1.3.2 Intel
•
The Intel
processor architecture. It has been designed to interface with the Intel
processor's system bus at 100 MHz. Along with its Host-to-PCI bridge interface, the 82443GX
host bridge controller has been optimized with a 100 MHz SDRAM memory controller and
data path. The 82443GX also features the Accelerated Graphics Port (AGP) interface. The
82443GX component includes the following functions and capabilities:
•
Support for single and dual Intel
•
64-bit GTL+ based system data bus Interface
•
32-bit system address bus support
•
64/72-bit main memory interface with optimized support for SDRAM
•
32-bit PCI bus interface with integrated PCI arbiter
•
AGP interface with up to 133 MHz data transfer rate
•
Extensive data buffering between all interfaces for high throughput and concurrent operations
