate how the degree of parallelism in a reconfigurable module influences reconfigur...

We present a runtime environment that partially reconfigures and executes hardware tasks on Xilinx Virtex. To that end, the FPGA’s reconfigurable surface is split into a varying number of variable-sized vertical task slots that can accommodate the hardware tasks. A bus-based communication infrastructure allows for task communication and I/O. We discuss the design of the runtime system and its p...

Reconfigurable Computing has grown to become an important and large field of research. This paper describes the implementation of a reconfigurable ALU that combines 32-bit single precision floatingpoint adder and integer ALU (arithmetic logic unit) into a single unit on FPGA. Reconfigurable ALU can perform both integer operations and floatingpoint additions. Simply extending the operand width a...

Reconfigurable computing offers the embedded systems designers the flexibility of application specific optimizations on a generic platform. In this paper, we are concerned with a fine-grain, tightly coupled, dynamically reconfigurable architecture we call Adaptive EPIC. A generic EPIC architecture is augmented with a dynamically reconfigurable structure. In this paper, we describe an experiment...

Speedups from mapping four real-life DSP applications on an embedded system-on-chip that couples coarsegrained reconfigurable logic with an instruction-set processor are presented. The reconfigurable logic is realized by a 2-Dimensional Array of Processing Elements. A design flow for improving application’s performance is proposed. Critical software parts, called kernels, are accelerated on the...

Three technologies must be advanced to enable the migration of reconfigurable computing from research to security and safety critical applications. Those technologies are rapid dynamic reconfiguration, multiple user support, and secure application separation. All three technologies are necessary to meet the requirements of future avionics, security, and defense applications. In this paper, we p...

Application-specific circuits are used to migrate computer systems from workstations to handheld devices that need real-time performance within the budget for physical size and energy dissipation. However, these circuits are inflexible as any modification requires redesign and refabrication, which is both expensive and time-consuming considering the complexity of recent embedded platforms. Ther...

RMS may be applied to manufacturing systems for large volume production, such as those used in the auto industry, and can be applied to a small cell of machines, or even to a single machine. The concept in all these applications is the same – purchase exactly the equipment that you need, with the option to change it exactly when your needs will change. Changes may be in the functionality of the...

Reconfigurable computing (RC) applications have the potential for significant performance while consuming little power. Although runtime performance analysis of RC applications has previously been shown to be important in achieving this potential, the optimization process is still arduous. We target two primary contributing factors: the incongruence between traditional CPU-based performance vis...

We describe an algorithm to compute the geodesics in an arbitrary CAT(0) cubical complex. A key tool is a correspondence between cubical complexes of global non-positive curvature and posets with inconsistent pairs. This correspondence also gives an explicit realization of such a complex as the state complex of a reconfigurable system, and a way to embed any interval in the integer lattice cubi...
