Design Of An IEEE 1394-Compliant Physical Layer IP Core

As a high-speed serial interface, IEEE 1394 was designed with a rich set of features. In addition to providing high-speed access, IEEE 1394 supports peer-to-peer communication, Plug-and-Play connections, hot swapping, and isochronous data transfer, making it ideal for connecting electronics devices and personal computers. IEEE 1394 is currently a composite of three documents: the original IEEE Std 1394-1995, the IEEE Std 1394a-2000 amendment, and the IEEE Std 1394b-2002 amendment. The most widely used version of FireWire is 1394a,This is a supplement to the original 1394-1995 specification.The goal of this project is to design an IEEE 1394a-2000 compliant physical Layer IP core and performance as a 1394a node with the link layer core designed by another team member.The PHY (physical layer) provides the electrical and mechanical interface between the device and the cable and ensures that all devices have fair access to the bus. When you add or disconnect a device, the serial bus will automatically reconfigure itself. This mechanism is managed by the PHY.The paper describes the PHY architecture and the hardware design solutions we used to satisfy the IEEE 1394a specifications. Presently, the RTL coding of the Physical Layer IP core has been finished, and the design has accomplished the original goals of the project.This PHY layer core provides the digital physical layer functions needed to implement a three-ports node in a cable based serial bus, including bus initialization which is composed of three phases: reset, tree identify, and self-identify, normal arbitration, and transmit, receive, or repeat packets.
