A Dual Core Processor Has Two Cores (Essentially, Two Cpus on One Chip)
Faculty of Engineering & Information Technology Al-Azhar University-Gaza Dr. Mohammad Aqel Microprocessors and Interfacing (ITCC 3301) Homework (1) Intel Core is a brand name used for various mid-range to high-end consumer and business microprocessors made by Intel. In general, processors sold as Core are more powerful variants of the same processors marketed as entry-level Celeron and Pentium. Similarly, identical or more capable versions of Core processors are also sold as Xeon processors for the server market. The current lineup of Core processors includes the latest Intel Core i7, Intel Core i5 and Intel Core i3, and the older Intel Core 2 Solo, Intel Core 2 Duo, Intel Core 2 Quad, and Intel Core 2 Extreme lines. 1- The original Core brand refers to Intel's 32-bit dual-core x86 CPUs. 2- Unlike the Intel Core, Intel Core 2 is a 64-bit processor, supporting Intel 64. The Core brand comprised two branches: the Duo (dual-core) and Solo (Duo with one disabled core). A dual core processor has two cores (essentially, two CPUs on one die (piece) silicon chip (IC)). Core2Duo is a specific dual-core processor design. Thus, all Core2Duo CPUs are dual-core CPUs, but not all Intel dual-core CPUs are Core2Duo designs. Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. -

Microprocessors (0630371) Fall 2010/2011 – Lecture Notes # 1 The Intel Microprocessors: Architecture, Programming and Interfacing Introduction to the Microprocessor and computer Outline of the Lecture Evolution of programming languages. Microcomputer Architecture. Instruction Execution Cycle. Evolution of programming languages: Machine language - the programmer had to remember the machine codes for various operations, and had to remember the locations of the data in the main memory like: 0101 0011 0111… Assembly Language - an instruction is an easy –to- remember form called a mnemonic code . Example: Assembly Language Machine Language Load 100100 ADD 100101 SUB 100011 We need a program called an assembler that translates the assembly language instructions into machine language. High-level languages Fortran, Cobol, Pascal, C++, C# and java. We need a compiler to translate instructions written in high-level languages into machine code.

An arithmetic and logic unit and, indeed, all electronic components in the computer are based on the use of simple digital logic devices that can store binary digits and perform simple Boolean logic operations. Data are presented to the ALU in registers. These registers are temporary storage locations within the CPU that are connected by signal paths of the ALU. -
HOW FAST? the Current Intel® Core™ Processor Has 43,000,000% More Transistors Than the 4004 Processor
40yrs of Intel® microprocessor innovation Following Moore’s Law the whole way Intel co-founder Gordon Moore once made a famous prediction that transistor The world’s first microprocessor count for computer chips would —the Intel® 4004—was “born” in 1971, double every two years. 10 years before the first PC came along. Using Moore’s Law as a guiding principle, Intel has provided ever-increasing functionality, performance and energy efficiency to its products. Just think: What if the world had followed this golden rule the last 40 years? HOW FAST? The current Intel® Core™ processor has 43,000,000% more transistors than the 4004 processor. If a village with a 1971 population of 100 had grown as quickly, it would now be by far the largest city in the world. War and Peace? Wait a second. The 4004 processor executed 92,000 instructions per second, while today’s Intel® Core™ i7 processor can run 92 billion. If your typing had accelerated at that rate, you’d be able to type Tolstoy’s classic in just over 1 second. 0101010101010101… You would need 25,000 years to turn a light switch on and off 1.5 trillion times, but today’s processors can do that in less than a second. A PENNY SAVED… When released in 1981, the first well- equipped IBM PC cost about $11,250 in inflation-adjusted 2011 dollars. Today, much more powerful PCs are available in the $500 range (or even less). Fly me to the moon If space travel had come down in price as much as transistors have since 1971, the Apollo 11 mission, which cost around $355 million in 1969, would cost about as much as a latte. -
Computer Architecture Out-Of-Order Execution
Computer Architecture Out-of-order Execution By Yoav Etsion With acknowledgement to Dan Tsafrir, Avi Mendelson, Lihu Rappoport, and Adi Yoaz 1 Computer Architecture 2013– Out-of-Order Execution The need for speed: Superscalar • Remember our goal: minimize CPU Time CPU Time = duration of clock cycle × CPI × IC • So far we have learned that in order to Minimize clock cycle ⇒ add more pipe stages Minimize CPI ⇒ utilize pipeline Minimize IC ⇒ change/improve the architecture • Why not make the pipeline deeper and deeper? Beyond some point, adding more pipe stages doesn’t help, because Control/data hazards increase, and become costlier • (Recall that in a pipelined CPU, CPI=1 only w/o hazards) • So what can we do next? Reduce the CPI by utilizing ILP (instruction level parallelism) We will need to duplicate HW for this purpose… 2 Computer Architecture 2013– Out-of-Order Execution A simple superscalar CPU • Duplicates the pipeline to accommodate ILP (IPC > 1) ILP=instruction-level parallelism • Note that duplicating HW in just one pipe stage doesn’t help e.g., when having 2 ALUs, the bottleneck moves to other stages IF ID EXE MEM WB • Conclusion: Getting IPC > 1 requires to fetch/decode/exe/retire >1 instruction per clock: IF ID EXE MEM WB 3 Computer Architecture 2013– Out-of-Order Execution Example: Pentium Processor • Pentium fetches & decodes 2 instructions per cycle • Before register file read, decide on pairing Can the two instructions be executed in parallel? (yes/no) u-pipe IF ID v-pipe • Pairing decision is based… On data -
CISC Processor - Intel X86
Architecture of Computers and Parallel Systems Part 4: Intel x86 History Ing. Petr Olivka [email protected] Department of Computer Science FEI VSB-TUO Architecture of Computers and Parallel Systems Part 4: Intel x86 History Ing. Petr Olivka [email protected] Department of Computer Science FEI VSB-TUO Architecture of Computers and Parallel Systems Part 4: Intel x86 History Ing. Petr Olivka [email protected] Department of Computer Science FEI VSB-TUO CISC Processor - Intel x86 This chapter will introduce the CISC processors evolution. We will try to illustrate the history on one typical processor, because the comparison of multiple processors simultaneously would not be clear for readers. But the selection of one typical processor is complicated due to a variety of products and manufactures in the past 30 years. We have decided to describe in this presentation one of the best- known and longest mass-produced processors in existence. We definitely do not want to say that it is the best technology or that these are processors with the highest performance! The Intel x86 processors are the selected product line. Intel 8080 (Year-Technology-Transistors-Frequency-Data bus-Address Bus) Y: 1974 T: NMOS 6μm Tr: 6000 F: 2MHz D: 8b A: 16b This 8 bit processor is not directly the first member of x86 series, but it can not be skipped. It is one of the first commercially successful microprocessors. This microprocessor became the basis for a number of the first single-board computers and its instruction set inspired other manufacturers to develop 8-bit processors.
