GE VMIPCI-5565 Ultrahigh Speed Fiber-Optic Reflective Memory with Interrupts

GE VMIPCI-5565 Ultrahigh Speed Fiber-Optic  Reflective Memory with Interrupts

INTRODUCTION

VMIPCI-5565 is the PCI member of the GE Fanuc Embedded Systems’ VMIxxx-5565 family of Reflective Memory (RFM) real time network products. The other members of the family are VMIVME-5565, VME-compatible board, and VMIPMC-5565, the PCI mezzanine card (PMC). All three of these products are network compatible, and may be integrated into a network in any combination.

Features:

 • High speed, easy to use fiber-optic network (2.12 Gbaud serially) 

 • Data written to memory in one node is also written to memory in all nodes on the network 

 • Up to 256 nodes 

 • Connection with multimode fiber up to 300m, single mode fiber up to 10km 

 • Dynamic packet size, 4 to 64 bytes of data 

 • Transfer rate 47.1MB/s (4 byte packets) to 174MB/s (64 byte packets)

 • Two independent DMA channels

 • Any node on the network can generate an interrupt in any other node on the network or in all network nodes with a single command • Error detection   • Redundant transfer mode for extra error suppression 

 • No processor overhead 

 • No processor involvement in the operation of the network 

 • PCI 64-bit 66MHz transfers 

 • PCI revision 2.2 compliant

Functional Characteristics

PCI Initiator/Direct Memory Access (DMA) Capabilities: 

The VMIPCI-5565 supports DMA operations. The DMA sequence is initialized by a few control register writes to the VMIPCI-5565 by the host. Therefore, the VMIPCI-5565 becomes a PCI initiator and moves the specified block of data up to 64MB without further host attention. The PCI architecture ensures that the VMIPCI-5565 does not monopolize the PCI bus and causes the VMIPCI-5565’s DMA engine to automatically split large blocks in small bursts. The VMIPCI-5565 can be programmed to issue a PCI interrupt upon completion of DMA process. There are two independent DMA engines, each capable of reading or writing. It is possible for a Read DMA and a Write DMA to occur simultaneously.

Error Management:

 Errors are detected by the VMIPCI-5565 with the use of the error detection facilities of the Fibre Channel encoder/decoder and additional cyclic redundant encoding and checking. When a node detects an error, the erroneous transfer is removed from the system and an interrupt is generated, if enabled.
