چکیده

Computerised Tomography (CT) refers to the process that generates a cross-sectional or volumetric image of an object from a series of projections collected by scanning the object from many different directions [1]. Due to the essential complex feature of filtered backprojection (FBP) algorithm, image reconstruction is a computationally intensive process. Thanks to reconfigurable technology, algorithms implemented on FPGA offer significant speedup for computationally intensive signal and image processing algorithms. Our implementation on FPGA shows approximately 35 times speedup over software version of the same algorithm running on a 2.8 GHz Pentium PC and the speedup can be further enhanced by choosing fixed-point arithmetic and higher bandwidth DDR SDRAM. Our solutions can be applied to a wider range of application areas where computationally intensive algorithms are required.

Layout Design of a Furniture Production Line Using Formal Methods

This paper experiments application of different heuristic approaches to a real facility layout problem at a furniture manufacturing company. All the models are compared using AHP, where a number of parameters of interest are employed. The experiment shows that formal layout modelling approaches can be effectively used real problems faced in industry, leading to significant improvements.

An Agile Migration Framework for Analog Layout Design

Layout generation in the late analog CMOS design is challenging by its increasing layout constraints and performance requirements. However, iterative refinement on manual design damages the productivity of analog layout. Therefore, it is more efficient to enroll the know-how from existing design instead of generating a new one. To contend with time-consuming analog layout for more possibilities...

An efficient approach for solving layout problems

This paper offers an approach that could be useful for diverse types of layout problems or even area allocation problems. By this approach there is no need to large number of discrete variables and only by few continues variables large-scale layout problems could be solved in polynomial time. This is resulted from dividing area into discrete and continuous dimensions. Also defining decision var...
