    A modified Earle latch, that requires only one copy of the input data instead of the two copies required in the original Earle scheme is presented. In SPICE simulations, the modified Earle latch has the smallest area and lowest power dissipation compared to other static latches. Chip implementation shows that the speed of an adder using the proposed latch outputs can be improved from 33 MHz to 60 ... View full abstract»

    To maximise device utilisation, a heterogeneous field programmable gate array (FPGA) provides either an array of homogeneous lookup tables (LUTs) of different sizes or an array of physically heterogeneous LUTs. It is shown that heterogeneous FPGAs have a significant number of desirable attributes. A technology mapping algorithm is proposed for heterogeneous FPGAs. The technology mapping problem is...

    In order to make computer-aided control systems as safe as possible, a number of analysis techniques have been developed. One of these is fault tree analysis. A fault tree (FT) represents causal and generalisation relations between events (e.g. a hazard and its causes). However, it can express neither time relations between events nor detection and protection times. Time Petri nets (TPNs) can mode... View full abstract»

    The authors describe the self-diagnostic tools of the APEmille SIMD machine, whose logical architecture is a three-dimensional torus of processors. The tools are aimed at implementing system-level diagnosis using a comparison model. The diagnostic model accounts for some critical features of the APEmille architecture, and has been validated by means of VHDL simulation. Essentially, diagnostic tool... View full abstract»
