Computer engineering(CoEorCpE) is a branch ofcomputer scienceandelectronic engineeringthat integrates several fields ofcomputer scienceandelectronic engineeringrequired to developcomputer hardwareandsoftware.^[1]Computer engineering is referred to ascomputer science and engineeringor Electrical and Computer engineering at some universities

Computer engineers require training inelectronic engineering,computer science, hardware-software integration,software design, andsoftware engineering. It uses the techniques and principles of electrical engineering and computer science, and can encompass areas such asartificial intelligence (AI),robotics,computer networks,computer architectureandoperating systems. Computer engineers are involved in many hardware and software aspects ofcomputing, from the design of individualmicrocontrollers,microprocessors,personal computers, andsupercomputers, tocircuit design. This field of engineering not only focuses on how computer systems themselves work, but also on how to integrate them into the larger picture.^[2]Roboticsare one of the applications of computer engineering.

Computer engineering usually deals with areas includingwriting softwareandfirmwareforembeddedmicrocontrollers, designingVLSIchips,analogsensors,mixed signalcircuit boards, andoperating systems. Computer engineers are also suited forroboticsresearch, which relies heavily on usingdigital systemsto control and monitorelectrical systemslikemotors,communications, andsensors.

In many institutions of higher learning, computer engineering students are allowed to choose areas of in-depth study in their junior and senior years because the full breadth of knowledge used in the design and application of computers is beyond the scope of anundergraduate degree. Other institutions may requireengineering studentsto complete one or two years ofgeneral engineeringbefore declaring computer engineering as their primary focus.^[3][4][5][6]

Computer engineering began in 1939 whenJohn Vincent AtanasoffandClifford Berrybegan developing the world's first electronicdigital computerthroughphysics,mathematics, andelectrical engineering. John Vincent Atanasoff was once a physics and mathematics teacher forIowa State Universityand Clifford Berry a former graduate under electrical engineering and physics. Together, they created theAtanasoff-Berry computer, also known as the ABC which took five years to complete.^[7]While the original ABC was dismantled and discarded in the 1940s, a tribute was made to the late inventors; a replica of the ABC was made in 1997, where it took a team of researchers and engineers four years and $350,000 to build.^[8]

The modernpersonal computeremerged in the 1970s, after several breakthroughs insemiconductortechnology. These include the first workingtransistorbyWilliam Shockley,John BardeenandWalter BrattainatBell Labsin 1947,^[9]planar processbyJean Hoerni,^[10][11]themonolithic integrated circuitchip byRobert NoyceatFairchild Semiconductorin 1959,^[12]themetal–oxide–semiconductor field-effect transistor(MOSFET, or MOS transistor) byMohamed AtallaandDawon Kahngat Bell Labs in 1959,^[13][14][15]and the single-chipmicroprocessor(Intel 4004) byFederico Faggin,Marcian Hoff,Masatoshi ShimaandStanley MazoratIntelin 1971.^[16]

The first computer engineering degree program in the United States was established in 1971 atCase Western Reserve UniversityinCleveland,Ohio.^[17]As of 2015^[update], there were 250ABET-accredited computer engineering programs in the U.S.^[18]In Europe, accreditation of computer engineering schools is done by a variety of agencies as part of theEQANIEnetwork. Due to increasing job requirements for engineers who can concurrently design hardware,software, firmware, and manage all forms of computer systems used in industry, some tertiary institutions around the world offer abachelor's degreegenerally called computer engineering. Both computer engineering andelectronic engineeringprograms include analog and digital circuit design in their curriculum. As with most engineering disciplines, having a sound knowledge ofmathematicsand science is necessary for computer engineers.

Computer engineering is referred to ascomputer science and engineeringat some universities. Most entry-level computer engineering jobs require at least a bachelor's degree in computer engineering, electrical engineering or computer science. Typically one must learn an array ofmathematicssuch ascalculus,linear algebraanddifferential equations, along withcomputer science.^[19]Degrees inelectronicorelectric engineeringalso suffice due to the similarity of the two fields. Because hardware engineers commonly work with computer software systems, a strong background in computer programming is necessary. According to BLS, "a computer engineering major is similar to electrical engineering but with some computer science courses added to the curriculum".^[20]Some large firms or specialized jobs require a master's degree.

