The Common MR Communications Link is first used in the DVMR product development. In SV,
we use the same communication link.
SerialLite is a serial protocol developed by Altera Corp. and Innocor Ltd. Altera provides an IP
core implementation of SerialLite that utilizes the high-speed serial transceivers in their
Stratix GX FPGAs. This communications link assumes implementation in a Stratix GX FPGA
using the Altera IP core.
The DVMR Common Communications Link, or dvmrlink, defines bidirectional data transfer
within the DVMR system. This includes data transfer between the CAM chassis and remote
devices, including RF Exciters, RF Receivers, and data transfer between an RF Receiver and a
VRF installed a VRE. IRF3 board is the interface of DVMR link.
1. DATA TRANSFER FROM CAM TO REMOTE DEVICES
Data transfer from CAM to the remote devices includes both synchronous and
asynchronous data. The Sequence Bus, which contains SSP (Sequence Scan Protocol)
Commands, RF data, and gradient data, is the source of synchronous data. The CAM CPUs,
via the PCI bus, are the sources of asynchronous data. Asynchronous data transfer
effectively provides PCI write access to the remote devices. Synchronous and asynchronous
data is merged into an CAM data packet.
2. DATA TRANSFER FROM REMOTE DEVICES
Data transfer from the remote devices include status information, sample data, echoed SSP
commands, and echoed PCI commands.
3. Data Transfer from VRF to Remote Receivers
In SV system, the 8 channel RF signals are digitized by ADC in RRX and converted into optical
signal, send to VRF in VRE via VRF Data Link.
