摘要： A method for mapping moments in a reduced order system of approximation order q for use in simulating a circuit or system having n state variables at n nodes, the circuit or system having I inputs. The method includes calculating only q+I moments, where q is the approximation order and I is the number of inputs of the circuit or system being simulated, sorting the state variables at the n nodes, selecting q nodes of the n nodes, and calculating the dominate poles and zeros using a multi-point moment matching algorithm to simultaneously match q+I moments at the selected q nodes of the circuit or system. In one embodiment, the method includes using extra dummy inputs such that the total number of inputs equals I, such that K*I>q where K is a constant having a value in the range of about 4 to 8.

摘要： Transfer functions are calculated in the following manner within an RLC tree having a input and a plurality of nodes. The RLC tree is divided into left and right sub-trees joined by the node closest to the input. Each of the left and right sub-trees is divided into left and right sub-trees joined by a node. The sub-trees are divided recursively into still smaller sub-trees until the RLC tree is completely decomposed into left and right sub-trees joined by nodes. At each node of the RLC tree, the numerator and denominator of the transfer function at that node are determined in accordance with the left and right sub-trees joined by that node. The denominator of the transfer function of the node closest to the input is taken to be the denominator of all of the transfer functions of the RLC tree. For each node, the numerators of the transfer functions of the left and right sub-trees joined at that node are corrected in accordance with the denominators of the transfer functions of the left and right sub-trees joined at that node.

摘要： Certain embodiments provide systems and methods for reducing power consumption in on-chip caches. Certain embodiments include Power Density-Minimized Architecture (PMA) and Block Permutation Scheme (BPS) for thermal management of on-chip caches. Instead of turning off entire banks, PMA architecture spreads out active parts in a cache bank by turning off alternating rows in a bank. This reduces the power density of the active parts in the cache, which then lowers the junction temperature. The drop in the temperature results in energy savings from the remaining active parts of the cache. BPS aims to maximize the physical distance between the logically consecutive blocks of the cache. Since there is spatial locality in caches, this distribution results in an increase in the distance between hot spots, thereby reducing the peak temperature. The drop in the peak temperature then results in a leakage power reduction in the cache.