It is also important for computer engineers to keep up with rapid advances in technology. Therefore, many continue learning throughout their careers. This can be helpful, especially when it comes to learning new skills or improving existing ones. For example, as the relative cost of fixing a bug increases the further along it is in the software development cycle, there can be greater cost savings attributed to developing and testing for quality code as soon as possible in the process, particularly before release.^[21]

A person with a profession in computer engineering is called a computer engineer.

There are two major focuses in computer engineering: hardware and software.

According to theBLS, Job Outlook employment for computer hardware engineers, the expected ten-year growth from 2019 to 2029 for computer hardware engineering was an estimated 2% and a total of 71,100 jobs. ("Slower than average" in their own words when compared to other occupations)".^[22]This is a decrease from the 2014 to 2024 BLS computer hardware engineering estimate of 3% and a total of 77,700 jobs. "^[22]and is down from 7% for the 2012 to 2022 BLS estimate^[22]and is further down from 9% in the BLS 2010 to 2020 estimate.^[22]" Today, computer hardware is somehow equal^{[clarification needed]}to electronic and computer engineering (ECE) and has been divided into many subcategories; the most significant^{[citation needed]}is embedded system design.^[20]

According to the U.S.Bureau of Labor Statistics(BLS), "computer applications software engineers and computer systems software engineers are projected to be among the faster than average growing occupations" The expected ten-year growth as of 2014^[update]for computer software engineering was an estimated seventeen percent and there was a total of 1,114,000 jobs that same year.^[23]This is down from the 2012 to 2022 BLS estimate of 22% for software developers.^[24][23]And, further down from the 30% 2010 to 2020 BLS estimate.^[25]In addition, growing concerns over cybersecurity add up to put computer software engineering high above the average rate of increase for all fields. However, some of the work will be outsourced in foreign countries.^[26]Due to this, job growth will not be as fast as during the last decade, as jobs that would have gone to computer software engineers in the United States would instead go to computer software engineers in countries such as India.^[27]In addition, the BLS Job Outlook for Computer Programmers, 2014–24 has an −8% (a decline, in their words),^[27]then a Job Outlook, 2019-29 of -9% (Decline),^[28]then a 10% decline for 2021-2031^[28]and now an 11% decline for 2022-2032^[28]for those who program computers (i.e. embedded systems) who are not computer application developers.^[29][30]Furthermore, women in software fields has been declining over the years even faster than other engineering fields.^[31]

Computer engineering is generally practiced within larger product development firms, and such practice may not be subject to licensing.^[32][33]However, independent consultants who advertise computer engineering, just like any form of engineering, may be subject to state laws which restrictprofessional engineerpractice to only those who have received the appropriate License.^[34][35]TheNational Council of Examiners for Engineering and Surveying(NCEES) first offered aPrinciples and Practice of Engineering Examinationfor computer engineering^[36]in 2003.

There are many specialty areas in the field of computer engineering.

Processor design process involves choosing an instruction set and a certain execution paradigm (e.g. VLIW or RISC) and results in a microarchitecture, which might be described in e.g. VHDL or Verilog. CPU design is divided into design of the following components: datapaths (such as ALUs and pipelines), control unit: logic which controls the datapaths, memory components such as register files, caches, clock circuitry such as clock drivers, PLLs, clock distribution networks, pad transceiver circuitry, logic gate cell library which is used to implement the logic.

