3 row P1/P2, 32 bit Xfers, 64 w/ the address bus MUXed @ 40MBytes/second Replaced by ansi/vita 1-1994; VME64 ansi/vita 1-1994 VME64 added 5 Row P1/ny other features vita.1-1997 VME64x; VME64 Extensions which defined the 'z' and 'd' row of P1, added P0 @.
VME64 added a 64bit Multiplexed BLock Transfer mblt which uses the 32 bit data bus and the 32 bit address bus to transfer data.The chassis only need provide the P1 side of the back plane when only 3U cards are used.Patented by Arizona Digital, increased the bus speed to 320 MBps ISO/IEC 60821 or ISO/IEC 821 the old number is the same as ieee ISO/IEC 15776 is the same as ansi/vita 1 1994 Speed Increases with Standard updates; VME32: 40MB/s VME64: 80MB/s same speed for.VME Bus Access estrazione del lotto del 16 08 Timing Diagram The (up-coming) Master makes a Bus Request, the Controller gives a Bus Grant, then asserts Bus Busy.Care should be taken producing a 21 slot chassis, with the addition of slide rails the width may exceed a standard 19" EIA-310 rack.Cypress *These devices are Obsolete and not recommended for new designs* VME Controllers(Master: 32-bit VIC068A / 64-bit VIC64 (Slave: CY7C960 / CY7C961) VME I/O CY7C964 bus interface - used with either the VIC chips or the 9-92010: cmos vmebus Interface Controller; VIC068A; Pin grid array.Once the Controller "Bus Grants" the Master access, the Master drives the Address and Data bus to perform a data transfer to a Slave board.There are a number of other specifications which increase the data through-put even higher by using the "user defined" P2 pins, the P0 connector or by bringing the data out the front panel.
The J2 connector may be either a 3-row (x32) 96-pin or a 5-row (x32) 160-pin connector.
The term Crate may also be used to indicate a VME chassis.Three main types of cards reside on the VME bus.Both tables; Extracted from - VME Interface Board Design Document 1/03/93, Larry Davis The VME Address bus width used by the Master is determined by the setting of the Address Modifier AM codes.LS-573TX, intel Core 2 Duo.25" Miniboard with onboard 6 x LAN, sata, USB.0 port, Audio, RS232/422/485, PCI, Min-PCI, PCI Express Mini card slots interface, CRT and lvds, lV-67E.Based on new SiRF StarIII technology it supports 20-Channel GPS and integrated ultra-high performance two uart ports with up to 15Mbps data rates.VME Bus Description, vMEbus System poker wahrscheinlichkeiten calculator configuration, vME Bus Description.Versa Module Europa, iEEE, vME Description, vME Standards.Under the latest bus specification (which added the 160 pin connector) either connector may be used (but I believe both have to be the same type).'C' and 'D' of the VME spec which was replaced by VME64.The newer versions of the spec added two new enhancements, termed 2eVME and 2eSST.Pixus also provides conduction-cooled and customized OpenVPX enclosure solutions.
