It is difficult for LUT-based FPGA technology mapping to generate a power-minimal K-input LUT network with minimum depth at one time because a problem for power-minimization was shown to be NP-hard[5]. A problem for area-minimization is also NP-hard, and area-aware algorithms[7][8][9][10] recover area after generating a depthminimum network. On the other hand, existing poweraware algorithms[11]...

Due to wide power spectrums of rectangular data streams, it is important for base-band signals to be heavily band limited before modulation. That can be achieved by pulse shaping of rectangular bits. Some of the most common are a half-sine pulse shaper and a Gaussian pulse shaper which are used in Minimum Shift Keying (MSK), Gaussian Minimum Shift Keying (GMSK) and Gaussian Frequency Shift Keyi...

DCT-based digital video coding standards such as MPEG and H.26x have been widely adopted for multimedia applications. Thus video processing in the DCT domain usually proves to be more ef£cient than in the spatial domain. To directly convert an inter-coded frame into an intra-coded frame in the DCT domain, the problem of DCT domain inverse motion compensation was studied in [1]. Since the data i...

This paper elucidates the system construct of DA-FIR filter optimized for design distributed arithmetic (DA) finite impulse response (FIR) and is based on architecture with tightly coupled co-processor data processing units. With a series look-up-table (LUT) accesses in order to emulate multiply accumulate operations constructed DA FIR implemented FPGA. The very high speed integrated circuit ha...

Lower urinary tract (LUT) symptoms become prevalent with aging and affect millions; however, therapy is often ineffective because the etiology is unknown. Existing assays of LUT function in animal models are often invasive; however, a noninvasive assay is required to study symptom progression and determine genetic correlates. Here, we present a spontaneous voiding assay that is simple, reproduc...

In this paper, we present the condition for the effective wire addition in Look-Up-Table-based (LUT-based) field programmable gate array (FPGA) circuits, and an optimization procedure utilizing the effective wire addition. Each wire has different characteristics, such as delay and power dissipation. Therefore, the replacement of one critical wire for the circuit performance with many non-critic...

Abstract: In this paper, a highly area-efficient multiplier-less FIR filter is presented. Distributed Arithmetic (DA) has been used to implement a bit-serial scheme of a general asymmetric version of an FIR filter, taking optimal advantage of the 3-input LUT-based structure of FPGAs. The implementation of FIR filters on FPGA based on traditional arithmetic method costs considerable hardware res...

The Lut block in eastern Iran is a micro-continental block within the convergent orogen between the Arabian, Eurasian and Indian plates. Large areas of the north-central, eastern, and western Lut block are covered by volcanic rocks of Paleogene, Neogene and Quaternary age.  Peak volcanic activity took place in the north-central part of the Lut block during the Eocene, and then dramatically decr...

Approximating while compressing lookup tables (LUT) with a set of neural networks (NN) is an emerging trend in safety critical systems, such as control/command or navigation systems. Recently, example, many research papers have focused on the ACAS Xu LUT compression. In this work, we explore how to make compression preserving system and offering adequate means certification.

The Solar Diffuser (SD) is used for the MODIS reflective solar bands (RSB) calibration. An on-board Solar Diffuser Stability Monitor (SDSM) tracks the degradation of its on-orbit bi-directional reflectance factor (BRF). To best match the SDSM detector signals from its Sun view and SD view, a fixed attenuation screen is placed in its Sun view path, where the responses show ripples up to 10%, muc...
