Designing efficient input interconnect blocks for LUT clusters using counting and entropy

Proceedings of the 2007 ACM/SIGDA 15th international symposium on Field programmable gate arrays, 2007
In a cluster-based FPGA, the interconnect from external routing tracks and cluster feedbacks to the LUT inputs consumes significant area, and no consensus has emerged among different implementations (e.g., 1-level or 2-level). In this paper, we model this interconnect as a unified input interconnect block (IIB).

Exact tree-based FPGA technology mapping for logic blocks with independent LUTs

Proceedings 1998 Design and Automation Conference. 35th DAC. (Cat. No.98CH36175), 1998
The logic blocks (CLBs) of a lookup table (LUT) based FPGA consist of one or more LUTs, possibly of different sizes. In this paper, we focus on technology mapping for CLBs with several independent LUTs of two different sizes (called ICLBs). The Actel ES6500 family is an example of a class of commercially available ICLBs.

Modeling the Arithmetic Decomposition of DA-LUT Block for Heterogeneous FPGA Structures

International Journal of Electronics and Telecommunications, 2012
Abstract Distributed arithmetic is well known technique of designing FIR filters in FPGA devices. The quality of such filter implementation strongly depends on synthesis results of the DALUT block. Heterogeneity of modern FPGA structures introduces new possibilities into implementation process, that may lead to better results, but also makes it ...

Reflections on the rigidity of the Lut Block and recent crustal deformation in eastern Iran

Tectonophysics, 1975
Abstract Imagery from the first Earth Resources Technology Satellite passes over east-central Iran are interpreted with special emphasis on geomorphology of the structural trends in the area. Several units of arcuate structure are named and discussed.

Boolean matching for LUT-based logic blocks with applications to architecture evaluation and technology mapping

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2001
In this paper, we present new Boolean matching methods for lookup table (LUT)-based programmable logic blocks (PLBs) and their applications to PLB architecture evaluations and field programmable gate array (FPGA) technology mapping. Our Boolean matching methods, which are based on functional decomposition operations, can characterize functions for ...

Analysis of FPGA Architecture with Hybrid Logic Blocks Based on ULG and LUT

Journal of Circuits, Systems and Computers
This paper analyzes the efficiency of different FPGA architectures consisting of Hybrid logic blocks (HLB) formed with Look-up Tables (LUTs) and Universal Logic Gates (ULGs). Pure LUT-based architectures induce area overhead and a longer delay. A ULG is designed to realize an efficient architecture compared to pure LUT-based architectures.

Geometric-kinematic characteristics of the main faults in the W-SW of the Lut Block (SE Iran)

Journal of African Earth Sciences, 2018
Abstract The area to the W-SW of the Lut Block in Iran has experienced numerous historical and recent destructive earthquakes. We examined a number of faults in this area that have high potential for generating destructive earthquakes. In this study a number of faults are introduced and named for the first time.

Petrography, geochemistry and tectonic significance of the Mahoor granitoids (Lut Block, Eastern Iran)

2014
The Mahoor granitoids are Cu–Zn-bearing porphyries that outcrop in the central part of the Lut Block, about 135 km south-west of Nehbandan (eastern Iran). These granitoids occur mainly as dykes and stocks that intrude Eocene volcanics. Petrographically, all the studied intrusives display porphyritic textures with mm-sized phenocrysts, most commonly of ...
