Similarities:High speed interfacesCapable of 160 MB/sec data transfersDeliver 32-bit word transfersOperation independent of the VMEbusAdopted as industry standards by VITA
Differences:Everything else!

What is FPDP?What is FPDP?
Front Panel Data Port (FPDP) is a high speed synchronous bus
Adopted as an industry standard - ANSI/VITA 17-1998 (www.vita.com)
Delivers 32-bit word transfers between VME boards at up to 160MB/sec
Operation is completely independent of the VMEbus
Communication is through front panel 80-pin connectors via ribbon cable

FPDP FeaturesFPDP Features
High Speed Data Transfer - up to 160 MB/sec Depending on Clock Signal Used
Ports can be Configured to Transmit or Receive Data under Software Control
No Address or Arbitration Cycles; Data Rates Fully Defined by Clock Frequency
Connects Multiple Boards in the Same VMEbus Chassis, or Between Multiple Chassis
Allows Integration w/ Other Vendors Boards

FPDP Data TransfersFPDP Data Transfers Master device generates a free-running
clock (TTL or PECL). Pentek products support both, default to PECL.
Clock frequency defines the maximum transfer rate - 80 MB/sec for TTL or 160 MB/sec for PECL
Interface is configured as transmitter or receiver using software control
Data can be sent in either framed or unframed form. Pentek products support transfer of unframed data

New FPDP Technology: FPDP IINew FPDP Technology: FPDP II
Increased Bandwidth using Double-Edged Clocking
Data Transfer Rates more than Doubled: 400 MB/sec using 50 MHz Clock
Backwards CompatibleCan use TTL Clock up to 20 MHz, or PECL
Clock up to 50 MHzCan Switch between Double and Single-Edged
Clock SettingsUses same 80-Pin Ribbon Cable and
Connector as Current FPDP

What is RACEway?What is RACEway?
High speed synchronous backplane fabric
Adopted as an industry standard - ANSI/VITA 5.1-1999 (www.vita.com)
Delivers 32-bit word transfers between VME boards at up to 160MB/sec
Operation is completely independent of the VMEbus
RACEway Interlink Modules (ILKs) connect VME boards to the RACEway backplane fabric - bridge up to 16 slots

High Speed Data Transfer -160MB/sec, 1280 MB/sec aggregate (ILK16)
Simultaneous Data Transfers
Unique Crossbar Switch Technology User Selectable Priority Control
Adaptive Routing: Automatic Selection of Alternate Path when First Not Available
Broadcast to Multiple Slaves with a Single Data Transfer

RACEway Crossbar Switch Uses six independent 32-bit bi-directional ports for data routing
Can perform up to three simultaneous transfers of 160 MB/sec each
Each port controls arbitration, direction, priority, & handshaking
Each port can transmit data to any other port on the switch, or can broadcast to all five at aggregate rate of 800 MB/sec
