2013 Honda Civic

August 16th, 2010

To know about upcoming 2013 Honda Civic is the most sought out thing in recent days, so we are here to discuss about this new Honda model. The people are more curious about knowing what will be the features and what are the new technologies placed in 2013 Honda Civic and hybrid versions will be most of users try to know, so we will estimate from previous versions of Honda Civic.

2013 Honda Civic estimated to be coming with some new features and most of the features will be taken from its previous versions and customers who experienced previous Honda models can be estimate about new one easily because big changes cant be kept in this upcoming model or a mere study can bring them to a position to estimate the 2013 Honda Civic. But there are so many features that can decide the position of upcoming Honda Civic in the market and one of them is Fuel Economy the most sought out thing for any customer for any car, so what the 2013 Honda Civic offering we can estimate. Here also there will not be huge changes in from its previous ones, so by estimating from present model, the present model of 4 cylinder versions are giving a range of 26 miles per gallon in city and 34 miles per gallon on highway and Honda will try to increase these figures because in future gas prices are going to increase so fuel based cars will be more concerned among customers.

Honda company will be watching its rivals for 2013 Honda Civic model, and they will try to reach our out of reach to their competitors. Our estimation about 2013 Honda Civic competitors are Ford Focus, Mitsubishi Lancer and Chevy Cobalt and some other models and even customer can calculate to his knowledge and can find which one best suit for his desire. Honda will give full features into 2013 Honda Civic to give stiff competition for other rival models, Honda civic is best know for huge horse power feature, quality and much more. Even Honda has better resale value than other model cars so this will also add to increase the chances of favoring Honda Civic.

Going to pricing aspect of 2013 Honda Civic, estimations are going around and our estimations are taken from the previous ones studies. Pricing is the most concern thing for any customer and they will judge the car by there calculated amount and Honda is rated high among any cars in market and this will make the pricing high because of high demand. Pricing estimations of 2013 Honda Civic can be done by taking present and previous versions, the 2010 Honda Civic priced around $15,655 and 16,405 for manual transmission version and for automatic transmission version respectively. Then going to most high sales model i.e. LX model, it is priced around $17,600 and $ 18,200 for manual transmission version and for automatic transmission version respectively.

Thinking of when to own the 2013 Honda Civic, so then see here. The previous versions of Honda Civic are released in middle of the year in which the model displayed earlier months. So this time also the 2013 Honda Civic will hit the market in US around August or September 2012. Surprises can be coming unnoticed so be updated so that you don’t miss any opportunity.

Arecord

August 3rd, 2010

Arecord is used to record a sound file in the Linux. The typical command for recording  a sound  in the Linux is as follows

arecord filename.wav

where filename.wav is the name of the file where the recorded file will be saved.  The recorded file can be played using the aplay command.

The arecord and the aplay commands togather form the conjugate for recording and playing sound file for the alsamixer driver.

The complete syntax of the arecord  linux command has several options. You may like to refer to the linux manual to read more about it.

In computer language, arecord is also used to represend another thing. More often called A record, it  gives you the IP address corresponding to domain

aplay

August 3rd, 2010

If you wish to play an audio file on a linux, you can use the aplay command. The alpaly command  is used to the ALSA sound driver.

Several different file fomats are supported using the aply command. In its simplest format, you  can play a wave fie using a command like

aplay x1.wav

where x1.wav is the name of the file being played. It can be a previously generated and stored  file or a file created using the arecord command.

The aplay command is capable of playing several different formats of the sound file. It gets the  information about the supported file from the header of the file. The typical data it gathers  include sample rate and the bit size.

If you need help at any time with the aplay command you can just use

aplay -h.

A number of flags can be used in the aplay command. YOu may refer to the linux manual for  complete detail.

Alsamixer

August 3rd, 2010

ALSA stands for Advanced Linux Sound Architecture. The alsamixer is a semi graphical representation of the commands showing pictorial views of the mixer. Using alsamixer you can set the level of the Audio output, set or turn off the microphone and adjust the level of the side tone to name few of its functions.

The alsamixer does not require any windows system and still, its graphical representation are reasonably intuitive using ncurses interface.

If you are using a remote login using secure CRT, make sure that you select the Emulation termila type as Linux and check the ANSI color. This will give the colored interface and makes the things very intuitive.

If alsamixer is installed, then, if you give the command

#alsamixer

Difference Between DDR2 and DDR3

July 30th, 2010

Here is a question and answer between DDR2 and DDR3

Question – Which one is faster DDR2 or DDR3 ?

Answer – Obviously DDR3 idiot. That is why it was designed for. A lot of money went into its design and implementation. Without any speed gain what would have been purpose of it.

Question – Thanks for clarifying it. So DDR3-800 is faster than DDr2-800 right.

Answer – No DDR3-800 is slower than DDR2-800. Actually higher speed grades of DDR3 is faster than DDR2-800

Question – But you said DDR3 is faster than DDR2 just now.

Answer – Yes I did, but DDR3 must be much faster in speed than DDR2 in order that the throughput difference will be visible. For example DDR3-1333 is faster than DDR2-800.

DDR3 and Signal Integrity

July 29th, 2010

DDR3 improves upon the speed over DDR2. While DDR2 works upto a maximum JEDEC supported frequency of 800 MBps, DDR3 can work upto 1600 Mbps. The Speed increase, however, does not lead to the linear increase in the throughput owing to the increase in the cache latency.

DDR3 leads to several design challenges in maintaining the Integrity of the Signal on the PCB. Its operating voltage has been reduced from 1.8V to 1.5V leading to 17% reduction in the voltage and c lose to 25% reduction in the power consumption.

Its partial refresh feature which is used to refresh only the active part of the DRAM while in sleep mode further improves the battery performance.

From the topology point of view DDR3 utilizes dynamic on-die termination (ODT), ZQ calibration, and a fly-topology all designed to improve signal integrity. In the On die termination, the termination resistors are placed on the chip itself rather than that on the PCB outside the chip.  By Dynamic on die termination we mean that we can change the termination on the fly as required. The ZQ calibration command is used to calibrate the driver  impedance and the termination resistance value which takes care of the process variation due to temperature, voltage or the board discontinuity.

The topology of the  address and control lines in DDR3 chain from one DRAM to another, unlike DDR2 uses a T topology. This however, introduces skew between the signals.
