This paper describes the development of a novel Xilinx XC6264 FPGA configuration control mechanism implemented within the CLC array of an XC6264 FPGA. The mechanism allows CLC configured logic to select the next active configuration of the XC6264 and invoke dynamic reconfiguration. This mechanism has been developed within a hybrid multi-role prototype platform consisting of TIM-40 standard parallel processors and custom designed XC6200 FPGA resource peripheral card. Using this system dynamic coprocessor and stand-alone self-configurable applications have been devised. To further this work the preliminary specification of a novel Asynchronous Virtual Instruction Set Computer is also presented.

The Virtex user-programmable gate array, shown in Figure 1, comprises two major configurable elements: configurable logic blocks (CLBs) and input/output blocks (IOBs). • CLBs provide the functional elements for constructing logic • IOBs provide the interface between the package pins and the CLBs

tables than mis-pga [Murg90a] to implement a set of benchmark networks. Chortle-crf can also implement a network as a circuit of Xilinx 3000 series Configurable Logic Blocks (CLBS). To implement the benchmark networks as circuits of CLBS Chortle-crf requires 12 70 fewer CLBS than mis-pga and 22 % fewer

Blocks (CLBs), i.e. CLBs that are part of an implemented function that is actually being used by the system, releasing it to be tested in a way that is completely transparent to the system.

Abstract—This paper presents the design and simulation of a circuit consisting of multiple interacting configurable logic blocks (CLBs) using quantum-dot cellular automata (QCA). Previous work on QCA-based field-programmable gate arrays (FPGAs) has focused on fixed logic and programmable

The process of formation and degeneration of concentric lamellar bodies (CLBs) in axon termi-nals and preterminal axons of Purkinje cells were examined by acid phosphatase (ACPase) cytochemistry. In myelinated axons, tubular structures measuring 20-50 rim in diameter contained ACPase reaction

). To satisfy requirements of different applications, many certificateless blind signature (CLBS) schemes using bilinear pairing for the CLPKC setting have been proposed. However, the bilinear pairing operation is very complicated. Therefore, the performance of those CLBS schemes is not very satisfactory

, and the industrial tools xnfmap for technology mapping and apr for automatic placement and routing. We measure the quality of the multi-level logic minimization tools by the number of routed configurable logic blocks (CLBs) in the FPGA realization. We report three results: a) there is a linear relationship between

, specific roles for individual Clbs have been difficult to assign. To help genetically define such roles, strains carrying a cdc28 ts allele, combined with single CLB deletions were studied. We assumed that by limiting the activity of the kinase, these strains would be rendered more sensitive to loss
