Overview

The GL711FW is a high-performance 1394 to ATA/ATAPI native bridge with an embedded SBP-2 target solution. It supports a solution for link/transaction layer controller conforming to the IEEE Std 1394 (IEEE 1394-1995 and IEEE 1394.a) up to 400Mbps transfer rate. Through the SBP-2 port driver, supported by Microsoft Windows 2000 and Windows 98 SE, Windows ME, SCSI class drivers can use SBP-2 to communicate with IEEE 1394 device using the SCSI command set.

Features

● Data transfer rates of S100, S200 and S400

● Fully interoperable with implementation of IEEE-1394(1995) and IEEE 1394.a-2000 compliant

● Standard PHY/link Interface

● Firmware support for SBP-2 target agent

● Fully ATA/ATAPI-6 compliant.

● Supports IDE PIO modes and DMA modes and Ultra DMA modes up to UDMA100.

● Embedded RAM, ROM and micro-processor.

● External Flash ROM interface for easy updating firmware code.

● Automatic SBP-2 protocol management by an internal hardware engine to improve performance and firmware efficiency

● Auto acknowledge-code response for all packets that targeted to Management/Command ORB agent SBP-2 protocol engine:

- Automatic Management ORB fetch

- Linked Command ORB fetch

- Auto address increment DMA for both direct and indirect addressing

● Automatic Page Table fetching

● Dedicated asynchronous data transfer

● Automatic packing/de-packing for asynchronous transmit/receive data of DMA
