LAPLUS is a novel switch algorithm for flow control of the available bit rate (ABR) asynchronous transfer mode (ATM) service. It ensures a steady-state rate allocation satisfying the MCR-plus-equal-share criterion. It only requires constant-time processing and two tags to be stored per flow. It is naturally able to take peak cell rates of flows into account. LAPLUS solves in a novel way the problem of selecting a measurement interval. The solution allows it to contain queue growth and keep utilization high on one hand and control low speed flows and operate with stability on the other. We describe results of simulation study of LAPLUS. The results show it to be fair, responsive and stable.

A system called SYCLOP that synthesizes finite-state machines (FSMs) and combinational logic for low-power applications is presented. SYCLOP tries to minimize the area and the transition density at the internal nodes of a CMOS circuit. The minimization is based on the input signal probabilities and the transition densities. Using this system, a particular circuit can be optimally synthesized for different applications. Results have been obtained for a wide range of benchmark examples.>

CLAY takes a netlist partitioned down to the transistor level, a technology file with an arbitrary number of metal layers, and constraints on aspect and I/O signal positions to produce mask geometries. CLAY attempts to capture, in software, layout knowledge at the transistor level (allowing variable-shaped cells including heights) and at the floorplan level for VLSI sized examples. CLAY compares well with standard cell and manual approaches.>
