It is difficult to get an exact year on a series of processors since the first computers were very unique and thus there was no precise term of “processor” in the computer. Thus it was difficult to get the software to be consistent from one computer to another because of the varied architecture.
In the early 1950s, it was mostly to talk about how a computer is best served. Some of the fundamental bases of processors were developed during this decade. Among index-registers “,” return-address savinginstruction “,” Immediate operand “and” detection of invaild operations “. All these fundamental bases were developed under different projects at the Mark 1, UNIVAC I, IBM 704 and IBM 650th
A completely new architecture, namely the Von Neuman architecture came in 1952. It was designed for the processor’s data would be stored in a single storage space. It is a place where the programmed information is stored and can be read or written, with another word, RAM (Random-Access Memmory). It was a big difference between computers and ENIAC computers Neuman technology as ENIAC had saved programs on hard drives, which then had to steer through the switch to transfer the data to the processor unit instead of directly coupled to the processor.
Von Neumann architecture was named after the mathematician John Von Neumann, who was also active in the ENIAC project and thus came the idea of the individual mind.It was not until 1952 that the IAS machine, the first computer with Neumann architecture was created. The architecture has been the basis for the processor design and the principle is also used today, but much more complex.
In the early 1960s, began software easier to install because the processors became more similar, and they began a new computer system, System/360, which simplified installation of the software and it was launched in 1964.
In 1971 it launched the Intel microprocessor, Intel 4004, which was the first microprocessor. Intel designed the chip for the company Busicom for use in calculators.The following year it introduced the Intel sequel Intel 8008 with a different architecture. It is an ancestor to the current model Intel Core 2 and have some values taken from 8008 but the codes are different.
During the mid-1970s, it became more common with integrated processors in computers. The great boom was the result of the reduced price of transistors.
Intel was commissioned to develop the 8008 United States government to control the missile in the form of robots. The new innovation of the microprocessor was named 8080th
In the early 1980s, so did IBM a research on how the processor’s capacity was used and concluded that the computer language could be simplified, thereby increasing computer performance. Meanwhile, developed the processor capacity and therefore could figure out basic operations in relation to the used memory.
In the late 1980s they began to use a new data management techniques for processors.Instruction pipelining and it made it possible for a processor could perform multiple operations simultaneously and also taking on new operations in the current.
The year after the technology put forward as did a similar idea, superscalar that would let the processor work in parallel with operations instead of working with all on a single instruction.
A major innovation in the superscalar technology occurred in the early 1990s when they came on the coordination of a multi-ALU machine could be installed in the processor’s compiler (computer program from a program text written in a high level language like C or Delphi). This type of computer known as VLIW (Very Long Instruction Word) machine.
In 2001, Intel released its first 64-bit processor chip, the Itanium. It was based on the Explicitly Parallel Instruction design Computing (EPIC), which would work well with VLIW. It worked relatively well, given that the VLIW technology encountered problems during its development. Itanium first versions were also compatible with earlier 32-bit application (x86).
In the current situation so used multi-core processors. This means that a processor has up to four cores of a single chip. Cores are connected to each other via the L2 or L3 cache. Cores share on all other parts of the chip.
It is primarily Intel and AMD are battling for market share in the current situation but the first 2-core processor made by IBM and called POWER4 2001 but was not very successful. However, AMD’s two-core processor Althon 64 X2 and the corresponding Intel, Intel Core 2 Duo. The two-core processor market came on the market for private purposes 2006th The four-core processors arrived in the first quarter of 2008 and to maintain a high standard even today. It has published the six-core processors is coming in the first quarter of 2010 from Intel named Gulftown12.
