ATAIF - parallel ATA Disk Host Controller

alt

The ATAIF 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). The IP provides a simple interface to memory devices such as  hard-disk drives, CDROM/DVD 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.

Highlights

  • Supports one or two IDE devices
  • Supports synchronous Ultra ATA-33, -66, -100 and -133
  • Programmable I/O modes: 0, 1, 2 and 4
  • Multi-word DMA modes: 0, 1 and 2
  • Generic SFR interface with a configurable 8/16/32-bit data bus
  • Configurable internal FIFO address bus width - min. 4-bit, no upper limit
  • Uses either the DMA Controller or the Master FIFO controller for the data transmission interface

Benefits

Complies with ATA-8 Standard

Flexible, can be configured for connectivity and control of various mobile, peripheral and memory technologies

The optional ATAIF Software Driver provides the user with a full access to the functionality provided by the ATAIF host controller core

The following parameters allow adjusting the ATAIF core to requirements of target application or technology:

  • SFR data bus width
  • DMA address/data bus width
  • Master FIFO data bus width
  • Configurable Internal FIFO address bus width
  • Size of the counter for transmission size

The DMA controller block can be implemented alternatively instead of Master FIFO controller.

  • IDE disk drive, CDROM player/writer & DVD player controllers
  • Compact Flash and PC-Card readers
  • Data acquisition systems
  • Systems utilizing IDE/ATA and ATAPI drives for data storage including notebook and desktop computers, servers, set-top boxes and test equipment

Deliverables

  • VHDL/Verilog source code
  • Synthesis support for Synopsys® and Cadence tools with a set of synthesis scripts 
  • Simulation support for Mentor Graphics® and Cadence® tools with a set of scripts and macros 
  • Extensive VHDL/Verilog 2001 test bench
  • Documentation
  • 30 days of technical support 
  • 90 days of warranty against defects

Delivery Options

  • EDIF netlist for FPGA and low volume production
  • Reference design for proprietary evaluation board
  • AMBA® AHB, OPB or Avalon system bus interface
