Memory 65
Memory
Matrox Solios eV-CL has on-board acquisition memory. It has 128, 256, or
512 Mbytes of linearly addressable 32-bit 216 MHz DDR2 SDRAM to store
acquisition data. This memory has a memory bandwidth of 1.73 Gbytes/sec.
PCI-X to PCIe bridge
The PCI-X to PCIe bridge handles the Matrox Solios eV-CL board’s PCIe
connection to the Host. On-board, Matrox Solios eV-CL uses PCI-X technology
to communicate. To communicate with the Host, Matrox Solios eV-CL transfers
data using the Host’s PCIe bus. The PCI-X to PCIe bridge handles the protocol
conversion.
Under optimum conditions, Matrox Solios eV-CL can exchange data with the
Host at a peak transfer rate of up to 1 Gbyte/sec; the maximum achievable
bandwidth depends on the type of camera and digitizer configuration format
(DCF) used. Optimum conditions include using the board in a PCIe slot with 4
active lanes.
Matrox Solios eV-CL can transfer data between its acquisition memory and the
Host’s physically contiguous, non-paged memory without the help of the Host
CPU.
