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.

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.
