Functional Description

MVME6100 Single Board Computer Installation and Use (6806800D58H)

The SDRAM controller supports a wide range of SDRAM timing parameters. These parameters

can be configured through the SDRAM Mode register and the SDRAM Timing Parameters

additional information and programming details.

The DRAM controller contains four transaction queues—two write buffers and two read

buffers. The DRAM controller does not necessarily issue DRAM transactions in the same order

that it receives the transactions. The MV64360 is targeted to support full PowerPC cache

coherency between CPU L1/L2 caches and DRAM.

4.6.3 Device Controller Interface

The device controller supports up to five banks of devices, three of which are used for Flash

Banks A and B, NVRAM/RTC. Each bank supports up to 512MB of address space, resulting in

total device space of 1.5GB. Serial ports are the fourth and fifth devices on the MVME6100.

Each bank has its own parameters register as shown in the following table.

4.6.4 PCI/PCI-X Interfaces

The MVME6100 provides two 32/64-bit PCI/PCI-X buses, operating at a maximum frequency

of 100 MHz when configured to PCI-X mode, and run at 33 or 66 MHz when running

conventional PCI mode. PCI bus 1 is connected to the PMC slots 1 and 2.

The maximum PCI-X frequency of 100 MHz supported by PCI bus 1 may be reduced depending

on the number and/or type of PMC/PrPMC installed. If PCI bus 1 is set to +5V VIO, it runs at 33

MHz. VIO is set by the keying pins (they are both a keying pin and jumper). Both pins must be

set for the same VIO on the PCI-X bus.
