The new Intel® Celeron™ processor, at 266MHz, is Intel’s first entry into the Basic PC (sub-$1200) market segment. The Intel Celeron processor meets the core needs and affordability requirements common to many new users. The Intel Celeron processor provides the performance for applications running on operating systems such as Windows* 95. The processor core has 7.5M transistors and is based on Intel’s advanced 0.25 micron CMOS process technology. In addition, the Intel Celeron processor benefits from the same P6 microarchitecture core as the Pentium® II processor. The Intel Celeron processor is provided in the Single Edge Processor Package (SEPP) enabling ease of design, as well as cost efficiency. This new processor is backed by Intel’s more than 25 years of experience engineering and manufacturing high quality, reliable microprocessors. Discover how Intel Celeron processor features and benefits can enhance your basic computing experience: Product Highlights Dynamic Execution Techology Intel® MMX™ Technology Other Significant Features Testing and Performance Monitoring Features Performance Specifications Product Highlights Provides a base level of functionality to meet the core needs and affordability requirements common to new home and business PC users. Available at 266MHz. Based on the Intel P6 microarchitecture, the same microarchitecture the Pentium II processor is based on. Includes Intel’s media-enhancing MMX™ technology. Offers Dynamic Execution technology. Utilizes Intel’s 0.25 micron manufacturing process for increased processor core frequencies and reduced power consumption. Provides competitive functionality on all three vectors of performance—floating point, integer and multimedia. Utilizes the Intel P6 microarchitecture’s multi-transaction system bus at 66MHz. Includes a 32K (16K/16K) non-blocking, level-one cache that provides fast access to heavily used data. Available in the Single Edge Processor Package (SEPP) form factor, which maintains compatibility with Slot 1. P6 Microarchitecture Dynamic Execution Technology Multiple Branch Prediction: Predicts program execution through several 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 instructions speculatively and based on this optimized schedule, ensures that the processor’s superscalar execution units remain busy, boosting overall performance. Intel® MMX™ Media Enhancement Technology Intel’s MMX technology includes new instructions and data types that allow applications to achieve a new level of performance. Intel’s MMX technology is designed as a set of basic, general-purpose integer instructions that are easily applied to the needs of a wide diversity of multimedia and communications applications. The highlights of the technology are: Single Instruction, Multiple Data (SIMD) technique 57 new instructions Eight 64-bit wide MMX technology registers Four new data types Other Significant Features Single Edge Processor Package (SEPP), which is similar to the Single Edge Contact (SEC) cartridge form factor that the Pentium II processor uses, and maintains compatibility with Slot 1. This packaging technology features a P6-microarchitecture-based core processor on a single-sided substrate without BSRAM componentry. It does not have a thermal plate or cover. The 0.25 micron manufacturing process, which reduces processor heat, enables the Intel Celeron processor to use a smaller heat sink. Also, the Intel Celeron processor uses newer Retention Mechanisms that are designed to fit the SEPP form factor. The system bus supports multiple outstanding transactions to increase bandwidth availability. Incorporates separate 16K level-one caches, one for instructions and one for data. 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. Testing and Performance Monitoring Features Built-in Self Test (BIST), providing 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 Intel Celeron processor and system connections through a standard interface. Internal performance counters for performance monitoring and event counting. Performance Specifications
