    Memory for prose in Korsakoff and schizophrenic populations.
    (The International journal of neuroscience, 1981-01) Rubin, DC; Olson, EH; Richter, M; Butters, N
    Twelve alcoholic Korsakoff patients, their 12 alcoholic controls, and 27 institutionalized schizophrenics and their 19 controls, recalled two stories. The clinical populations recalled approximately half as much as their controls, yet recalled the same parts of the stories as their controls. For both groups the ability to process simple prose does not seem to be severely impaired when what is recalled rather than how much is recalled is measured.

    Test-Delivery Optimization in Manycore SOCs
    (2013-03-18) Agrawal, M; Richter, M; Chakrabarty, K
    We present two test-data delivery optimization algorithms for system on-chip (SOC) designs with hundreds of cores, where a network-on-chip (NOC) is used as the interconnection fabric. We first present an e ective algorithm based on a subsetsum formulation to solve the test-delivery problem in NOCs with arbitrary topology that use dedicated routing. We further propose an algorithm for the important class of NOCs with grid topology and XY routing. The proposed algorithm is the first to co-optimize the number of access points, access-point locations, pin distribution to access points, and assignment of cores to access points for optimal test resource utilization of such NOCs. Testtime minimization is modeled as an NOC partitioning problem and solved with dynamic programming in polynomial time. Both the proposed methods yield high-quality results and are scalable to large SOCs with many cores. We present results on synthetic grid topology NOC-based SOCs constructed using cores from the ITC’02 benchmark, and demonstrate the scalability of our approach for two SOCs of the future, one with nearly 1,000 cores and the other with 1,600 cores. Test scheduling under power constraints is also incorporated in the optimization framework.
