Storage IP Core ATAIF ATA/IDE/ATAPI ATA-8 Interface Core
Implements a host controller for non-volatile memory devices using the parallel interface known as ATA (Advanced Technology Attachment), IDE (Integrated Drive Electronics), and ATAPI (Advanced Technology Attachment Packet Interface). Complies with standard ATA-8.
The core provides a simple interface to memory devices such as hard-disk drives, DVD players, CDROM players/writers, Compact Flash storage, and PC Card devices. It supports PIO modes 0 to 4; Multi-word DMA modes 0, 1 and 2; Ultra ATA -33, -66, -100 and -133; and implements an interface to the IDE bus.
Developed for easy reuse in ASIC and FPGA implementations, the core is strictly synchronous, with positive-edge clocking, no internal tri-states, and a synchronous reset; scan insertion is straightforward.
See representative implementation results (each in a new pop-up window):
Applications
- IDE disk drive, CDROM player/writer & DVD player controllers
- Compact Flash and PC-Card readers
- Systems utilizing IDE/ATA and ATAPI drives for data storage including notebook and desktop computers, servers, set-top boxes and test equipment
