CPU – central processing unit:
• CISC, RISC architecture
• number of bits in one cycle 32 or 64
• frequency clocking in MHz
Processor History:
Intel 4004 – 8-bit, 0. 74 MHz frequency, 2250 transistors, 1971.
Intel 8008 – 8 bits, 3500 transistors, 1972
Intel 8080 – 2 MHz, 4500 transistors, 1975r.
Processor Construction:
• stress and synchronization system
• arrhythmometer
• registers
• cache
• mathematical coprocessor
• rails connecting elements of the processor
Basic Registers:
• order counter
• order register
• battery
• register of markers
Functional Extensions:
• 57 MMX instructions
• SIMD type
• 21 new instructions introduced by AMD, SMID-FP type supports graphics: 3DNOW, 64 bit register
• Intel introduced SSE, variable-comma instructions on 128 dedicated registers, promotes optimization of program code
Raiting points – used by AMD as a performance indicator.
Multi-core:
Thanks to miniaturization and the idea of placing multiple cores in one processor, we are able to significantly increase the computing power of one device. Currently there are 16 cores! Development of electronics and data control software the ability to allocate resources and processes to individual core which significantly increases the efficiency of work, especially in server applications.
Intel Atom:
Personally, I consider it a mistake among the processors. They have only one core, but a virtualization that makes it seem to have two cores. Unfortunately, this is an average processor suitable for any use. Interesting thing from my own experience is that compared to the very old 2. 6 GHz Celeron my Intel Atom processes the graphic file in Gimp 2x longer and is much younger technology.
Intel Core:
A type of multi-core and very powerful processors.
Intel Xeon:
Server processors, very seems and having a large amount of memory L.
