The Intel� Pentium� III processor, Intel�s most advanced, most powerful processor, integrates the P6 Dynamic Execution microarchitecture, Dual Independent Bus (DIB) Architecture, a multi-transaction system bus, Intel� MMX� media enhancement technology and the Intel Processor Serial Number. In addition, the Intel Pentium III processor offers Internet Streaming SIMD Extensions, 70 new instructions enabling advanced imaging, 3D, streaming audio and video, and speech recognition for an enhanced Internet experience. Versions also include an Advanced Transfer Cache and Advanced System Buffering to meet the higher data bandwidth requirements of today�s environments. With the power of the next generation of the Internet, Pentium III processors are targeted for mainstream consumer and business users as well as for enthusiast/professional/performance users. The Pentium III processor also meets the needs of entry-level workstations and servers. The Intel Pentium III processor family now includes versions up to 1.0 GHz (1000 MHz) for desktop PCs, as well as entry-level workstations and servers. All are binary compatible with previous generation Intel Architecture processors. Pentium III processors are also available in two different package options: Single Edge Contact Cartridge 2 (S.E.C.C.2) and Flip-Chip Pin Grid Array (FC-PGA). The FC-PGA package is designed for the new breed of sleek, high performance, small form factor PCs. Specifications: The Pentium� III Processor is available at speeds ranging from 450 MHz to 1.0 GHz (1000 MHz) Versions available with either a 133 MHz or a 100 MHz system bus that are designed to support the Intel� 840, 820, 810e, 440GX and 440BX chipsets. Versions that incorporate 256 KB Advanced Transfer Cache (on-die, full-speed level 2 (L2) cache with Error Correcting Code (ECC) or versions that incorporate a discrete, half-speed, 512 KB in package L2 cache with ECC. 32 KB (16 KB/16 KB) non-blocking, level 1 (L1) cache. P6 Dynamic Execution microarchitecture including multiple branch prediction, data flow analysis and speculative execution. Internet Streaming SIMD Extensions, consisting of 70 new instructions that enable advanced imaging, 3D, streaming audio and video, speech recognition and an enhanced Internet experience. Intel� MMX� media enhancement technology. Dual Independent Bus (DIB) architecture increases bandwidth and performance over single-bus processors. Memory cacheability up to 4 GB of addressable memory space and system memory scalability up to 64 GB of physical memory. Both dual-processor capable and uni-processor only versions. Data integrity and reliability features such as Error Correction Code, Fault Analysis and Recovery for both system and L2 cache buses. Intel� processor serial number, designed to improve asset management, platform identification and information management capabilities. Versions based upon Intel�s 0.18 and 0.25 micron manufacturing process for increased processor core frequencies and reduced power consumption. Fully compatible with existing Intel Architecture-based software. A pipelined Floating-Point Unit (FPU) for supporting the 32-bit and 64-bit formats specified in IEEE standard 754, as well as an 80-bit format. Parity-protected address/request and response system bus signals with a retry mechanism for high data integrity and reliability. P6 Dynamic Execution Microarchitecture: Multiple branch prediction: predicts program execution through multiple branches, accelerating the flow of work to the processor. Dataflow analysis: Creates an optimized, reordered schedule of instructions by analyzing data dependencies between instructions. Speculative execution: carries out instruction execution speculatively and based upon this optimized schedule, ensures that the processor�s superscalar execution units remain busy, boosting overall performance. Dual Independent Bus (DIB): The Pentium� III processor supports the high-performance Dual Independent Bus (DIB) architecture. The DIB architecture places the level 2 cache on a dedicated, high speed cache bus allowing for the system bus to be freed up from cache traffic. This provides significantly higher overall system bandwidth and allows for a dramatic improvement in system performance and scaleability. Non-Blocking Level 1 Cache: The Pentium� III processor includes two separate 16 KB level 1 (L1) caches, one for instruction and one for data. The L1 cache provides fast access to the recently used data, increasing the overall performance of the system. Internet Streaming SIMD Extensions: The Internet Streaming SIMD Extensions consist of 70 new instructions and includes single instruction, multiple data for floating-point, additional SIMD-integer and cacheability control instructions. Higher resolution and quality images can be viewed and manipulated better than previously possible High quality audio, MPEG2 video, and simultaneous MPEG2 encoding and decoding Reduced CPU utilization for speech recognition, as well as higher accuracy and faster response times Features Used for Testing and Performance Monitoring: Built-in Self Test (BIST) provides single stuck-at fault coverage of the microcode 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 III processor and system connections through a standard interface. Internal performance counters for performance monitoring and event counting. Incorporates an on-die diode that can be used to monitor the die temperature. A thermal sensor located on the motherboard can monitor the die temperature of the Pentium III processor for thermal management purposes This processor requires a SLOT 1 Type motherboard. ).
