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...
This paper presents a hardware approach to performing accurate floating point addition and multiplication using the idea of errorfree transformations. Specialized iterative algorithms are implemented for computing arbitrarily accurate sums and dot products. The results of a Xilinx Virtex 6 implementation are given, area and performance are compared against standard floating point units and it i...
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. This paper presents for the first time a comparison of resource utilization of Spartan-3AN and Virtex-5 implem...
This article presents an asynchronous FPGA architecture for implementing cryptographic algorithms secured against physical cryptanalysis. We discuss the suitability of asynchronous reconfigurable architectures for such applications before proceeding to model the side channel and defining our objectives. The logic block architecture is presented in detail. We discuss several solutions for the in...
Lower/Upper triangular (LU) factorization plays an important role in scientific and high performance computing. This paper presents an implementation of the LU decomposition algorithm for double precision complex numbers on a star topology based multi-FPGA platform. The out of core implementation moves data through multiple levels of a hierarchical memory system (hard disk, DDR SDRAMs and FPGA ...
Manipulating configurable resources like FPGAs in a codesign framework has become essential: especially, FPGAs may efficiently implement parallel systematic signal processing tasks. Nevertheless, such implementations are usually hand written at a low level. Our proposition is to provide high level modeling of an application and tools to automatically generate tuned VHDL code from these high lev...
