power amplifiers (pas) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. although most existing architectures assume that the pa has a memoryless nonlinearity, memory effects of the pas in many applications ,such as wideband code-division multiple access (wcdma) or orthogonal frequency-division multiplexing (ofdm), can no longer b...

in this paper an application of cellular learning automata (cla) to vlsi placement is presented. the cla, which is introduced for the first time in this paper, is different from standard cellular learning automata in two respects. it has input and the cell neighborhood varies during the operation of cla. the proposed cla based algorithm for vlsi placement is tested on number of placement proble...

Reconfigurable processors, like the Field Programmable Gate Arrays (FPGA's), open new computational paradigms where the processor is able to tailor its internal structure to better . implement a given application. A typical FPGA consists of an array of configurable logic blocks and a mesh of interconnections fully programmable by the user to perform a given application. By just changing its int...

Abstract This paper presents a new stochastic model for two dimensional layouts of large size. Two problems are addressed: (i) Under the condition that the number of wires emanating from a block is Poisson distributed, determine the distribution of channel width, thus estimating the average channel width. (ii) Given T tracks for each channel, determine the success probability of routing an M×M ...

A new Field Programmable Gate Array (FPGA) architecture is described. This architecture includes a number of novel features not found in currently available FPGAs. It is believed to ooer a signii-cantly improved logic density in some common applications. This paper describes the development of the FPGA and looks at the mapping onto it of some interesting application circuit elements. The design...
