Part Number : EP423
Overview :
The EP423 64-bit PCI-X host bridge core is optimized to operate in both PCI mode and PCI-X mode. The user interface is a highly efficient and flexible user interface which provides for easy integration with other user logic. This PCI-X core automatically switch between PCI and PCI-X protocol based on the system environment. It supports both PCI version 2.3 and PCI-X version 1.0b.
The EP423 64-bit PCI-X host bridge core is designed so that user interface can operate at any clock speed independent of the PCI bus speed. The user interface clock and PCI bus clock can be synchronous our asynchronous to each other.
Features : - Fully supports PCI 2.3 and PCI-X protocol 1.0b.
- Designed for ASIC and PLD implementations.
- Fully static design with edge triggered flip-flops.
- Efficient user interface for different types of user devices.
- User interface and PCI interface runs at different clock speed.
- User interface independent of PCI or PCI-X configuration.
- Include data buffer and synchronization logic to bridge the two clock domains.
- Automatic detection of PCI and PCI-X bus systems.
- Combined bus master and target functions including split completion.
- Host bridge function to initiate configuration access with internal CONFIG_ADDR and CONFIG_DATA registers.
- Supports Zero wait state and user inserted wait state burst data transfer.
- Dual write buffer in each direction to support write data posting.
- Automatic handling of configuration register read/write access.
- Parity generation and parity error detection.
- Includes all PCI and PCI-X specific configuration registers.
- Supports high speed bus request and bus parking.
