The GL9701 is composed of the following major functional blocks as shown in Figure 3-1:
PCI interface macro
The macro acts as either a bus master or a bus slave and handles the PCI protocol depending on the
transaction types. GL9701 supports 32-bit PCI addressing with 0MHz~33MHz and 66MHz operation
frequency.

Supported PCI Command
Bus Arbiter
This block supports PCI bus arbiter for secondary PCI bus. The bus arbitration is provided by GL9701
and supports up to five external masters. The arbiter can be disabled by external EEPROM.
Configuration Registers
This module supports two mechanisms for configuration space access: PCI compatible and PCI Express
enhanced configuration mechanism.
Power Management
The moudle is in charge of power management event signaling. This module enables GL9701 to enter
software driven D-state transitions.
Transaction Translator
The Transaction Translator manages all the bridge operation between PCI Express and PCI interface. It
is responsible for PCI Express to PCI command translation, message translation and managing
transaction ordering.
