737 views

Published on

OpenVPX combines the power of the latest technology with an open and interoperable standard backed by the VITA Standards Organization.
OpenVPX provides a migration path from VME, VXS, VPX and similar backplane-based standards into cutting-edge technology.

New Trends with VME and OpenVPX - Part 1

  1. 1. New Trends with VME/VPX – Part 1 An historical perspective with a look at the future
  2. 2. Overview Part 1 • VME: how it all started • VME: motivations • VME: electrical features • VME: mechanical features • VME: enhancements (VME64, 2eSST, etc) • VME64: An example - Advme8028 • VME64x + 2eSST: An example - Advme8027 • VME: CPU architectures Part 2 • From VME to VPX • VPX - OpenVPX • OpenVPX: basics • OpenVPX: MultiGig RT2 connector • OpenVPX: planes and profiles • OpenVPX: 2 level maintenance • OpenVPX: an example
  3. 3. VME: how it all started 1980: Motorola + Mostek + Signetics VME begins as the sum of two standards: Eurocard (mechanical) + VERSAbus (electrical) In that moment, many different proprietary solutions existed Lack of standardization was inhibiting cross-compatibility, etc With VME, an open standard was created. Its adoption generated a multibillion market that is still very strong. Being open, VME has been adopted by a significant number of vendors that offer interoperable platforms
  4. 4. VME: motivations VME promised and delivered great value to the customer: • Simple maintenance • Rugged and reliable systems • Lots of flexibility in configurations • Interoperability • Support for real time control These qualities have made VME a choice in many high end and long term applications, including: defense, transportation, medical, aerospace, high end industrial
  5. 5. VME: electrical features Historically, the first concept of VME was very close to an extension of the Motorola 68K CPU It gradually became standardized and incorporated some important features (IEEE-1014-1987): • MASTER/SLAVE architecture. • Asynchronous bus (no clocks are used to coordinate data transfers). • Variable speed handshaking protocol. • Non-multiplexed bus. • Addressing range between 16 and 32-bits. • Data path widths of between 8 and 32-bits. • Bandwidths up to 40 Mbyte/second. • Multiprocessing capability. • Interrupt capability.
  6. 6. VME: mechanical features VME is a backplane pluggable standard that has been designed with the Eurocard form factors (IEEE 1101.1): • 3U, 6U or 9U height – 9U not common today • Single or double width (1 or two slots) • Length: 160mm or 340mm • One backplane can have up to 21 slots (19”) 6U P1 P2 3U P1
  7. 7. VME: mechanical features In VME, two types of connectors to the backplane are defined: 96 pins (VME and VME64) or 160 pins (VME64x) P1 (3U&6U) P2 (6U only) VME, VME64 96 pins (16D+24A) 96 pins (16D+8A ext; 64 user defined) VME64x 160 pins (more user I/O) 160 pins (more user I/O) Note: The 68K CPU had 32/32 internal busses, but 24/16 external busses VME, VME64 VME64x Note: VME64x allows also one 95 pin connector (P0) for high speed signals
  8. 8. VME: mechanical features VME, VME64 VME64x 96 pins 160 pins VME64x VME64
  9. 9. VME: enhancements (VME64, 2eSST, etc) VME has been improved and extended over time; some examples: • VME64 (ANSI/VITA 1-1994) – 64D/64A for 6U boards. – 32D/ 40A for 3U boards. – Twice the bandwidth (up to 80 Mbytes/sec). – Automatic 'plug-and-play' features. • VME64x (1997) – A new 160 pin connector family. – A 95 pin P0/J0 connector. – Higher bandwidth bus cycles (up to 160 Mbytes/sec). – 141 more user-defined I/O pins. – Rear plug-in units (transition modules). – Live insertion / hot-swap capability. • VME320 [2eSST] (1997/98) – 320MB/s and new backplane technology
  10. 10. VME64: An example - Advme8028 6U with Intel® Atom™ CPU Eurotech Advme8028 is a VME64 board VME, VME64 96 pins PMC slots
  11. 11. VME64x + 2eSST: An example - Advme8027 6U with Intel® Core 2 Duo™ Eurotech Advme8027 is a VME64x board with 2eSST support VME64x 160 pins PMC slotsXMC slots
  12. 12. VME: CPU architectures VME was born to support the Motorola 68K, but it is versatile: • PPC – PPC based designs are very popular – E.g. Altivec support (PPC) + VME ruggedness and easy maintenance = great success in Defense applications • X86 – Many designs have incorporated x86 CPUs – Large software base and lots of tools For examples of VME boards, please check: www.eurotech.com
