IDE/ATA Interface Controller

This reference design implements a generic IDE interface controllercompliant with the ATA/ATAPI-5 Standard. It is also a WISHBONE-compliant host controller that provides a simpleinterface to low-cost, non-volatile memories such as hard disk drives, CD-ROM players/writers and CompactFlashand PC card devices. This document and the design are based on the OpenCores ATA/ATAPI-5 core.

Features

• ATA/ATAPI Revision 5 compliant design
• Common PIO (Programmed Input Output) compatible timing setting for all connected devices
• Fast PIO dataport timing settings for connected devices
• Single-word/multi-word timing settings for connected devices
• PIO mode that supports PINGPONG read and write
• Automatic big endian versus little endian conversion
• DMA read and write buffer
• WISHBONE DMA engine compatible
• WISHBONE Revsion B2 compliant
• 32-bit host interface
• Operation in a wide range of input clock frequencies
