Intel Announces New NetBurst Micro-architecture for Pentium 4 Processor.Business Editors/Technology Writers Intel Developer Forum Intel Developer Forum (IDF), is a twice yearly gathering of technologists to discuss Intel products and products based around Intel products. The first IDF was in 1997. There is usually a Spring IDF and a Fall IDF. Fall 2000 SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--Aug. 22, 2000 Intel Corporation (company) Intel Corporation - A US microelectronics manufacturer. They produced the Intel 4004, Intel 8080, Intel 8086, Intel 80186, Intel 80286, Intel 80386, Intel 486 and Pentium microprocessor families as well as many other integrated circuits and personal computer networking today disclosed details of its new NetBurst(TM) micro-architecture, the name for the technical features contained in its upcoming Intel(R) Pentium(R) 4 processor. This new processor is scheduled to be introduced later this year. Albert Yu, senior vice president and general manager of the Intel Architecture Group, explained that the NetBurst micro-architecture is the first new desktop processor micro-architecture for Intel since the P6 micro-architecture was introduced in the Pentium(R) Pro processor in 1995. The Pentium 4 processor is initially targeted at the consumer enthusiasts and business power users. The new Pentium 4 processor is based on an advanced technology designed to maximize performance both today and in the future while keeping consumers on the cutting edge of the Internet. Intel Pentium 4 Processor Design Goals As part of the Pentium 4 design development process, Intel targeted the delivery of world class, end-user appreciable performance across both existing and emerging applications and usage models. Specific attention was focused on Internet, imaging, streaming video A one-way video transmission over a data network. It is widely used on the Web as well as company networks to play video clips and video broadcasts. Computers in home networks stream video to digital media hubs connected to a home theater. , speech, 3-D, multimedia and multi-tasking user environments. In addition, Intel set out to develop a next generation micro-architecture that would deliver both performance and frequency scalability well into the future. New NetBurst Micro-Architecture Features -- Hyper Pipelined Technology -- The Intel(R) Pentium(R) 4 processor doubles the pipeline depth to 20 stages, significantly increasing processor performance and frequency capability. -- Rapid Execution Engine -- The processor's Arithmetic Logic Units (ALUs) run at twice the core frequency, allowing it to execute certain instructions in 1/2 core clock tick One increment, or pulse, of the CPU clock. See clock speed and clock. . Integer instructions execute at twice the speed of the rest of the processor. This results in higher execution throughput and reduced latency of execution. -- 400 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. System Bus -- This advanced, split-transaction, deeply pipelined system bus delivers three times the bandwidth of the Intel(R) Pentium(R) III processor system bus. It has 128-byte lines with 64-byte accesses (32-byte lines on the previous generation). This provides a 3.2 gigabyte transfer speed between the Pentium 4 processor and the memory controller and is the highest bandwidth desktop system bus available. -- Execution Trace Cache -- This is an advanced Level 1 instruction cache that caches decoded instructions (~12K micro-ops), thus removing the decoder latency from main execution loop. This revolutionary technology delivers a much higher performance instruction cache as well as makes more efficient use of cache memory storage. In addition, the Pentium 4 processor's Level 2 Advanced 256 KB Transfer Cache delivers a 48GB/sec interface that scales with core frequency increases. Improved NetBurst Micro-Architecture Features -- Advanced Dynamic Execution -- The Pentium 4 processor has an extremely efficient out-of-order speculative execution (processor) speculative execution - A technique allows a superscalar processor to keep its functional units as busy as possible by executing instructions before it is known that they will be needed. The Intel P6 uses speculative execution. engine that keeps the execution units busy. Also new is an enhanced branch prediction In CPU instruction execution, predicting the outcome of a branch so that those instructions may be executed in parallel with the current instructions. If the CPU guesses the wrong branch, it will take extra machine cycles to go back and execute the correct one; however, on average, if the capability that keeps the processor executing to the correct program flow and reduces the mis-prediction penalty associated with deeper pipelines. -- Streaming SIMD (Single Instruction stream Multiple Data stream) A computer that performs one operation on multiple sets of data. It is typically used to add or multiply eight or more sets of numbers at the same time for multimedia encoding and rendering as well as scientific Extension 2 (SSE (1) An earlier full-screen editor in OS/2. (2) (Streaming SIMD Extensions) A series of additional instructions built into Pentium CPU chips for improved multimedia performance by performing mathematical operations on multiple sets of data at the 2) -- SSE2 extends MMX (MultiMedia EXtensions) A set of 57 additional instructions built into the Pentium MMX chip for improved multimedia and modem performance by performing mathematical operations on multiple sets of data at the same time (see SIMD). (TM) and SSE technology with the addition of 144 new instructions, including 128-bit SIMD integer arithmetic Arithmetic without fractions. A computer performing integer arithmetic ignores any fractions that are derived. For example, 8 divided by 3 would yield the whole number 2. See integer. and 128-bit SIMD double precision floating point instructions that delivers performance increases across a broad range of applications. About IDF (Intermediate Distribution Frame) A wiring rack located between the MDF (main distribution frame) and the intended end user devices (telephones, routers, PCs, etc.). Cables run from the outside world to the MDF and then to the IDFs. See MDF and wiring rack. The Intel Developer Forum Conference is Intel's premier technical forum comprising nearly 250 sessions and hands-on labs and more than 100 demonstrations of cutting-edge products and technologies. IDF attracts thousands of hardware and software developers worldwide. Now in its third year, the semi-annual conference provides hardware OEMs (original equipment manufacturers), IHVs (independent hardware vendors), and ISVs (independent software vendors) with in-depth information on Intel technologies and initiatives. More information on the Intel Developer Forum can be found at http://developer.intel.com/idf. Updated information is available between Intel Developer Forums by subscribing to the Intel Developer Update Magazine at http://developer.intel.com/update/. Intel, the world's largest chip maker, is also a leading manufacturer of computer, networking and communications products. Additional information about Intel is available at www.intel.com/pressroom.
