“The greatest growling engine of change - technology and what’s fueling it is the majestic human mind!”
Back in 1947, when the transistor was invented, who would have ever thought that later after certain advancements, 2300 transistors could possibly be used in small single-integrated circuits, the first microprocessors as small as a little fingernail ( delivering the same computing power as the first electronic computer built in 1946, which filled an entire room ).
What opened the door for the first microprocessors, then, was the application of MOS integrated circuits to computing. In the early 1970s, the introduction of large scale integration (LSI)-which made it possible to embed thousands of transistors, diodes, and resistors onto a Silicon chip led to the development of the microprocessor. Designers were working to integrate the CPU functions of a computer onto a handful of such chips, called microprocessor unit (MPU) chipsets.
"If you are going to put a few thousand dollars worth of memory [in a computer], wouldn't it make more sense to spend $500 for a processor built out of small- or medium- scale electronics and have 100 times the performance,” said Ted Hoff who together with the co-inventors Mazor and Faggin at Intel Corporation came up with the idea of the design for the microprocessor.
The first microprocessor was the Intel 4004, released in 1971. The 4004 was the first such logic circuit integrated into one chip using the MOS (metal–oxide–semiconductor) silicon gate technology (SGT).
Let's begin with the history behind this first-ever commercially produced microprocessor. There was a time when computers were still rare and calculators were commonly used. In fact, it was a calculator project that turned into a milestone in the history of computing technology.
Busicom, a Japanese calculator company, had designed its own special-purpose LSI chipset to be used in a 141-PF calculator. But it's design used serial read-write memories which made it too complex since these serial memories required more components, and would consequently use about 40 pins ( a packaging standard different from Intel's 16-pin standard). In 1969 Busicom approached Intel Corporation to develop its design for the custom chips for production.
So, Intel proposed to develop a new design that could be produced with standard 16-pin DIP packaging and hence would have a reduced instruction set. This newly proposed design included a set of four chips known as the MCS-4 which included: the central processing unit (CPU) chip - 4004 chip, along with a supporting ROM chip, a RAM chip, and shift register chips for the input/output port.
When Busicom gave exclusive rights to Intel, it began marketing the chip to other manufacturers in 1971.
The 4004 a four-bit processor had a major limitation that it was capable of only 24, or 16, distinct combinations, or “words.” To distinguish the 26 letters of the alphabet and up to six punctuation symbols, the computer had to combine two four-bit words.
The 4004, was followed by the first-ever 8-bit microprocessor, the 3,500 transistor 8008 (and the 4040, a revised and improved 4004).
The 4004 marked the beginning of Intel’s rise to global prominence in the processor industry. Intel’s first microprocessor; its invention, introduction, and lasting influence had a great turn around in the advancement of computing technology and has now influenced the whole modern computer world.
Now answer this:
"What was the early numbering scheme used by Intel for its integrated circuits before the Intel 4004 was named so, breaking away from the Intel's early numbering scheme? "

if you are saying Intel 4004 is first microprocessor then how numbering is done before?
ReplyDeletebtw good article.
Thank You. We hope for your reviews and suggestions ahead as well.
DeleteNow to answer your question :Intel was an early developer of SRAM and DRAM memory chips and it used a specific numbering scheme for these but as per new naming convention the chips of the MCS-4 family were named as 4001,4002,4003,4004.
