ATA-4 Core for Altera SOPC Builder

Features | Target Device | Block Diagram | Contact |

Description

The ATA-4 / UDMA-33 IDE Avalon Core is a drop-in ATA-Host IP core used for interfacing to an ATA-device. The core has all connections to interface to an Avalon bus and IDE bus. Two Avalon buses are used in the design. One bus controls writing to and reading from the taskfile registers needed for the data transactions. The second Avalon bus reads and writes the data to the ATA hard drive when a transaction is initiated. It handles all transactions on the IDE bus for various commands that are dispatched from the system.

The ATA-4 Avalon core from Nuvation is available either as an encrypted Netlist or as a source code license. This core is also available in Altera SOPC Builder for seamless integration into any design.
