Intel® 945G Express Chipset Development Kit User's Manual Development Kit Features 2.4.2 Note: 2.5 ⎯ System Management mode ⎯ Multiple low-power states • Optimized for 32-bit applications running on advanced 32-bit operating systems Intel® Celeron® D Processor 341 This processor is not available in this development kits The Intel® Celeron® D Processor provides exceptional value and balanced performance with efficient power usage. It is binary compatible with previous Intel Architecture processors. Features of the processor include: • Binary compatible with applications running on previous members of the Intel microprocessor line • NetBurst microarchitecture • Support EM64T Technology • System bus frequency at 533 MHz • Rapid Execution Engine: Arithmetic Logic Units (ALUs) run at twice the processor core frequency. • Hyper Pipelined Technology ⎯ Advance Dynamic Execution ⎯ Very deep out-of-order execution • Enhanced branch prediction • 16 KByte Level 1 data cache • 256 KByte Advanced Transfer Cache (on-die, full-speed Level 2 (L2) cache) with 8way associatively and Error Correcting Code (ECC) • 144 Streaming SIMD Extensions 2 (SSE2) and 13 Streaming SIMD Extensions 3 (SSE3) instructions. • Power Management capabilities ⎯ System Management mode ⎯ Multiple low-power states • Optimized for 32-bit applications running on advanced 32-bit operating systems Intel® 945G Express Chipset Features and Operation The Intel 945G Express Chipset platform is designed based on the 32-bit IA-32 Intel® Architecture. The MCH connects to the processor as shown in Figure 1. The primary role of an MCH in a system is to manage the flow of information between its interfaces: the processor interface (FSB), the system memory interface (DRAM controller), the integrated graphics interface, the external graphics interface (PCI Express), and the I/O controller through the DMI interface. This includes arbitrating between the four interfaces when each initiates transactions. The ICH7 will provide extensive I/O support. The functions and capabilities include PCI Express, PCI, Serial ATA, USB, IDE, and much more. 16 Reference #308823
