Devices in which microprocessors used

Additionally, RISC microprocessors have more registers, use more RAM, and use a fixed number of clock cycles to execute one instruction. Their purpose is to reduce the number of instructions for each program. The number of cycles per instruction is ignored. Because complex instructions are made directly into the hardware, CISC microprocessors are more complex and slower. CISC microprocessors use little RAM, have more transistors, have fewer registers, have numerous clock cycles for each instruction, and have a variety of addressing modes.

Some microprocessors are built to perform specific functions. For example, coprocessors are used in combination with a main processor, while a transputer is a transistor computer: a microprocessor that has its own local memory. CPUs used to be enormous. It wasn't until the s that designers were attempting to integrate the functions of a CPU onto microprocessor units.

It was the successful development of the microprocessor that led to the home computer. General purpose microprocessors are what allows our computers to be used for text editing, multimedia display, computation, and communication over the Internet. Because of how fast, small, and energy-efficient they are, they have been integral to the development of everyday technology, including appliances, smartphones, and more.

Since the microprocessor basically changed the world, it's worth understanding what it is and how it functions!

Microprocessors then incorporated all this into one or a few large-scale ICs. The integration of a whole CPU onto a single or a few integrated circuits significantly reduced the cost of processing power.

Typically, integrated circuit processors are manufactured in large numbers by highly automated metal-oxide-semiconductor MOS fabrication processes, resulting in a low unit price. Single-chip processors increase reliability since there are fewer electrical connections that could fail. This too has added to the popularity of microprocessors. And it explains why other forms of computers have been rendered almost completely obsolete. Microprocessors are a mass storage device and they are also an advanced form of computer, which is why they are also called microcomputers.

The availability of low cost, low power and small weight, computing capability makes these microprocessors greatly useful in several applications. One or more microprocessors are used today in everything from the smallest embedded systems and handheld devices to the largest mainframes and supercomputers.

Microprocessor-based systems are thus found everywhere today and not just in computers and smartphones: in automatic testing of products, speed control of motors, traffic light control, communication equipment, television, satellite communication, home appliances, such as microwave oven, washing machine, gaming controller, industrial controllers and even specialised applications such as military applications.

We shall now take a look at the leading microprocessors across four key categories :. Today, handheld devices - this includes smartphones, tablets, portable media players - have rather powerful microprocessors, so much so that they can compete with a desktop computer.

And processors are these days are coming up with more cores. Initially, processors were single core, followed by two cores, Quad-core, Hexa-core, Octa-core and now even Deca cores. Most processors nowadays are 64bit. With Graphics Processing Unit GPU being included inside mobile processors, these devices can now offer high quality graphics, Virtual Reality capability, 3D capability and 4k recording, plus the improved processor technology means greater power efficiency.

Leading manufacturers under this category are MediaTek and Intel. ARM assembly code is composed of many small instructions instead of fewer but more complex instructions, and ARM does not have any unnecessary or complicated features, making these chips simpler to build.

We could set the washing machine to wash and then dry our clothes while we read a book or watch a movie. Other ways in which microprocessors can affect how we spend our leisure time are listed below:. Positive effects of microprocessor-controlled devices on leisure time:. For example: I could complete my work for the evening using a laptop on the train.

This means I don't have to do it when I get home. Microprocessors in household appliances can make sure that the task is completed without you actually being there.

Once you have started the appliance you can go off and sky dive Because microprocessor-controlled devices can reduce the amount of time it takes us to complete our every-day tasks we are left with more free time.

Some people choose to spend some of this extra time in the gym getting fit. Extra leisure time can be spent watching t. With microprocessor-controlled devices taking care of household chores, people are freed up to tackle more work-related tasks.

For example: A businessperson could email clients while an intelligent oven cooks their dinner to perfection. Negative effects of microprocessor-controlled devices on leisure time:.

When devices do a lot of our tasks for us it is easy to become lazy. For example: Instead of vacuuming the floor I could let a robotic vacuum do the job while I go sit and eat ice-cream.

Because microprocessor-controlled devices do most of the work for us it means that we are not doing as much hard manual work as we used to. For example: Before we had washing machines, doing the laundry was actually quite a demanding task. You had to wash the clothes by hand and then hang them on a washing line. Now all we need to do it put them in the machine and press 'go'. Here are some links to videos that discuss some of the microprocessor-controlled topics discussed above:.

Microprocessor-controlled devices like computers and mobile phones have made it easier for use to contact and stay in touch with friends and family. Mobile phones make it easy to interact with people.

VoIP services offer cheap calls around the world. Emails can be used to interact and talk to people. ICT allows the elderly and disabled an easy way to interact with loved ones.

Over-reliance on ICT to interact can lead to social isolation not having actual physical friendships. Mobile phones allow us many ways in which to interact or chat to friends and family. Blackberry Messenger - BBM.

Social networking sites are growing more and more popular as a way to keep in contact with friends. Facebook alone has 1 billion active users. These sites have many ways in which you can interact including: Private Messaging Status Updates Commenting on images or statuses. VoIP Services like Skype :. Skype is a 'VoIP' voice over Internet protocol service which allows you to make very cheap phone calls over the Internet.

Skype is especially useful if you want to talk to someone in another country as the prices are very cheap, no matter how far apart you are. Good old emails are still sent in their billions. They are quick and easy and allow us to send and receive messages , no matter where we are in the world, at the click of a button. Emailing can now be carried out on the move thanks to portable devices like mobile phones, IPads and laptops and Wi-Fi. Positive and negative effects of microprocessor-controlled devices on social interaction:.

The table below summarises some of the positives and negatives of ICT on how we interact socially:. Positive effects:. Negative effects:. Easy to make new friends in chat-rooms , social networking sites or while playing online computer games. You don't actually meet people face to face as much.
