The single chip computer on the site runs the iPic web-server, the world’s tiniest implementation of a TCP/IP stack and a HTTP web-server. The TCP/IP stack and the webserver uses around 30 bytes of RAM. The code is written in C ideas that Miniweb uses: iPIC – A Match Head Sized Web Server. Additionally, tiny, inexpensive Web servers make the vision of a totally Shri said the iPic server has been online since the middle of July.

Toggle navigation Adam Dunkels. And he or she would not need specialized software, “a super-duper gizmo or an ipci wireless controller. This connection will hang until the application in the other end sends data. Home Code Science Talks Contact.

The PIC is about six millimetres square in size and costs roughly a dollar. As an example, someone who is forgetful, or merely fretful while traveling, could drop into an Internet cafe anywhere to check on the oven back home — and turn it off as well.

The number of lines of code are approximate. The code is written in C and constitutes around lines, comments removed. He says because the machine is a Web-server, it does not servdr a keyboard or display, but is operated from another computer using a Web connection. There are two variants of Miniweb, a stateless variant served a statefull variant.

The eventual applications of his discovery could be “phenomenal,” he says. Number of lines of code zerver RAM usage in the stateless Miniweb.

Is the device there? Until recently, only desktop computers or larger machines could be connected to the Internet as Web-servers. This compensation may impact how and where products appear on this site including, for example, the order in which they appear.

Thanks to a graduate student at an American university, the day when you may control every electrical device in your life with a web browser is a lot closer. And answer a lot of questions about his invention, and study offers from computer firms. This means that all the electrical devices in your house would be able to communicate with each other, and could be controlled from a home computer. A web server is a combination of software and hardware that makes information accessible on the world wide web.


Shrikumar is glad that after nearly six months of “going insane with this crazy hobby,” his brain is finally getting some rest. Some of the products that appear on this site are from companies from which QuinStreet receives compensation. Hariharasubrahmanian Shrikumar has made a web server out of a single microchip the size of a fingernail. Searching our resource database to find your matches With technology like the iPic they can be connected to common network facilities, instead of using dedicated wires and a dedicated control terminal, for each device or equipment.

To inspect the packets that are sent to and from Miniweb, run tcpdump -l -n -S -i tun0. The World’s Smallest Server Previous: His discovery could become a part of everyday life in homes across the world, he asserts.

The stateless Miniweb keeps only minimal state information.

Download the code and do: It is connected to the Internet through a serial port. Even though its software is less than half a kilobyte in size, the iPic is a fully functional web server that complies with international standards.

Imagine being able eeb check if you’ve left the oven on in your house from the other side of the world, and turn it off if you have. The previous title for the world’s smallest Web-server was held by a researcher at Ipi University.

This has prevented devices such as mobile phones from being easily connected to the internet.

iPic Web Server Aims to Make Toaster-Net a Reality

It also offers a detailed technical description of the device. The total RAM usage varies between 24 and 28 bytes depending on the number of bytes used for pointers on the system for which Miniweb is compiled. The chip is accessible through the internet herebut because the serial link is usually up to capacity, the ipjc are also mirrored here.

Traditionally, web servers have required microchips that are much larger, expensive and powerhungry than the iPic. At the office many industrial computers and wev are equipped with their own remote management facilities. He has reportedly has beaten many contenders including researchers at several big universities and corporations. The stateless variant is a bit smaller and uses less RAM, but does not provide the same functionality as the statefull variant.


Seriously, he says his father, S H Subrahmanian, a physics professor and his mother, Kokilamani who taught biology, had instilled in him from his childhood the ideals of tenacity. The tiny size and low power requirements of sserver iPic mean that it could conceivably be placed in any electrical device such as lights, alarm clocks or cameras. You have characters left. The checksum is computed when each byte is received and if the checksum is found to be incorrect when the entire packet has been received, the contents of the packet is not used for further processing.

Each of the appliances we use in offices and homes has its own array of buttons and indicators, he points out. At that rate it should be able to serve about hits per hour.

IPic – A Match Head Sized Web-Server

His Web-server has been shrunk about two orders of magnitude, becoming almost times smaller in physical size, and 1, times smaller in software size, he says. He recalls John Romkey, a well-known computer-networking researcher, predicting in that one day every toaster would be on the Net. In terms of technology, the achievement is not only in connecting a small computer on the Web, but also in the size of the network software that is running on the chip, he explains.
