A microprocessor control program embedded software can be easily tailored to different needs of a product line, allowing upgrades in performance with minimal redesign of the product.

Different features can be implemented in different models of a product line at negligible production cost. Microprocessor control of a system can provide control strategies that would be impractical to implement using electromechanical controls or purpose-built electronic controls.

For example, an engine control system in an automobile can adjust ignition timing based on engine speed, load on the engine, ambient temperature, and any observed tendency for knocking—allowing an automobile to operate on a range of fuel grades.

History[ edit ] The advent of low-cost computers on integrated circuits has transformed modern society. General-purpose microprocessors in personal computers are used for computation, text editing, multimedia display , and communication over the Internet.

Many more microprocessors are part of embedded systems , providing digital control over myriad objects from appliances to automobiles to cellular phones and industrial process control. The first use of the term "microprocessor" is attributed to Viatron Computer Systems [5] describing the custom integrated circuit used in their System 21 small computer system announced in By the late s, designers were striving to integrate the central processing unit CPU functions of a computer onto a handful of very-large-scale integration metal-oxide semiconductor chips, called microprocessor unit MPU chipsets.

Building on an earlier Busicom design from , Intel introduced the first commercial microprocessor, the 4-bit Intel , in , followed by its 8-bit microprocessor in AL-1, an 8-bit CPU slice that was expandable to bits.

Advanced Microprocessors and Peripherals.

The first microprocessors emerged in the early s and were used for electronic calculators , using binary-coded decimal BCD arithmetic on 4-bit words. Other embedded uses of 4-bit and 8-bit microprocessors, such as terminals , printers , various kinds of automation etc. Affordable 8-bit microprocessors with bit addressing also led to the first general-purpose microcomputers from the mids on. Since the early s, the increase in capacity of microprocessors has followed Moore's law ; this originally suggested that the number of components that can be fitted onto a chip doubles every year.

With present technology, it is actually every two years, [6] and as a result Moore later changed the period to two years. This section relies too much on references to primary sources. Please improve this section by adding secondary or tertiary sources.

March Further information: Central Air Data Computer In , Garrett AiResearch who employed designers Ray Holt and Steve Geller was invited to produce a digital computer to compete with electromechanical systems then under development for the main flight control computer in the US Navy 's new F Tomcat fighter. The design was significantly approximately 20 times smaller and much more reliable than the mechanical systems it competed against, and was used in all of the early Tomcat models.

This system contained "a bit, pipelined , parallel multi-microprocessor ". The Navy refused to allow publication of the design until Ray Holt's autobiographical story of this design and development is presented in the book: The Accidental Engineer.

From its inception, it was shrouded in secrecy until when at Holt's request, the US Navy allowed the documents into the public domain. Since then people[ who? Holt has stated that no one has compared this microprocessor with those that came later.

Microprocessor Design

Its design indicates a major advance over Intel, and two year earlier. It actually worked and was flying in the F when the Intel was announced. It indicates that today's industry theme of converging DSP - microcontroller architectures was started in The layout for the four layers of the PMOS process was hand drawn at x scale on mylar film, a significant task at the time given the complexity of the chip.

Pico was a spinout by five GI design engineers whose vision was to create single chip calculator ICs. They had significant previous design experience on multiple calculator chipsets with both GI and Marconi-Elliott. Calculators were becoming the largest single market for semiconductors so Pico and GI went on to have significant success in this burgeoning market.

Busicom's original design called for a programmable chip set consisting of seven different chips. Three of the chips were to make a special-purpose CPU with its program stored in ROM and its data stored in shift register read-write memory. Ted Hoff , the Intel engineer assigned to evaluate the project, believed the Busicom design could be simplified by using dynamic RAM storage for data, rather than shift register memory, and a more traditional general-purpose CPU architecture.

Although not a chip designer, he felt the CPU could be integrated into a single chip, but as he lacked the technical know-how the idea remained just a wish for the time being. First microprocessor by Intel, the Explain with Example. Explain with their advantage and disadvantage? Ques 2. Attempt any two of the following.

Your views are always welcomed for the further improvement of this post.The copy will therefore continue from where it left off when the interrupt service routine returns control. This CPU cache has the advantage of faster access than off-chip memory and increases the processing speed of the system for many applications.
