1. Welcome to MEDIATOR PCI 3000D
Thank you for purchasing the MEDIATOR PCI 3000D us oard. Please read the
manual carefully efore the installation.
1.1. Hardware Features
MEDIATOR PCI 3000D is ased on ELBOX high performance core logic
implementation optimised for all Amiga Processor cards in order to deliver high
computation performance:
• 5 PCI slots (PCI 2.1 compati le)
For simultaneous use of up to five PCI cards fully assimilated in the Amiga
environment.
• 33MHz PCI clock (66MHz with SharkPPC G3/G4)
With the PCI clock running at 33MHz, data transfers are executed with the
andwidth of up to 132MB/S and up to 264MB/S for 66MHz clocking.
• 32- it PCI datapatch
Longword transfers are supported in all data transfer types: PCI to Amiga, Amiga
to PCI and PCI to PCI.
• 4GB PCI memory space
Mediator PCI 3000D allows access to the entire 4GB of the PCI memory space.
Access to the entire PCI memory space is executed through the 512MB window
in the Zorro III space. With a hardware-supported paging mechanism, PCI
memory access is executed without any slowdown compared to the linear
memory access.
• Busmastering/DMA in all PCI slots
Mediator PCI supports the usmastering mechanism in all its PCI slots. The PCI
cards in the usmaster mode can offer extremely fast DMA access (up to
132MB/S) without any CPU load. Up to five PCI usmaster cards may e used
simultaneously in Mediator.
• SDRAM/SGRAM of PCI gfx card as system memory
Mediator 3000D can use part of the graphic card memory for Amiga system
needs. Thus, the entire system gains in effectiveness ecause graphic card's
SDRAM/SGRAM memory modules are a out 10x faster than FastRAM memory
in Amiga tur o cards. With very short access time in SDRAM/SGRAM, several
PCI usmaster cards may use this memory simultaneously. The PCI cards may
then rush at the data transfer rate of up to 132MB/S without any CPU load
whatsoever.
