The Pentium 4 processor is Intel’s microprocessor that was introduced at 1.5GHz in November of 2000. It implements the new Intel NetBurst micro-architecture that features significantly higher clock rates and world-class performance. It includes several important new features and innovations that will allow the Intel pentium 4 processor to deliver industry-leading performance for the next several years. The Pentium 4 processor is designed to deliver performance across applications
where end users can truly appreciate and experience its performance.
For example, it allows a much better user experience in areas such as Internet audio and streaming video, image processing, video content creation, speech recognition, 3D applications and games, multi-media and multi-tasking user environments. The Pentium 4 processor enables realtime MPEG2 video encoding and near real-time MPEG4 encoding, allowing efficient video editing and video conferencing. It delivers world-class performance on 3D applications and games.
It adds 144 new 128-bit Single Instruction Multiple Data (SIMD) instructions called SSE2 (Streaming SIMD Extension 2) that improves performance for multi-media, content creation, scientific, and engineering applications. Intel NetBurst micro-architecture of the Pentium 4 processor has four main sections: the in-order front end, the out-of-order execution engine, the integer and floating-point execution units, and the memory subsystem.
The Pentium 4 processor has a 20-stage misprediction pipeline while the 6 micro-architecture has a 10-stage misprediction (This pipeline covers the cycles it takes a processor to recover from a branch that went a different direction than the early fetch hardware predicted at the beginning of the machine pipeline) pipeline. By dividing the pipeline into smaller pieces, doing less work during each pipeline stage (fewer gates of logic), the clock rate can be a lot higher. The Pentium 4 processor has a system bus with 3.2 G-bytes per second of bandwidth. This high bandwidth is a key enabler for applications that stream data from memory.
This bandwidth is achieved with a 64-bit wide bus capable of transferring data at a rate of 400MHz. It uses a source-synchronous protocol that quad-pumps the 100MHz bus to give 400 million data transfers per second. It has a split-transaction, deeply pipelined protocol to allow the memory subsystem to overlap many simultaneous requests to actually deliver high memory bandwidths in a real system. The bus protocol has a 64- byte access length. The Pentium 4 processor has 42 million transistors implemented on Intel’s 0.18u CMOS process, with six levels of aluminum interconnect.
