8575A N/B Maintenance
Supported by the SiS650 chipset Fully compatible with existing Intel Architecture-based software Internet Streaming SIMD Extensions 2 Intel® MMXTM media enhancement technology Memory cache ability up to 4 GB of addressable memory space and system memory scalability up to 64GB of physical memory Support for uni-processor designs Based upon Intel's 0.18 micron manufacturing process Intel Pentium 4 Processor Product Feature Highlights The Intel NetBurst micro-architecture delivers a number of new and innovative features including Hyper Pipelined Technology, 400 MHz System Bus, Execution Trace Cache, and Rapid Execution Engine as well as a number of enhanced features Advanced Transfer Cache, Advanced Dynamic Execution, Enhanced Floatingpoint and Multi-media Unit, and Streaming SIMD Extensions 2. Many of these new innovations and advances were made possible with improvements in processor technology, process technology, and circuit design that could not previously be implemented in high-volume, manufacturable solutions. The features and resulting benefits of the new micro-architecture are defined below.

8

8575A N/B Maintenance
Hyper Pipelined Technology: The hyper-pipelined technology of the NetBurst micro-architecture doubles the pipeline depth compared to the P6 micro-architecture used on today's Pentium III processors. One of the key pipelines, the branch prediction/ recovery pipeline, is implemented in 20 stages in the NetBurst micro-architecture, compared to 10 stages in the P6 micro-architecture. This technology significantly increases the performance, frequency, and scalability of the processor. 400 MHZ System Bus: The Pentium4 processor supports Intel's highest performance desktop system bus by delivering 3.2 GB of data per second into and out of the processor. This is accomplished through a physical signaling scheme of quad pumping the data transfers over a 100-MHz clocked system bus and a buffering scheme allowing for sustained 400-MHz data transfers. This compares to 1.06 GB/s delivered on the Pentium III processor's 133-MHz system bus. Level 1 Execution Trace Cache: In addition to the 8KB data cache, the Pentium 4 processor includes an Execution Trace Cache that stores up to 12K decoded micro-ops in the order of program execution. This increases performance by removing the decoder from the main execution loop and makes more efficient usage of the cache storage space since instructions that are branched around are not stored. The result is a means to deliver a high volume of instructions to the processor's execution units and a reduction in the overall time required to recover from branches that have been mis-predicted.

9

8575A N/B Maintenance
Rapid Execution Engine: Two Arithmetic Logic Units (ALUs) on the Pentium 4 processor are clocked at twice the core processor frequency. This allows basic integer instructions such as Add, Subtract, Logical AND, Logical OR, etc. to execute in half a clock cycle. For example, the Rapid Execution Engine on a 1.50 GHz Pentium 4 processor runs at 3 GHz. 256KB, Level 2 Advanced Transfer Cache: The Level 2 Advanced Transfer Cache (ATC) is 256KB in size and delivers a much higher data throughput channel between the Level 2 cache and the processor core. The Advanced Transfer Cache consists of a 256bit (32-byte) interface that transfers data on each core clock. As a result, the Pentium 4 processor 1.50 GHz can deliver a data transfer rate of 48 GB/s. This compares to a transfer rate of 16 GB/s on the Pentium III processor at 1 GHz. Features of the ATC include: Non-Blocking, full speed, on-die Level 2 cache 8-way set associativity 256-bit data bus to the level 2 cache Data clocked into and out of the cache every clock cycle Advanced Dynamic Execution: The Advanced Dynamic Execution engine is a very deep, out-of-order speculative execution engine that keeps the execution units executing instructions. The Pentium 4 processor can also view 126 instructions in flight and handle up to 48 loads and 24 stores in the pipeline. It also includes an enhanced branch prediction algorithm that has the net effect of reducing the number of branch mis-predictions by about 33% over the P6 generation processor's branch prediction capability. It does this by implementing a 4KB branch target buffer that stores more detail on the history of past branches, as well as by implementing a more advanced branch prediction algorithm.
10

