Study Notes
Microprocessor Overview
- A microprocessor incorporates a computer's central processing unit (CPU) onto a single integrated circuit (IC).
- It's a programmable device, accepting digital input, processing it according to stored instructions, and providing output.
- It operates using the binary numeral system.
- Low-cost microprocessors have transformed modern society, impacting computation, text editing, multimedia display, and internet communication.
- Microprocessors are vital components of embedded systems for control and process control in various applications.
History of Microprocessors
- Early computer processors (1960s) were constructed from multiple small/medium-scale integrated circuits (ICs).
- The Apollo Guidance Computer, a custom processor used in NASA Apollo missions, was built using a gate array of three-input NOR gates.
- The integration of the entire CPU onto a single chip drastically reduced processing costs and increased reliability.
- The early 1970s saw the emergence of the first microprocessors for electronic calculators using binary-coded decimal (BCD) arithmetic.
- The Intel 4004, introduced in 1971, is considered the first commercially available microprocessor.
Embedded Applications
- Microprocessors are common in a wide array of traditionally non-computerized items (appliances, car keys, tools, instruments, toys, etc.).
- They are crucial in controlling emissions in automobiles, allowing optimized performance under varying operating conditions.
- Microprocessor systems are often more efficient and less costly than comparable analog control systems.
Advantages of Microprocessor Control Systems
- Microprocessor control programs can be customized for various product needs, permitting easy upgrades and minimal design changes.
- It offers control strategies impractical with electromechanical systems in applications like vehicle engine control systems.
- The programmable nature allows for easy adaptation to changing conditions or needs of the product.

- Intel 4004, Garrett AiResearch's Central Air Data Computer (CADC), and Texas Instruments (TI) TMS 1000 were among the first microprocessors to be developed simultaneously.
- The Intel 4004 was introduced in 1971 and cost $60.
8-bit designs
- Intel 8008 (1972), first 8-bit microprocessor, was built from separate design project and not extension of 4004 design
- Different teams involved in other microprocessors' designs
- Multiple companies developed and supplied microprocessor designs
Later Microprocessor Developments
- Continued advancements and developments in microprocessor design led to the creation of more powerful and efficient designs.
- Advancements were made in many aspects of the microprocessor, including both the hardware and software.
Multicore Designs
- Multi-core processors, containing several microprocessor cores on a single chip, are a common means of improving performance.
- The physical closeness of cores allows for more efficient communication, increasing overall system performance.
- Early 2000s saw the rise of dual-core processors, and increased core counts to 12 and 16 became common in professional and enterprise markets.
32-bit designs
- The 68000, a 32-bit design from Motorola, had significant market adoption.
- The 68000 family, with significant market success, was used in a wide variety of products.
- Other 32-bit microprocessor designs, such as the iAPX 432 and the Bell Labs BELLMAC-32A, were also developed.
64-bit designs
- Following the development of 32-bit designs, the introduction of 64-bit microprocessors was significant.
- AMD 64 and Intel 64 made 64-bit processors compatible with their 32-bit counterparts.
- 64-bit processors gained importance due to improved processing capacity and more capability.
Other Notable Microprocessors
- Specific processors like the RCA 1802 (COSMAC) were designed for use in spaceflight and were particularly known for their low power consumption and radiation-hardening capabilities.
- WDC CMOS 65816 was introduced as a 16 bit upgrade of WDC CMOS 65C02.
- National Semiconductor IMP-16 and its 8-bit version IMP-8 were among the first multichip 16-bit microprocessors and were significant developments in their time.
