They founded the well-known company Fairchild Semiconductors in Mountain View, California, in Gordon Moore was the president and Robert Noyce the chief in design and development. Most of the basics of modern Planar Process Technology has been proposed and implemented in this company. The Beginnings

This prediction became true over decades and is the most cited statement about the exponential growth of transistor count in integrated chips. It is well known as Moore-curve or Moore’s Law which shows the doubling of transistor count every 18 month The Beginnings

The main motivation for founding Intel was the replacement of the bulky and low capacity ferrit-core-memories by integrated memories on the basis of silicon. Intel became soon one of the leading companies for mass production of integrated memories. The responsible engineer scientist for the development of DRAMs was Andy Grove. Foundation of Intel

The project deals with the design of integrated chips for a calculator specified by Busycom. Instead of the development of several special chips, a new concept was proposed by Ted Hoff and Federico Faggin, both designer of Intel. The concept of microprocessor

The instruction set was comparable to the ISA of a DEC minicomputer at that time. A chip set of 4 chips was designed (4001, 4002, 4003, 4004) where the complete instruction set microarchitecture was integrated on one chip (4004) The concept of the microprocessor was born.

The high reputation of Intel in the group of microprocessor manufactures was founded by the series 4004, 8008, 8080 followed by 80286, and up to the well known PentiumX series. Due to the high success in microprocessor mass production Intel decided to refuse from the memory market and to concentrate in the microprocessor design.

These decades are characterized by assembler programming. Therefore the programmer should be supported with complex instructions. A high level functionality on the level of the Instruction Set Architecture (ISA) was intended to bridge the semantic gap between machine instructions and high level language. The basic technology was microprogramming. Complex machine instructions are decoded by microcode. Prominent representation for this class of CISC processors is the x86 ISA.

Hier wird Wissen Wirklichkeit Computer Architecture – Part 2 – page 17 of 17 – Prof. Dr. Uwe Brinkschulte, Prof. Dr. Klaus Waldschmidt CISC / RISC paradigm In the beginning of the eighties, a new concept, the RISC paradigm (Reduced Instruction set) was developed. By having simple instructions, these could be executed more quickly. The main idea was, even so programs growing larger the overall execution time could be reduced by quicker execution. This idea came true! The RISC idea mainly triggered and influenced modern processor microarchitecture All today’s high performance microprocessor consist of an internal RISC kernel Some of them (e.g. Intel Pentium) hide this RISC kernel by a CISC like ISA layer (e.g. for compatibility reasons)
