This paper focuses on the algorithm which can be very efficient for the purpose to minimize the delays introduced in the circuit because of placement and routing. Placing and routing operations are performed when an FPGA device is used for implementation. The delay introduced by logic block and the delay introduced by interconnection can be analyzed by the use of efficient place and route algorithm...
In this paper, we study the effect of using digitally controlled impedance IO Standard in memory interface design in terms of power consumption. In this work, we achieved 50% dynamic power reduction at 1.5V output driver voltage, 35.2% dynamic power reduction at 1.8V output driver voltage in comparison to 2.5V output driver voltage in DCI based IO standard implementation on input or output port in...
Defining the hardware in terms of software is our main motto, In this era of wireless technology it is quite common for rapid change of technology and communication standards, As a result, when technology changes, changes in its circuit Architecture will takes place, so there is a need to design new architecture to use the new technology, In order to design, test and manufacture this new technology,...
Viterbi Decoders are employed in digital wireless communication systems to decode the convolution codes which are the forward error correcting codes. Although widely-used, the most popular communications decoding algorithm, the Viterbi Algorithm (VA), requires an exponential increase in hardware complexity to achieve greater decode accuracy. When the applications based with wireless technology has...
Frequency-hopping is a method by which the carrier of a transmitting radio signal will rapidly switch among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. This rapid switching of the carrier frequencies during transmission will minimize the unauthorized interception or jamming of telecommunications. Any radio with a digitally controllable frequency synthesizer...
The nonlinearity of a Power amplifier creates spectral growth beyond a specific bandwidth which interferes with adjacent channels. This nonlinearity also causes in-band distortion which will affect the Bit error rate performance, so Linearization of power amplifiers is very essential for reliable transmission. Digital Pre-distortion (DPD) is a linearization technique which will negate the non-linear...
H.264, which is the most advanced video compression standard till date, includes novel algorithms for quantization and inverse quantization processes. In this paper, a new hardware architecture exclusively based on combinational logic is proposed for the quantizer and inverse quantizer blocks for real-time video processing. Implemented in Xilinx14.1, Virtex-5 technology, the proposed architectures...
With the continuous decrease in the minimum feature size and increase in the chip density due to technology scaling on-chip memories are becoming increasingly susceptible to multi-bit soft errors due to single or multiple event upsets caused by environmental factors such as cosmic rays, neutrons particles. The increase in multi-bit errors could lead to higher risk of data corruption and even catastrophic...