8575A N/B Maintenance
Enhanced Floating-Point and Multimedia Unit: The Pentium 4 processor expands the floating-point registers to a full 128-bit and adds an additional register for data movement which improves performance on both floating-point and multimedia applications. Internet Streaming SIMD Extensions 2 (SSE2): With the introduction of SSE2, the NetBurst micro-architecture now extends the SIMD capabilities that MMX technology and SSE technology delivered by adding 144 new instructions. These instructions include 128-bit SIMD integer arithmetic and 128-bit SIMD double-precision floating-point operations. These new instructions reduce the overall number of instructions required to execute a particular program task and as a result can contribute to an overall performance increase. They accelerate a broad range of applications, including video, speech, and image, photo processing, encryption, financial, engineering and scientific applications. Features Used for Test and Performance / Thermal Monitoring: Built-in Self Test (BIST) provides single stuck-at fault coverage of the micro-code and large logic arrays, as well as testing of the instruction cache, data cache, Translation Lookaside Buffers (TLBs), and ROMs. IEEE 1149.1 Standard Test Access Port and Boundary Scan mechanism enables testing of the Pentium 4 processor and system connections through a standard interface. Internal performance counters can be used for performance monitoring and event counting. Includes a new Thermal Monitor feature that allows motherboards to be cost effectively designed to expected application power usages rather than theoretical maximums.

17

8575A N/B Maintenance
Two separate buses, Host-t-GUI in the width of 64 bit, and GUI-t-Memory Controller in the width of 128 bit are devised to ensure concurrency of Host-t-GUI streaming, and GUI-t-MC streaming. In PC133, or DDR266 memory subsystem, the 128 bit GUI-t-MC bus will attain the AGP4X or AGP 8X equivalent texture transfer rate, respectively. The Memory Controller mainly comprises the Memory Arbiter, the M-data/MCommand Queues, and the Memory Interface. The Memory Arbiter arbitrates a plenty of memory access requests from the GUI or AGP controller, Host Controller, and I/O bus masters based on a default optimized priority list with the capability of dynamically prioritizing the I/O bus master requests in a bid to offering privileged service to 1) the isochronous downstream transfer to guarantee the min. latency & timely delivery, or 2) the PCI master upstream transfer to curb the latency within the maximum tolerant period of 10us. Prior to the memory access requests pushed into the M-data queue, any command compliant to the paging mechanism is generated and pushed into the M-CMD queue. The M-data/M-CMD Queues further orders and forwards these queuing requests to the Memory Interface in an effort to utilizing the memory bandwidth to its utmost by scheduling the command requests in the background when the data requests streamlines in the foreground.

1.2.5.1 Single-Slot PC Card Power Interface Switch: TPS2211A
The TPS2211A PC Card power-interface switch provides an integrated power-management solution for a single PC Card. All of the discrete power MOSFETs, a logic section, current limiting, and thermal protection for PC Card control are combined on a single integrated circuit, using the Texas Instruments LinBiCMOSTM process. The circuit allows the distribution of 3.3-V, 5-V, and/or 12-V card power, and is compatible with many PCMCIA controllers. The current-limiting feature eliminates the need for fuses, which reduces component count and improves reliability. Current-limit reporting can help the user isolate a system fault to the PC Card. The TPS2211A features a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5 V. Bias power can be derived from either the 3.3-V or 5-V inputs. This facilitates low-power system designs such as sleep mode and pager mode where only 3.3 V is available. End equipment for the TPS2211A includes notebook computers, desktop computers, personal digital assistants (PDAs), digital cameras, and bar-code scanners.

39

8575A N/B Maintenance
The ICS1893 incorporates digital signal processing (DSP) in its Physical Medium Dependent (PMD) sublayer. As a result, it can transmit and receive data on unshielded twisted-pair (UTP) category 5 cables with attenuation in excess of 24 dB at 100 MHz. With this ICS-patented technology, the ICS1893 can virtually eliminate errors from killer packets. The ICS1893 provides a Serial Management Interface for exchanging command and status information with a Station Management (STA) entity. The ICS1893 Media Dependent Interface (MDI) can be configured to provide either half- or full-duplex operation at data rates of 10 MHz or 100 MHz. The MDI configuration can be established manually (with input pins or control register settings) or automatically (using the Auto-Negotiation features). When the ICS1893 Auto-Negotiation sublayer is enabled, it exchanges technology capability data with its remote link partner and automatically selects the highest-performance operating mode they have in common. Features Supports category 5 cables with attenuation in excess of 24 dB at 100 MHz across a temperature range from -5 to +85 C DSP-based baseline wander correction to virtually eliminate killer packets across temperature range from -5 to +85 C Low-power, 0.35-micron CMOS (typically 400 mW) Single 3.3-V power supply
