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...

The paper focuses on the use of field programmable gate arrays (FPGA) for signal processing applications. By allowing designers to create circuit architectures developed for the specific applications, high levels of performance can be achieved using FPGA for many digital signal processing (DSP) applications providing considerable improvements over conventional microprocessor and dedicated DSP p...

Currently, the Computer-Aided Engineering (CAE) environments for designing Field-Programmable Gate Arrays (FPGAs) do not support the simulation of FPGA reprogrammability, hence prototyping of adaptive systems relies upon using the actual FPGAs. The FPGA architecture baselined in this paper, similar to a commercially-available FPGA architecture, supports partial reconnguration without disturbing...

In this paper we present a self con gurable multiplication technique allowing vari able con guration time for a class of LUT based Field Programmable Gate Arrays FPGAs which exist today We show this technique to be implementable on FPGA architectures allowing internally addressable RAM primitives to be directly mapped to the Logic Elements LEs of the logic resource This provides run time read w...

The role of Chip Implementation Center (CIC), founded in 1992 under the National Science Council (NSC) of Taiwan R.O.C., is to provide the services for the fabrication of multi-project chip (MPC), the procurement/integration of software CAD tools, and the promotion of IC and FPGA design/testing/CAD software technology for academia in Taiwan. To date, CIC assisted 86 universities and polytechnic...

In this paper, we present a novel temporal partitioning methodology for dynamically reconfigurable computing systems to reduce the communication costs of the design. This aim can be reached by minimizing the transfer of data required between design partitions. Our algorithm use the network flow-based multi-way task partitioning algorithm to minimize communication costs for temporal partitioning...

Truncated multiplier is a good candidate for digital signal processing (DSP) applications including finite impulse response (FIR) and discrete cosine transform (DCT). Through truncated multiplier a significant reduction in Field Programmable Gate Array (FPGA) resources can be achieved.
