Technology mapping algorithms for LUT (Look Up Table) based FPGAs have been proposed to transfer a Boolean network into logic-blocks. However, since those algorithms take no layout information into account, they do not always lead to excellent results. In this paper, a simultaneous technology mapping, placement and global routing algorithm for FPGAs, Maple, is presented. Maple is an extended ve...

In permanent magnet motors, the stator resistance and magnetic flux of change as temperature increases. These changes result in a maximum torque point per unit ampere (MTPA) motor. Without adequate compensation, this leads to decrease output torque. For reason, look-up table (LUTs) are prepared over range used for interpolation. This paper proposes method compensate reduction due increase using...

The main required organ of the biological system is Central Nervous System (CNS), which can influence other basic organs in human body. elements this important are neurons, synapses, and glias (such as astrocytes, highest percentage brain). Investigating, modeling, simulation, hardware implementation (realization) different parts CNS case achieving a comprehensive neuronal that capable emulatin...

A filter cache is proposed at a higher level than the L1 (main) cache in the memory hierarchy and is much smaller. The typical size of filter cache is of the order of 512 Bytes. Prediction algorithms popularly based upon the Next Fetch Prediction Table (NFPT) helps making the choice between the filter cache and the main cache. In this paper we introduce a new prediction mechanism for predicting...

High performance multiplier designs are the prime need of emerging digital filtering operations. This research study presents a novel architecture of reduced area computation sharing multiplier for Finite Impulse Response (FIR) filter. The same architecture is extended for the floating point applications. The chosen precomputer alphabet set is the most prominent feature of this architecture. Th...

With continued scaling of silicon process technology, producing reliable electronic components in extremely denser technologies pose a challenge. Further, the systems fabricated in deep sub-micron technology are prone to intermittent or transient faults, causing unidirectional errors, upon exposure to ionizing radiations during system operation. The ability to operate in the intended manner eve...

This paper proposes a novel direct torque and reactive power control (DTC) for grid-connected doubly fed induction generators (DFIGs) in the wind power generation applications. The proposed DTC strategy employs a variable structure control (VSC) scheme to calculate the required rotor control voltage directly and to eliminate the instantaneous errors of active and reactive powers without involvi...

Arithmetic encoding is an essential class of coding techniques which have been widely used in various data compression systems and exhibited promising performance. One key issue of arithmetic encoding method is to predict the probability of the current symbol to be encoded from its context, i.e., the preceding encoded symbols, which usually can be executed by building a look-up table (LUT). How...

Classification of network traffic is basic and essential for many network researches and managements. With the rapid development of peer-to-peer (P2P) application using dynamic port disguising techniques and encryption to avoid detection, port-based and simple payload-based network traffic classification methods were diminished. An alternative method based on statistics and machine learning had...

The recently launched Chinese GaoFen-4 (GF4) satellite provides valuable information to obtain geophysical parameters describing conditions in the atmosphere and at the Earth’s surface. The surface reflectance is an important parameter for the estimation of other remote sensing parameters linked to the eco-environment, atmosphere environment and energy balance. One of the key issues to achieve ...