Computer engineers work in coding, applied cryptography, and information protection to develop new methods for protecting various information, such as digital images and music, fragmentation, copyright infringement and other forms of tampering by, for example,digital watermarking.^[37]

Those focusing on communications and wireless networks, work advancements in telecommunications systems and networks (especially wireless networks), modulation and error-control coding, and information theory. High-speednetwork design, interference suppression and modulation, design, and analysis offault-tolerant system, and storage and transmission schemes are all a part of this specialty.^[37]

This specialty focuses oncompilersandoperating systemsdesign and development. Engineers in this field develop new operating system architecture, program analysis techniques, and new techniques to assure quality. Examples of work in this field include post-link-time code transformation algorithm development and new operating system development.^[37]

Computational science and engineering is a relatively new discipline. According to the Sloan Career Cornerstone Center, individuals working in this area, "computational methods are applied to formulate and solve complex mathematical problems in engineering and the physical and the social sciences. Examples include aircraft design, the plasma processing of nanometer features on semiconductor wafers,VLSIcircuit design, radar detection systems, ion transport through biological channels, and much more".^[37]

In this specialty, engineers build integrated environments for computing, communications, andinformation access. Examples include shared-channel wireless networks,adaptive resource managementin various systems, and improving the quality of service in mobile and ATM environments. Some other examples include work on wireless network systems and fast Ethernet cluster wired systems.^[37]

Engineers working in computer systems work on research projects that allow for reliable, secure, and high-performance computer systems. Projects such as designing processors for multi-threading and parallel processing are included in this field. Other examples of work in this field include the development of new theories, algorithms, and other tools that addperformanceto computer systems.^[37]

Computer architecture includesCPU design,cache hierarchylayout,memory organization, andload balancing.

In this specialty, computer engineers focus on developingvisual sensing technologyto sense an environment, representation of an environment, and manipulation of the environment. The gathered three-dimensional information is then implemented to perform a variety of tasks. These include improved human modeling, image communication, and human-computer interfaces, as well as devices such as special-purpose cameras with versatile vision sensors.^[37]

Individuals working in this area design technology for enhancing the speed, reliability, and performance of systems. Embedded systems are found in many devices from a small FM radio to the space shuttle. According to the Sloan Cornerstone Career Center, ongoing developments in embedded systems include "automated vehicles and equipment to conduct search and rescue, automated transportation systems, and human-robot coordination to repair equipment in space."^[37]As of 2018^[update], computer embedded systems specializations includesystem-on-chipdesign, the architecture ofedge computingand theInternet of things.

This specialty of computer engineering requires adequate knowledge of electronics and electrical systems. Engineers working in this area work on enhancing the speed, reliability, and energy efficiency of next-generation very-large-scale integrated (VLSI) circuits and microsystems. An example of this specialty is work done on reducing the power consumption of VLSI algorithms and architecture.^[37]

Computer engineers in this area develop improvements in human–computer interaction, includingspeech recognitionand synthesis, medical and scientific imaging, or communications systems. Other work in this area includes computer vision development such asrecognition of human facial features.^[37]

This area integrates thequantumbehaviour of small particles such assuperposition,interferenceandentanglement, with classical computers to solve complex problems and formulate algorithms much more efficiently. Individuals focus on fields likeQuantum cryptography,physical simulationsandquantum algorithms.

An accessible avenue for obtaining information and opportunities in technology, especially for young students, is through digital platforms, enabling learning, exploration, and potential income generation at minimal cost and in regional languages, none of which would be possible without engineers.^[38]Computer engineering is important in the changes involved in industry 4.0, with engineers responsible for designing and optimizing the technology that surrounds our lives, from big data to AI. Their work not only facilitates global connections and knowledge access, but also plays a pivotal role in shaping our future, as technology continues to evolve rapidly, leading to a growing demand for skilled computer engineers.^[39]Engineering contributes to improving society by creating devices and structures impacting various aspects of our lives, from technology to infrastructure. Engineers also address challenges such as environmental protection and sustainable development, while developing medical treatments.^[40]As of 2016, the median annual wage across all BLS engineering categories was over $91,000. Some were much higher, with engineers working for petroleum companies at the top (over $128,000). Other top jobs include: Computer Hardware Engineer – $115,080, Aerospace Engineer – $109,650, Nuclear Engineer – $102,220.^[41]
